lib-crypt

Shorthand library for using AES encryption provided by PHP-Mcrypt, (*1)

Usage

use \LSS\Crypt;

//create keys
$iv_key = Crypt::IVCreate();
$crypt_key = Crypt::keyCreate();

$crypt = Crypt::_get($crypt_key,$iv_key);
$crypted_str = $crypt->encrypt('my string'); //returns base64 encoded crypted string
$var = $crypt->decrypt($crypted_str); //returns 'my string'

Padding

By default MCrypt will NULL-PAD strings to get the proper encryption. However this creates problems when expecting exact payload encryption (such as binary), (*2)

Crypt deals with this by storing the size of the payload as the first 4 bytes in the returned string Crypt then extracts this size and trims the payload to the original size upon decrypt, (*3)

The downside to this is that it cant be decrypted by the regular MCrypt functions without first stripping the initial 4 bytes. It would be recommended to trim the payload if possible, (*4)

Reference

(string) Crypt::IVCreate()

Returns a proper initialization vector for the encryption type, (*5)

(string) Crypt::keyCreate()

Returns a proper secret key for the encryption type, (*6)

(object) Crypt::_get($key,$iv)

Shorthand for the construct that returns the new object, (*7)

(object) Crypt::setKey($key)

Change the key at runtime Returns $this so its chainable, (*8)

(object) Crypt::setIV($iv)

Change the IV at runtime Returns $this so its chainable, (*9)

(object) Crypt::verify()

Verifies the key and IV Will throw exceptions on errors Returns $this so its chainable, (*10)

(string) Crypt::encrypt($plain_string,$base64_encode=true)

  • $plain_string String to be encrypted
  • $base64_encode TRUE to base64_encode the encrypted string Returns the encrypted and optionally base64_encoded string

(string) Crypt::decrypt($enc_string,$base64_decode=true)

  • $enc_string The encrypted string to be decrypted
  • $base64_decode If the $enc_string is base64_encoded set to TRUE Returns the EXACT original string
