NAME
Crypt::OpenPGP::Util - Miscellaneous utility functions

DESCRIPTION
Crypt::OpenPGP::Util contains a set of exportable utility functions used through the Crypt::OpenPGP set of libraries.

  bitsize($n)
Returns the number of bits in the Math::BigInt integer object $n.

  bin2bigint($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::BigInt object.

bin2mp is an alias for this function, for backwards compatibility reasons.

  bigint2bin($int)
Given a biginteger $int (a Math::BigInt object), linearizes the integer into an octet string, and returns the octet string.

mp2bin is an alias for this function, for backwards compatibility reasons.

  mod_exp($a, $exp, $n)
Computes $a ^ $exp mod $n and returns the value. The calculations are done using Math::BigInt, and the return value is a Math::BigInt object.

  mod_inverse($a, $n)
Computes the multiplicative inverse of $a mod $n and returns the value. The calculations are done using Math::BigInt, and the return value is a Math::BigInt object.

  canonical_text($text)
Takes a piece of text content $text and formats it into PGP canonical text, where: 1) all whitespace at the end of lines is stripped, and 2) all line endings are made up of a carriage return followed by a line feed. Returns the canonical form of the text.

  dash_escape($text)
Escapes $text for use in a cleartext signature; the escaping looks for any line starting with a dash, and on such lines prepends a dash ('-') followed by a space (' '). Returns the escaped text.
