shishi_checksum(3) API function


#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);


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.


Integrity protect data using key, possibly altered by supplied key usage. If key usage is 0, no key derivation is used. The OUT buffer must be deallocated by the caller.


Returns SHISHI_OK iff successful.
