mcrypt_ofb

(PHP3 >= 3.0.8, PHP4 )

mcrypt_ofb -- Encrypt/decrypt data in OFB mode

Description

string mcrypt_ofb (int cipher, string key, string data, int mode, string iv)

string mcrypt_ofb (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.

Mcrypt_ofb() encrypts or decrypts (depending on mode) the data with cipher and key in OFB cipher mode and returns the resulting string.

Cipher is one of the MCRYPT_ciphername constants.

Key is the key supplied to the algorithm. It must be kept secret.

Data is the data which shall be encrypted/decrypted.

Mode is MCRYPT_ENCRYPT or MCRYPT_DECRYPT.

IV is the initialization vector.

See also: mcrypt_cbc(), mcrypt_cfb(), and mcrypt_ecb().
