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
