Constant-Time Encoding
[](https://github.com/paragonie/constant_time_encoding/actions)
[](https://packagist.org/packages/paragonie/constant_time_encoding)
[](https://packagist.org/packages/paragonie/constant_time_encoding)
[](https://packagist.org/packages/paragonie/constant_time_encoding)
[](https://packagist.org/packages/paragonie/constant_time_encoding)
Based on the [constant-time base64 implementation made by Steve
"Sc00bz" Thomas](https://github.com/Sc00bz/ConstTimeEncoding),
this library aims to offer character encoding functions that do not leak
information about what you are encoding/decoding via processor cache
misses. Further reading on [cache-timing
attacks](http://blog.ircmaxell.com/2014/11/its-all-about-time.html).
Our fork offers the following enchancements:
* `mbstring.func_overload` resistance
* Unit tests
* Composer- and Packagist-ready
* Base16 encoding
* Base32 encoding
* Uses `pack()` and `unpack()` instead of `chr()` and `ord()`
## PHP Version Requirements
Version 2 of this library should work on **PHP 7** or newer. For PHP 5
support, see [the v1.x
branch](https://github.com/paragonie/constant_time_encoding/tree/v1.x).
If you are adding this as a dependency to a project intended to work on
both PHP 5 and PHP 7, please set the required version to `^1|^2` instead of
just `^1` or `^2`.
## How to Install
```sh
composer require paragonie/constant_time_encoding
```
## How to Use
```php
use ParagonIE\ConstantTime\Encoding;
// possibly (if applicable):
// require 'vendor/autoload.php';
$data = random_bytes(32);
echo Encoding::base64Encode($data), "\n";
echo Encoding::base32EncodeUpper($data), "\n";
echo Encoding::base32Encode($data), "\n";
echo Encoding::hexEncode($data), "\n";
echo Encoding::hexEncodeUpper($data), "\n";
```
Example output:
```
1VilPkeVqirlPifk5scbzcTTbMT2clp+Zkyv9VFFasE=
2VMKKPSHSWVCVZJ6E7SONRY3ZXCNG3GE6ZZFU7TGJSX7KUKFNLAQ====

d558a53e4795aa2ae53e27e4e6c71bcdc4d36cc4f6725a7e664caff551456ac1
D558A53E4795AA2AE53E27E4E6C71BDCC4D36CC4F6725A7E664CAFF551456AC1
```
If you only need a particular variant, you can just reference the
required class like so:
```php
use ParagonIE\ConstantTime\Base64;
use ParagonIE\ConstantTime\Base32;
$data = random_bytes(32);
echo Base64::encode($data), "\n";
echo Base32::encode($data), "\n";
```
Example output:
```
1VilPkeVqirlPifk5scbzcTTbMT2clp+Zkyv9VFFasE=
2vmkkpshswvcvzj6e7sonry3zxcng3ge6zzfu7tgjsx7kukfnlaq====
```
## Support Contracts
If your company uses this library in their products or services, you may be
interested in [purchasing a support contract from Paragon Initiative
Enterprises](https://paragonie.com/enterprise).

DES-EDE3-CBC isn't, nor is its key derivation
function. As is, the definitive authority on this encoding
scheme isn't the IETF but rather OpenSSL's
own implementation. ie. the implementation *is* the standard
and any bugs that may exist in that

* PHP version 5
*
* Used by PHP's openssl_public_encrypt() and openssl's rsautl
(when -pubin is set)
*
* Processes keys with the following headers:
*
* -----BEGIN ENCRYPTED PRIVATE KEY-----
* -----BEGIN PRIVATE KEY-----
* -----BEGIN PUBLIC KEY-----
*
* Analogous to ssh-keygen's pkcs8 format (as specified by -m).
Although PKCS8
* is specific to private keys it's basically creating a DER-encoded
wrapper
* for keys. This just extends that same concept to public keys (much like
ssh-keygen)

* echo $rijndael->encrypt(substr($plaintext, 16, 16));
* </code>
* <code>
* echo $rijndael->encrypt($plaintext);

*
* The solution is to enable the continuous buffer. Although this will
resolve the above discrepancy, it creates

*
* <code>
* $rijndael->encrypt(substr($plaintext, 0, 16));

output. With it enabled, they yield different

it's disabled, they remain constant.
*
* Put another way, when the continuous buffer is enabled, the state of
the \phpseclib3\Crypt\*() object changes after each

constant. For this reason, it's recommended that

are, in fact, sometimes required (SSH uses them),

* - $self (object reference to it self. Do not use $this, but
$self instead)
* - $in (the content of $in has to en/decrypt by the generated

* Generalized Koblitz Curves over y^2 = x^3 + b.
*
* According to http://www.secg.org/SEC2-Ver-1.0.pdf Koblitz curves are
over the GF(2**m)
* finite field. Both the $a$ and $b$ coefficients are either 0 or 1.
However, SEC2
* generalizes the definition to include curves over GF(P) "which
possess an efficiently
* computable endomorphism".
*
* For these generalized Koblitz curves $b$ doesn't have to be 0 or 1.
Whether or not $a$
* has any restrictions on it is unclear, however, for all the GF(P)
Koblitz curves defined
* in SEC2 v1.0 $a$ is $0$ so all of the methods defined herein will assume
that it is.
*
* I suppose we could rename the $b$ coefficient to $a$, however, the
documentation refers
* to $b$ so we'll just keep it.
*
* If a later version of SEC2 comes out wherein some $a$ values are
non-zero we can create a

/* in theory this should be faster than regular modular reductions
save for one small issue.
to convert to / from base-2**8 with BCMath you have to call
bcmul() and bcdiv() a lot.
to convert to / from base-2**8 with PHP64 you have to call
base256_rshift() a lot.
in short, converting to / from base-2**8 is pretty expensive and
that expense is
enough to offset whatever else might be gained by a simplified
reduction algorithm.
now, if PHP supported unsigned integers things might be
different. no bit-shifting
would be required for the PHP engine and it'd be a lot
faster. but as is, BigInteger
uses base-2**31 or base-2**26 depending on whether or not the

/**
* brainpoolP160t1
*
* This curve is a twisted version of brainpoolP160r1 with A = -3. With
brainpool,
* the curves ending in r1 are the "regular" curves and the
curves ending in "t1"
* are the twisted version of the r1 curves. Per
https://tools.ietf.org/html/rfc5639#page-7
* you can convert a point on an r1 curve to a point on a t1 curve thusly:
*
* F(x,y) := (x*Z^2, y*Z^3)
*
* The advantage of A = -3 is that some of the point doubling and point
addition can be

/**
* Pure-PHP implementation of Blowfish.
*
* Uses mcrypt, if available, and an internal implementation, otherwise.
*
* PHP version 5
*
* Useful resources are as follows:
*
* - {@link http://en.wikipedia.org/wiki/Blowfish_(cipher) Wikipedia
description of Blowfish}
*
* # An overview of bcrypt vs Blowfish
*
* OpenSSH private keys use a customized version of bcrypt. Specifically,
instead of
* encrypting OrpheanBeholderScryDoubt 64 times OpenSSH's bcrypt
variant encrypts
* OxychromaticBlowfishSwatDynamite 64 times. so we can't use crypt().
*
* bcrypt is basically Blowfish but instead of performing the key expansion
once it performs
* the expansion 129 times for each round, with the first key expansion
interleaving the salt
* and password. This renders OpenSSL unusable and forces us to use a
pure-PHP implementation
* of blowfish.
*
* # phpseclib's four different _encryptBlock() implementations
*
* When using Blowfish as an encryption algorithm, _encryptBlock() is
called 9 + 512 +
* (the number of blocks in the plaintext) times.
*
* Each of the first 9 calls to _encryptBlock() modify the P-array. Each of
the next 512
* calls modify the S-boxes. The remaining _encryptBlock() calls operate on
the plaintext to
* produce the ciphertext. In the pure-PHP implementation of Blowfish these
remaining
* _encryptBlock() calls are highly optimized through the use of eval().
Among other things,
* P-array lookups are eliminated by hard-coding the key-dependent P-array
values, and thus we
* have explained 2 of the 4 different _encryptBlock() implementations.
*
* With bcrypt things are a bit different. _encryptBlock() is called
1,079,296 times,
* assuming 16 rounds (which is what OpenSSH's bcrypt defaults to).
The eval()-optimized
* _encryptBlock() isn't as beneficial because the P-array values are
not constant. Well, they
* are constant, but only for, at most, 777 _encryptBlock() calls, which is
equivalent to ~6KB
* of data. The average length of back to back _encryptBlock() calls with a
fixed P-array is
* 514.12, which is ~4KB of data. Creating an eval()-optimized
_encryptBlock() has an upfront
* cost, which is CPU dependent and is probably not going to be worth it
for just ~4KB of
* data. Conseqeuently, bcrypt does not benefit from the eval()-optimized
_encryptBlock().
*
* The regular _encryptBlock() does unpack() and pack() on every call, as
well, and that can
* begin to add up after one million function calls.
*
* In theory, one might think that it might be beneficial to rewrite all
block ciphers so
* that, instead of passing strings to _encryptBlock(), you convert the
string to an array of
* integers and then pass successive subarrays of that array to
_encryptBlock. This, however,
* kills PHP's memory use. Like let's say you have a 1MB long
string. After doing
* $in = str_repeat('a', 1024 * 1024); PHP's memory
utilization jumps up by ~1MB. After doing
* $blocks = str_split($in, 4); it jumps up by an additional ~16MB. After
* $blocks = array_map(fn($x) => unpack('N*', $x), $blocks);
it jumps up by an additional
* ~90MB, yielding a 106x increase in memory usage. Consequently, it bcrypt
calls a different
* _encryptBlock() then the regular Blowfish does. That said, the Blowfish
_encryptBlock() is
* basically just a thin wrapper around the bcrypt _encryptBlock(), so
there's that.
*
* This explains 3 of the 4 _encryptBlock() implementations. the last
_encryptBlock()
* implementation can best be understood by doing Ctrl + F and searching
for where
* self::$use_reg_intval is defined.
*
* # phpseclib's three different _setupKey() implementations
*
* Every bcrypt round is the equivalent of encrypting 512KB of data. Since
OpenSSH uses 16
* rounds by default that's ~8MB of data that's essentially being
encrypted whenever
* you use bcrypt. That's a lot of data, however, bcrypt operates
within tighter constraints
* than regular Blowfish, so we can use that to our advantage. In
particular, whereas Blowfish
* supports variable length keys, in bcrypt, the initial "key" is
the sha512 hash of the
* password. sha512 hashes are 512 bits or 64 bytes long and thus the
bcrypt keys are of a
* fixed length whereas Blowfish keys are not of a fixed length.
*
* bcrypt actually has two different key expansion steps. The first one
(expandstate) is
* constantly XOR'ing every _encryptBlock() parameter against the salt
prior _encryptBlock()'s
* being called. The second one (expand0state) is more similar to
Blowfish's _setupKey()
* but it can still use the fixed length key optimization discussed above
and can do away with
* the pack() / unpack() calls.
*
* I suppose _setupKey() could be made to be a thin wrapper around
expandstate() but idk it's
* just a lot of work for very marginal benefits as _setupKey() is only
called once for
* regular Blowfish vs the 128 times it's called --per round-- with
bcrypt.
*
* # blowfish + bcrypt in the same class
*
* Altho there's a lot of Blowfish code that bcrypt doesn't
re-use, bcrypt does re-use the
* initial S-boxes, the initial P-array and the int-only _encryptBlock()
implementation.
*
* # Credit
*
* phpseclib's bcrypt implementation is based losely off of
OpenSSH's implementation:

*
* $plaintext = str_repeat('a', 1024);
*
* echo $blowfish->decrypt($blowfish->encrypt($plaintext));

/**
* The Salsa20 hash function function
*
* On my laptop this loop unrolled / function dereferenced version of
parent::salsa20 encrypts 1mb of text in
* 0.65s vs the 0.85s that it takes with the parent method.
*
* If we were free to assume that the host OS would always be 64-bits
then the if condition in leftRotate could
* be eliminated and we could knock this done to 0.60s.
*
* For comparison purposes, RC4 takes 0.16s and AES in CTR mode with
the Eval engine takes 0.48s.
* AES in CTR mode with the PHP engine takes 1.19s. Salsa20 / ChaCha20
do not benefit as much from the Eval
* approach due to the fact that there are a lot less variables to
de-reference, fewer loops to unroll, etc

* Pure-PHP 32-bit implementation of SHA3
*
* Whereas BigInteger.php's 32-bit engine works on PHP 64-bit this
32-bit implementation
* of SHA3 will *not* work on PHP 64-bit. This is because this
implementation
* employees bitwise NOTs and bitwise left shifts. And the round
constants only work
* on 32-bit PHP. eg. dechex(-2147483648) returns 80000000 on 32-bit
PHP and
* FFFFFFFF80000000 on 64-bit PHP. Sure, we could do bitwise ANDs but
that would slow
* things down.
*
* SHA512 requires BigInteger to simulate 64-bit unsigned integers
because SHA2 employees
* addition whereas SHA3 just employees bitwise operators. PHP64 only
supports signed
* 64-bit integers, which complicates addition, whereas that limitation
isn't an issue
* for SHA3.

* RC4 is also known as ARCFOUR or ARC4. The reason is elaborated upon at
Wikipedia. This class is named RC4 and not
* ARCFOUR or ARC4 because RC4 is how it is referred to in the SSH1
specification.
*
* Here's a short example of how to use this library:
* <code>
* <?php
* include 'vendor/autoload.php';
*
* $rc4 = new \phpseclib3\Crypt\RC4();
*
* $rc4->setKey('abcdefgh');
*
* $size = 10 * 1024;
* $plaintext = '';
* for ($i = 0; $i < $size; $i++) {
* $plaintext.= 'a';
* }
*
* echo $rc4->decrypt($rc4->encrypt($plaintext));
* ?>
* </code>

/**
* Pure-PHP implementation of Rijndael.
*
* Uses mcrypt, if available/possible, and an internal implementation,
otherwise.
*
* PHP version 5
*
* If {@link self::setBlockLength() setBlockLength()} isn't called,
it'll be assumed to be 128 bits. If
* {@link self::setKeyLength() setKeyLength()} isn't called,
it'll be calculated from
* {@link self::setKey() setKey()}. ie. if the key is 128-bits, the key
length will be 128-bits. If it's
* 136-bits it'll be null-padded to 192-bits and 192 bits will be the
key length until
* {@link self::setKey() setKey()} is called, again, at which point,
it'll be recalculated.
*
* Not all Rijndael implementations may support 160-bits or 224-bits as the
block length / key length. mcrypt, for example,
* does not. AES, itself, only supports block lengths of 128 and key
lengths of 128, 192, and 256.
* {@link
http://csrc.nist.gov/archive/aes/rijndael/Rijndael-ammended.pdf#page=10
Rijndael-ammended.pdf#page=10} defines the
* algorithm for block lengths of 192 and 256 but not for block lengths /
key lengths of 160 and 224. Indeed, 160 and 224
* are first defined as valid key / block lengths in
* {@link
http://csrc.nist.gov/archive/aes/rijndael/Rijndael-ammended.pdf#page=44
Rijndael-ammended.pdf#page=44}:
* Extensions: Other block and Cipher Key lengths.
* Note: Use of 160/224-bit Keys must be explicitly set by
setKeyLength(160) respectively setKeyLength(224).
*
* {@internal The variable names are the same as those in
* {@link
http://www.csrc.nist.gov/publications/fips/fips197/fips-197.pdf#page=10

with this library:
* <code>
* <?php
* include 'vendor/autoload.php';

* $private = \phpseclib3\Crypt\RSA::createKey();
* $public = $private->getPublicKey();

* </code>
*
* One thing to consider when using this: so phpseclib uses PSS mode by
default.
* Technically, id-RSASSA-PSS has a different key format than
rsaEncryption. So
* should phpseclib save to the id-RSASSA-PSS format by default or the
* rsaEncryption format? For stand-alone keys I figure rsaEncryption is
better
* because SSH doesn't use PSS and idk how many SSH servers would be
able to
* decode an id-RSASSA-PSS key. For X.509 certificates the id-RSASSA-PSS
* format is used by default (unless you change it up to use PKCS1 instead)

*
* Put another way, when the continuous buffer is enabled, the state of

constant. For this reason, it's recommended that

that x (mod m) = x' (mod m), with x' being smaller than x."
*
* Unfortunately, the "Barrett Reduction with Folding"
algorithm described in thesis-149.pdf is not, as written, all that
* usable on account of (1) its not using reasonable radix points as
discussed in
* {@link http://math.libtomcrypt.com/files/tommath.pdf#page=162 MPM
6.2.2} and (2) the fact that, even with reasonable
* radix points, it only works when there are an even number of digits
in the denominator. The reason for (2) is that
* (x >> 1) + (x >> 1) != x / 2 + x / 2. If x is even,
they're the same, but if x is odd, they're not. See the in-line

/**
* Performs modular exponentiation.
*
* The most naive approach to modular exponentiation has very
unreasonable requirements, and
* and although the approach involving repeated squaring does vastly
better, it, too, is impractical
* for our purposes. The reason being that division - by far the most
complicated and time-consuming
* of the basic operations (eg. +,-,*,/) - occurs multiple times within
it.
*
* Modular reductions resolve this issue. Although an individual
modular reduction takes more time
* then an individual division, when performed in succession (with the
same modulo), they're a lot faster.
*
* The two most commonly used modular reductions are Barrett and
Montgomery reduction. Montgomery reduction,
* although faster, only works when the gcd of the modulo and of the
base being used is 1. In RSA, when the
* base is a power of two, the modulo - a product of two primes - is
always going to have a gcd of 1 (because
* the product of two odd numbers is odd), but what about when RSA
isn't used?
*
* In contrast, Barrett reduction has no such constraint. As such,
some bigint implementations perform a
* Barrett reduction after every operation in the modpow function.
Others perform Barrett reductions when the
* modulo is even and Montgomery reductions when the modulo is odd.
BigInteger.java's modPow method, however,
* uses a trick involving the Chinese Remainder Theorem to factor the
even modulo into two numbers - one odd and
* the other, a power of two - and recombine them, later. This is the
method that this modPow function uses.
* {@link http://islab.oregonstate.edu/papers/j34monex.pdf Montgomery
Reduction with Even Modulus} elaborates.

that x (mod m) = x' (mod m), with x' being smaller than x."
*
* Unfortunately, the "Barrett Reduction with Folding"
algorithm described in thesis-149.pdf is not, as written, all that

discussed in
* {@link http://math.libtomcrypt.com/files/tommath.pdf#page=162 MPM

* radix points, it only works when there are an even number of digits

they're the same, but if x is odd, they're not. See the in-line

* As for why we do all the bitmasking... strange things can happen
when converting from floats to ints. For
* instance, on some computers, var_dump((int) -4294967297) yields
int(-1) and on others, it yields
* int(-2147483648). To avoid problems stemming from this, we use
bitmasks to guarantee that ints aren't
* auto-converted to floats. The outermost bitmask is present because
without it, there's no guarantee that
* the "residue" returned would be the so-called "common
residue". We use fmod, in the last step, because the
* maximum possible $x is 26 bits and the maximum $result is 16 bits.
Thus, we have to be able to handle up to
* 40 bits, which only 64-bit floating points will support.

A Note on SFTPv4/5/6 support:
<http://tools.ietf.org/html/draft-ietf-secsh-filexfer-13#section-5.1>
states the following:
"If the client wishes to interoperate with servers that
support noncontiguous version
numbers it SHOULD send '3'"
Given that the server only sends its version number after the
client has already done so, the above
seems to be suggesting that v3 should be the default version.
This makes sense given that v3 is the
most popular.
<http://tools.ietf.org/html/draft-ietf-secsh-filexfer-13#section-5.5>
states the following;
"If the server did not send the "versions"
extension, or the version-from-list was not included, the
server MAY send a status response describing the failure, but
MUST then close the channel without
processing any further requests."
So what do you do if you have a client whose initial SSH_FXP_INIT
packet says it implements v3 and
a server whose initial SSH_FXP_VERSION reply says it implements v4
and only v4? If it only implements
v4, the "versions" extension is likely not going to have
been sent so version re-negotiation as discussed
in draft-ietf-secsh-filexfer-13 would be quite impossible. As
such, what \phpseclib3\Net\SFTP would do is close the
channel and reopen it with a new and updated SSH_FXP_INIT packet.

however, I'm not sure what 'newline@vandyke.com' is
supposed to do (the fact that it's unofficial means that it's
not in the official SFTPv3 specs) and
'newline@vandyke.com' / 'newline' are likely not
drop-in substitutes for
one another due to the fact that 'newline' comes with a
SSH_FXF_TEXT bitmask whereas it seems unlikely that
'newline@vandyke.com' would.

/**
* Uploads a file to the SFTP server.
*
* By default, \phpseclib3\Net\SFTP::put() does not read from the local
filesystem. $data is dumped directly into $remote_file.
* So, for example, if you set $data to 'filename.ext' and
then do \phpseclib3\Net\SFTP::get(), you will get a file, twelve bytes
* long, containing 'filename.ext' as its contents.
*
* Setting $mode to self::SOURCE_LOCAL_FILE will change the above
behavior. With self::SOURCE_LOCAL_FILE, $remote_file will
* contain as many bytes as filename.ext does on your local filesystem.
If your filename.ext is 1MB then that is how
* large $remote_file will be, as well.
*
* Setting $mode to self::SOURCE_CALLBACK will use $data as callback
function, which gets only one parameter -- number
* of bytes to return, and returns a string if there is some data or
null if there is no more data
*
* If $data is a resource then it'll be used as a resource
instead.
*
* Currently, only binary mode is supported. As such, if the line
endings need to be adjusted, you will need to take
* care of that, yourself.
*
* $mode can take an additional two parameters - self::RESUME and
self::RESUME_START. These are bitwise AND'd with
* $mode. So if you want to resume upload of a 300mb file on the local
file system you'd set $mode to the following:
*
* self::SOURCE_LOCAL_FILE | self::RESUME
*
* If you wanted to simply append the full contents of a local file to
the full contents of a remote file you'd replace
* self::RESUME with self::RESUME_START.
*
* If $mode & (self::RESUME | self::RESUME_START) then
self::RESUME_START will be assumed.
*
* $start and $local_start give you more fine grained control over this
process and take precident over self::RESUME
* when they're non-negative. ie. $start could let you write at
the end of a file (like self::RESUME) or in the middle
* of one. $local_start could let you start your reading from the end
of a file (like self::RESUME_START) or in the
* middle of one.
*
* Setting $local_start to > 0 or $mode | self::RESUME_START
doesn't do anything unless $mode | self::SOURCE_LOCAL_FILE.
