CRYPTO_AEAD_SETKEY(9)                 Programming Interface                 CRYPTO_AEAD_SETKEY(9)



NAME
       crypto_aead_setkey - set key for cipher

SYNOPSIS
       int crypto_aead_setkey(struct crypto_aead * 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 AEAD 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
