- 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 using the IV set by the caller with a preceding call of crypto_blkcipher_set_iv.
