NAME

       kcapi_cipher_setkey - set the key for the cipher handle

SYNOPSIS

       int kcapi_cipher_setkey(struct kcapi_handle * handle, const uint8_t * key,
                               uint32_t keylen);

ARGUMENTS

       handle
           [in] cipher handle

       key
           [in] key buffer

       keylen
           [in] length of key buffer

DESCRIPTION

       With this function, the caller sets the key for subsequent encryption or decryption
       operations.

       After the caller provided the key, the caller may securely destroy the key as it is now
       maintained by the kernel.

       return 0 upon success (in case of an akcipher handle, a positive integer is returned that
       denominates the maximum output size of the cryptographic operation -- this value must be
       used as the size of the output buffer for one cryptographic operation); a negative
       errno-style error code if an error occurred
