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
