SYNOPSIS¶

#include <shishi.h>

int shishi_checksum(Shishi * handle, Shishi_key * key, int keyusage, int cksumtype, const char * in, size_t inlen, char ** out, size_t * outlen);

ARGUMENTS¶

Shishi * handle

shishi handle as allocated by shishi_init().

Shishi_key * key

key to compute checksum with.

int keyusage

integer specifying what this key is used for.

int cksumtype

the checksum algorithm to use.

const char * in

input array with data to integrity protect.

size_t inlen

size of input array with data to integrity protect.

char ** out

output array with newly allocated integrity protected data.

size_t * outlen

output variable with length of output array with checksum.
