The RC5 encryption algorithm for EVP.
EVP_rc5_32_12_16_ofb()
RC5 encryption algorithm in CBC, CFB, ECB and OFB modes respectively. This is a variable key length cipher with an additional ``number of rounds'' parameter. By default the key length is set to 128 bits and 12 rounds. Alternative key lengths can be set using EVP_CIPHER_CTX_set_key_length(3). The maximum key length is 2040 bits.
The following rc5 specific ctrls are supported (see EVP_CIPHER_CTX_ctrl(3)).
Sets the number of rounds to rounds. This must be one of RC5_8_ROUNDS, RC5_12_ROUNDS or RC5_16_ROUNDS.
Stores the number of rounds currently configured in *rounds where *rounds is an int.
These functions return an EVP_CIPHER structure that contains the implementation of the symmetric cipher. See EVP_CIPHER_meth_new(3) for details of the EVP_CIPHER structure.
