mcrypt_cbc

Encrypts/decrypts data in CBC mode

&reftitle.description; `string` `mcrypt_cbc` `int` `cipher` `string` `key` `string` `data` `int` `mode` `string` `iv` `string` `mcrypt_cbc` `string` `cipher` `string` `key` `string` `data` `int` `mode` `string` `iv`

The first prototype is when linked against libmcrypt 2.2.x, the second when linked against libmcrypt 2.4.x or higher. The `mode` should be either `MCRYPT_ENCRYPT` or `MCRYPT_DECRYPT`.

This function should not be used anymore, see `mcrypt_generic` and `mdecrypt_generic` for replacements.
