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.
