CRYPTO_BLKCIPHER_ENC(9)               Programming Interface               CRYPTO_BLKCIPHER_ENC(9)



NAME
       crypto_blkcipher_encrypt_iv - encrypt plaintext with dedicated IV

SYNOPSIS
       int crypto_blkcipher_encrypt_iv(struct blkcipher_desc * desc, struct scatterlist * dst,
                                       struct scatterlist * src, unsigned int nbytes);

ARGUMENTS
       desc
           reference to the block cipher handle with meta data

       dst
           scatter/gather list that is filled by the cipher operation with the ciphertext

       src
           scatter/gather list that holds the plaintext

       nbytes
           number of bytes of the plaintext to encrypt.

DESCRIPTION
       Encrypt plaintext data with the use of an IV that is solely used for this cipher
       operation. Any previously set IV is not used.

       The blkcipher_desc data structure must be filled by the caller and can reside on the
       stack. The caller must fill desc as follows: desc.tfm is filled with the block cipher
       handle; desc.info is filled with the IV to be used for the current operation; desc.flags
       is filled with either CRYPTO_TFM_REQ_MAY_SLEEP or 0.

RETURN
       0 if the cipher operation was successful; < 0 if an error occurred
