struct scatterlist * src,
unsigned int nbytes);
ARGUMENTS¶
descreference 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.
