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.
