CRYPTO_CIPHER_SETKEY(9) Programming Interface CRYPTO_CIPHER_SETKEY(9)
NAME
crypto_cipher_setkey - set key for cipher
SYNOPSIS
int crypto_cipher_setkey(struct crypto_cipher * tfm, const u8 * key, unsigned int keylen);
ARGUMENTS
tfm
cipher handle
key
buffer holding the key
keylen
length of the key in bytes
DESCRIPTION
The caller provided key is set for the single block cipher referenced by the cipher
handle.
Note, the key length determines the cipher type. Many block ciphers implement different
cipher modes depending on the key size, such as AES-128 vs AES-192 vs. AES-256. When
providing a 16 byte key for an AES cipher handle, AES-128 is performed.
RETURN
0 if the setting of the key was successful; < 0 if an error occurred
