PHP 5.x polyfill for mcrypt extension.
With Composer:
composer require phpseclib/mcrypt_compat
- rijndael-128
- rijndael-192
- rijndael-256
- blowfish-compat
- des
- blowfish
- rc2
- tripledes
- arcfour
- cast-128
- gost
- cast-256
- loki97
- saferplus
- wake
- serpent
- xtea
- enigma
- cbc
- ncfb
- ctr
- ecb
- nofb
- stream
Although ncfb and nofb are supported cfb and ofb are not. Further, mcrypt_compat's ncfb implementation has some incompatibles with mcrypt's implementation where mcrypt_generic and mdecrypt_generic are concerned. The unit tests elaborate.
