CRYPTO_BLKCIPHER_DEC(9)               Programming Interface               CRYPTO_BLKCIPHER_DEC(9)



NAME
       crypto_blkcipher_decrypt_iv - decrypt ciphertext with dedicated IV

SYNOPSIS
       int crypto_blkcipher_decrypt_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 plaintext

       src
           scatter/gather list that holds the ciphertext

       nbytes
           number of bytes of the ciphertext to decrypt.

DESCRIPTION
       Decrypt ciphertext 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 as documented for the
       crypto_blkcipher_encrypt_iv call above.

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