NAME
Crypt::KDF::BaseKDFGenerator - Basic KDF generator for derived keys and ivs as defined by IEEE P1363a/ISO 18033.
SYNOPSIS
DESCRIPTION
This implementation is based on ISO 18033/P1363a.
FUNCTIONS
$derivedKey = baseKdf_generate( $digest, $seed, $counter, $len )
Quick functional interface to use KDF.
METHODS
$kdf = Crypt::KDF::BaseKDFGenerator->new( [options] )
Construct a Basic KDF generator.
-counter start value of counter used to derive keys.
-digest the digest to be used as the source of derived keys.
-digestparam optional parameters for the digest used to derive keys.
-seed the seed to be used to derive keys.
-iv optional iv to be used to derive keys.$kdf->init( [options] )
Initialize the Basic KDF generator.
-counter start value of counter used to derive keys.
-digest the digest to be used as the source of derived keys.
-digestparam optional parameters for the digest used to derive keys.
-seed the seed to be used to derive keys.
-iv optional iv to be used to derive keys.$derivedKey = $kdf->kdf( $length )
Return length bytes generated from the derivation function.
( $derivedKey, $derivedIV ) = $kdf->kdf_iv( $kLen, $ivLen )
Return length bytes generated from the derivation function.
