# Constant-Time Encoding
[![Build Status](https://github.com/paragonie/constant_time_encoding/actions/workflows/ci.yml/badge.svg)](https://github.com/paragonie/constant_time_encoding/actions)
[![Latest Stable Version](https://poser.pugx.org/paragonie/constant_time_encoding/v/stable)](https://packagist.org/packages/paragonie/constant_time_encoding)
[![Latest Unstable Version](https://poser.pugx.org/paragonie/constant_time_encoding/v/unstable)](https://packagist.org/packages/paragonie/constant_time_encoding)
[![License](https://poser.pugx.org/paragonie/constant_time_encoding/license)](https://packagist.org/packages/paragonie/constant_time_encoding)
[![Downloads](https://img.shields.io/packagist/dt/paragonie/constant_time_encoding.svg)](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====
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).

/**
* Pure-PHP implementation of AES.
*
* Uses mcrypt, if available/possible, and an internal implementation, otherwise.
*
* PHP version 5
*
* NOTE: Since AES.php is (for compatibility and phpseclib-historical reasons) virtually
* just a wrapper to Rijndael.php you may consider using Rijndael.php instead of
* to save one include_once().
*
* 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.
*
* Since \phpseclib3\Crypt\AES extends \phpseclib3\Crypt\Rijndael, some functions are available to be called that, in the context of AES, don't
* make a whole lot of sense. {@link self::setBlockLength() setBlockLength()}, for instance. Calling that function,
* however possible, won't do anything (AES has a fixed block length whereas Rijndael has a variable one).
*
* Here's a short example of how to use this library:
* <code>
* <?php
* include 'vendor/autoload.php';
*
* $aes = new \phpseclib3\Crypt\AES('ctr');
*
* $aes->setKey('abcdefghijklmnop');
*
* $size = 10 * 1024;
* $plaintext = '';
* for ($i = 0; $i < $size; $i++) {
* $plaintext.= 'a';
* }
*
* echo $aes->decrypt($aes->encrypt($plaintext));
* ?>

/**
* 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:
*
* https://github.com/openssh/openssh-portable/blob/master/openbsd-compat/bcrypt_pbkdf.c
*
* Here's a short example of how to use this library:
* <code>
* <?php
* include 'vendor/autoload.php';
*
* $blowfish = new \phpseclib3\Crypt\Blowfish('ctr');
*
* $blowfish->setKey('12345678901234567890123456789012');
*
* $plaintext = str_repeat('a', 1024);
*
* echo $blowfish->decrypt($blowfish->encrypt($plaintext));
* ?>
* </code>

"outside the scope" of PKCS#1. PKCS#1 then refers you to PKCS#12 and PKCS#15 if you're wanting to
protect private keys, however, that's not what OpenSSL* does. OpenSSL protects private keys by adding
two new "fields" to the key - DEK-Info and Proc-Type. These fields are discussed here:
http://tools.ietf.org/html/rfc1421#section-4.6.1.1
http://tools.ietf.org/html/rfc1421#section-4.6.1.3
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.
