A perl module that implements the tiger hash, which is believed to be secure
and runs quickly on 64-bit processors.
This perl module provides support for the https protocol
under LWP, so that a LWP::UserAgent can make https GET &
HEAD & POST requests. Please see perldoc LWP for more
information on POST requests.
The Crypt::SSLeay package contains Net::SSL, which is
automatically loaded by LWP::Protocol::https on https
requests, and provides the necessary SSL glue for that
module to work via these deprecated modules:
Crypt::SSLeay::CTX
Crypt::SSLeay::Conn
Crypt::SSLeay::X509
Work on Crypt::SSLeay has been continued only to provide
https support for the LWP - libwww perl libraries. If you
want access to the OpenSSL API via perl, check out Sampo's
Net::SSLeay.
This module gives access to the routines of the GSSAPI library,
as described in rfc2743 and rfc2744 and implemented by the
Kerberos-1.2 distribution from MIT.

Digest::SHA is a complete implementation of the NIST Secure Hash
Standard. It gives Perl programmers a convenient way to calculate
SHA-1, SHA-224, SHA-256, SHA-384, and SHA-512 message digests. The
module can handle all types of input, including partial-byte data.
This module maintains a concept of a current selection of entropy
source. Algorithms that require entropy can use the source nominated
by this module, avoiding the need for entropy source objects to be
explicitly passed around. This is convenient because usually one
entropy source will be used for an entire program run and so an
explicit entropy source parameter would rarely vary. There is also a
default entropy source, avoiding the need to explicitly configure a
source at all.
If nothing is done to set a source then it defaults to the use of
Rijndael (AES) in counter mode (see
Data::Entropy::RawSource::CryptCounter and Crypt::Rijndael), keyed
using Perl's built-in rand function. This gives a data stream that
looks like concentrated entropy, but really only has at most the
entropy of the rand seed. Within a single run it is cryptographically
difficult to detect the correlation between parts of the
pseudo-entropy stream. If more true entropy is required then it is
necessary to configure a different entropy source.
Heimdal::Kadm5 is a Perl XS wrapper around the Heimdal Kerberos
administrative client library (libkadm5clnt). Heimdal is a free slightly
less export challenged implementation of Kerberos5 by Assar Westerlund and
Johan Danielsson. This module exposes the API used to administer a
Kerberos realm: add, remove, and list principals, create keytabs, change
keys, and similar operations.
The Digest::Adler32 module implements the Adler-32 checksum as specified
in RFC 1950. The interface provided by this module is specified in Digest,
but no functional interface is provided.
The Digest::CRC module calculates CRC sums of all sorts. It contains wrapper
functions with the correct parameters for CRC-CCITT, CRC-16 and CRC-32.
Digest::BubbleBabble takes a message digest (generated by
either of the MD5 or SHA-1 message digest algorithms) and creates
a fingerprint of that digest in "bubble babble" format.
Bubble babble is a method of representing a message digest
as a string of "real" words, to make the fingerprint easier
to remember. The "words" are not necessarily real words, but
they look more like words than a string of hex characters.
Bubble babble fingerprinting is used by the SSH2 suite
(and, consequently, by Net::SSH::Perl, the Perl SSH
implementation) to display easy-to-remember key fingerprints.
The key (a DSA or RSA key) is converted into a textual form,
digested using Digest::SHA1, and run through bubblebabble
to create the key fingerprint.
