CRYPTO_BLKCIPHER_ENC(9)               Programming Interface               CRYPTO_BLKCIPHER_ENC(9)



NAME
       crypto_blkcipher_encrypt - encrypt plaintext

SYNOPSIS
       int crypto_blkcipher_encrypt(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 using the IV set by the caller with a preceding call of
       crypto_blkcipher_set_iv.

       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.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
