shishi_pbkdf2_sha1(3)						      shishi						     shishi_pbkdf2_sha1(3)

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.

NAME

       shishi_dk - API function

SYNOPSIS

       #include <shishi.h>

       int shishi_dk(Shishi * handle, Shishi_key * key, const char * prfconstant, size_t prfconstantlen, Shishi_key * derivedkey);

ARGUMENTS

       Shishi * handle
		   shishi handle as allocated by shishi_init().

       Shishi_key * key
		   input cryptographic key to use.

       const char * prfconstant
		   input array with the constant string.

       size_t prfconstantlen
		   size of input array with the constant string.

       Shishi_key * derivedkey
		   pointer to derived key (allocated by caller).

DERIVE A KEY FROM A KEY AND A CONSTANT THUSLY

       DK(KEY, PRFCONSTANT) = SHISHI_RANDOM-TO-KEY(SHISHI_DR(KEY, PRFCONSTANT)).

RETURN VALUE

       Returns SHISHI_OK iff successful.
