crypto_blkcipher_encrypt: encrypt plaintext

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
