CRYPTO_AEAD_ENCRYPT(9) | Programming Interface | CRYPTO_AEAD_ENCRYPT(9) |
NAME¶
crypto_aead_encrypt - encrypt plaintext
SYNOPSIS¶
int crypto_aead_encrypt(struct aead_request * req);
ARGUMENTS¶
req
DESCRIPTION¶
Encrypt plaintext data using the aead_request handle. That data structure and how it is filled with data is discussed with the aead_request_* functions.
IMPORTANT NOTE The encryption operation creates the authentication data / tag. That data is concatenated with the created ciphertext. The ciphertext memory size is therefore the given number of block cipher blocks + the size defined by the crypto_aead_setauthsize invocation. The caller must ensure that sufficient memory is available for the ciphertext and the authentication tag.
RETURN¶
0 if the cipher operation was successful; < 0 if an error occurred
