# 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:
|
||||
|
||||
```

||||

|
||||
```
|
||||
|
||||
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:
|
||||
|
||||
```
|
||||

|
||||

|
||||
```
|
||||

||||

* 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.

two new "fields" to the key - DEK-Info and Proc-Type. These fields are discussed here:

DES-EDE3-CBC as an algorithm, however, is not discussed anywhere, near as I can tell.

DES-CBC and DES-EDE are discussed in RFC1423, however, 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

implementation are part of the standard, as well.

* 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
|
||||
* new method for those. eg. KoblitzA1Prime.php or something.

|

* http://www.secg.org/SEC2-Ver-1.0.pdf provides for curves with custom parameters.
|

* ie. the coefficients can be arbitrary set through specially formatted keys, etc.
|

* As such, Prime.php is built very generically and it's not able to take full

* advantage of curves with 0 coefficients to produce simplified point doubling,
|

* point addition. Twisted Edwards curves, in contrast, do not have a way, currently,
|

* to customize them. As such, we can omit the super generic stuff from this class
|

* and let the named curves (Ed25519 and Ed448) define their own custom tailored
|

* point addition and point doubling methods.

|

* slightly optimized. See http://hyperelliptic.org/EFD/g1p/auto-shortw-projective-3.html
