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
           reference to the aead_request handle that holds all information needed to perform the
           cipher operation

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
