SKCIPHER_REQUEST_SET(9) Programming Interface SKCIPHER_REQUEST_SET(9)

NAME

skcipher_request_set_crypt - set data buffers

SYNOPSIS

void skcipher_request_set_crypt(struct skcipher_request * req, struct scatterlist * src, struct scatterlist * dst, unsigned int cryptlen, void * iv);

ARGUMENTS

req

request handle

src

source scatter / gather list

dst

destination scatter / gather list

cryptlen

number of bytes to process from src

iv

IV for the cipher operation which must comply with the IV size defined by crypto_skcipher_ivsize

DESCRIPTION

This function allows setting of the source data and destination data scatter / gather lists.

For encryption, the source is treated as the plaintext and the destination is the ciphertext. For a decryption operation, the use is reversed - the source is the ciphertext and the destination is the plaintext.
