NAME

shishi_pbkdf2_sha1 - API function

SYNOPSIS

#include <shishi.h>

int shishi_pbkdf2_sha1(Shishi * handle, const char * P, size_t Plen, const char * S, size_t Slen, unsigned int c, unsigned int dkLen, char * DK);

ARGUMENTS

Shishi * handle: shishi handle as allocated by shishi_init().
const char * P: input password, an octet string
size_t Plen: length of password, an octet string
const char * S: input salt, an octet string
size_t Slen: length of salt, an octet string
unsigned int c: iteration count, a positive integer
unsigned int dkLen: intended length in octets of the derived key, a positive integer, at most (2^32 - 1) * hLen. The DK array must have room for this many characters.
char * DK: output derived key, a dkLen-octet string

DESCRIPTION

Derive key using the PBKDF2 defined in PKCS5. PBKDF2 applies a pseudorandom function to derive keys. The length of the derived key is essentially unbounded. (However, the maximum effective search space for the derived key may be limited by the structure of the underlying pseudorandom function, which is this function is always SHA1.)

RETURN VALUE

Returns SHISHI_OK iff successful.
