This package is a Perl interface to famous library PARI for
numerical/scientific/number-theoretic calculations. It allows use of
most PARI functions as Perl functions, and (almost) seamless merging of
PARI and Perl data. In what follows we suppose prior knowledge of what
PARI is (see <ftp://megrez.math.u-bordeaux.fr/pub/pari>, or
Math::libPARI).

The PARI system is a package which is capable of doing formal
computations on recursive types at high speed; it is primarily
aimed at number theorists, but can be used by anybody whose primary
need is speed.
It is possible to use PARI in two different ways:
1) as a library, which can be called from an upper-level language
application (for instance written in C, C++, Pascal or Fortran);
2) as a sophisticated programmable calculator, named gp, which
contains most of the control instructions of a standard language
like C.

Sort::Versions allows easy sorting of mixed non-numeric and numeric strings,
like the 'version numbers' that many shared library systems and revision
control packages use. This is quite useful if you are trying to deal with
shared libraries. It can also be applied to applications that intersperse
variable-width numeric fields within text. Other applications can
undoubtedly be found.
Convert::PEM reads and writes PEM files containing ASN.1-encoded
objects. The files can optionally be encrypted using a symmetric
cipher algorithm, such as 3DES.
This module converts hashes of binary octets into ASCII messages suitable
for transfer over 6-bit clean transport channels. The encoded ASCII
resembles PGP's armoured messages, but are in no way compatible with PGP.
Tie::EncryptedHash augments Perl hash semantics to build secure, encrypting
containers of data. Tie::EncryptedHash introduces special hash fields that
are coupled with encrypt/decrypt routines to encrypt assignments at STORE()
and decrypt retrievals at FETCH().
Crypt::DES_EDE3 implements DES-EDE3 encryption. This is triple-DES
encryption where an encrypt operation is encrypt-decrypt-encrypt, and
decrypt is decrypt-encrypt-decrypt. This implementation uses Crypt::DES
to do its dirty DES work, and simply provides a wrapper around that
module: setting up the individual DES ciphers, initializing the keys,
and performing the encryption/decryption steps.
