NAME¶
Crypt::DSA::Util - DSA Utility functions
SYNOPSIS¶
use Crypt::DSA::Util qw( func1 func2 ... );
DESCRIPTION¶
Crypt::DSA::Util contains a set of exportable utility functions used
through the
Crypt::DSA set of libraries.
bitsize($n)¶
Returns the number of bits in the
Math::Pari integer object
$n .
bin2mp($string)¶
Given a string
$string of any length, treats the string as
a base-256 representation of an integer, and returns that integer, a
Math::Pari object.
mp2bin($int)¶
Given a biginteger
$int (a
Math::Pari object),
linearizes the integer into an octet string, and returns the octet string.
mod_exp($a, $exp, $n)¶
Computes $a ^ $exp mod $n and returns the value. The calculations are done using
Math::Pari, and the return value is a
Math::Pari object.
mod_inverse($a, $n)¶
Computes the multiplicative inverse of $a mod $n and returns the value. The
calculations are done using
Math::Pari, and the return value is a
Math::Pari object.
