PostfixAdmin\\PasswordHashing
=============================

[](#postfixadminpasswordhashing)

Standalone PHP library for creating various password hashes

Note, this library is still quite new (2021/07/02). It's quite likely to have major refactoring / renaming as it's reviewed.

Supported Mechanisms (hash formats)
-----------------------------------

[](#supported-mechanisms-hash-formats)

See:

 [pacrypt/src/Crypt.php](https://github.com/postfixadmin/pacrypt/blob/46ddd21a28433faa8ea279e4161f7853a69b40cb/src/Crypt.php#L12)

 Line 12 in [46ddd21](/postfixadmin/pacrypt/commit/46ddd21a28433faa8ea279e4161f7853a69b40cb)

     public const SUPPORTED = \[

Some mechanisms support either HEX (.HEX) encoded or BASE64 (.B64) encoded output.

Currently:

- SHA1, SHA1.HEX, SHA1.B64
- SSHA
- SSHA512
- BLF-CRYPT, BLF-CRYPT.B64
- SHA512-CRYPT, SHA512-CRYPT.B64
- ARGON2I, ARGON2I.B64
- ARGON2ID, ARGON2ID.B64
- SHA256, SHA256-CRYPT, SHA256-CRYPT.B64
- SHA512, SHA512.B64
- MD5-CRYPT, MD5
- PLAIN-MD5
- CRYPT ({CRYPT} prefix, defaults to use Blowfish)
- SYSTEM (DES CRYPT, best avoid)
- PLAIN, CLEAR, CLEARTEXT (useful for testing)
- COURIER:MD5
- COURIER:MD5RAW
- COURIER:SSHA (same as SSHA)
- COURIER:SHA256 (same as SHA256)

Example usage
-------------

[](#example-usage)

The main functionality reflects legacy behaviour in PostfixAdmin with a 'pacrypt' function, which when given ...

- one argument - clear text password - returns a hash.
- two arguments - clear text password and stored hash - if the return value matches the stored hash, then the clear text password was a match for the hash we have.

```
$tool = new \PostfixAdmin\PasswordHashing\Crypt('ARGON2I');

// should output something to indicate what your system supports (may be dependent on PHP variant, PHP modules etc)

$hash = $tool->crypt('fishbeans');

echo "Hash is: $hash \n";

echo "Verify: " . json_encode($hash == $tool->crypt('fishbeans', $hash)) . "\n";
echo "Verify fails with: " . json_encode('cat' == $tool->crypt('fishbeans', $hash)) . "\n";
```

the above code will output something similar to:

```
Hash is: {ARGON2I}$argon2i$v=19$m=65536,t=4,p=1$d1JMUXVHSUtLTGhxYnowVQ$4raz6DDUbtRysi+1ZTdNL3L5j4tcSYnzWxyLVDtFjKc
Verify: true
Verify fails with: false

```
