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.
