Serpent was designed by Ross Anderson, Eli Biham and Lars Knudsen as a candidate for the Advanced Encryption Standard. It has been selected as one of the five finalists in the AES competition. Serpent is faster than DES and more secure than Triple DES. It provides users with a very high level of assurance that no shortcut attack will be found. To achieve this, the algorithm's designers limited themselves to well understood cryptography mechanisms, so that they could rely on the wide experience and proven techniques of block cipher cryptanalysis. The algorithm uses twice as many rounds as are necessary to block all currently known shortcut attacks. This means that Serpent should be safe against as yet unknown attacks that may be capable of breaking the standard 16 rounds used in many types of encryption today. However, the fact that Serpent uses so many rounds means that it is the slowest of the five AES finalists. But this shouldn't be an issue because it still outperforms Triple DES. The algorithm's designers maintain that Serpent has a service life of at least a century.

This module implements the twofish cipher in a less braindamaged (read: slow and ugly) way than the existing "Crypt::Twofish" module. Although it is "Crypt::CBC" compliant you usually gain nothing by using that module (except generality), since "Crypt::Twofish2" can work in either ECB or CBC mode.

The chrootuid command combines chroot(8) and su(1) into one program, so that there is no need to have commands such as /usr/bin/su in the restricted environment. Access to the file system is restricted to the newroot subtree and privileges are restricted to those of the newuser account (which must be a known account in the unrestricted environment). See also jail(8)

Clamassassin is a simple virus filter wrapper for ClamAV for use in procmail filters and similiar applications. Clamassassin's interface is similiar to that of spamassassin, making it easy to implement for those familiar with that tool. Clamassassin is designed with an emphasis on security, robustness and simplicity.

Network Security Services (NSS) is a set of libraries designed to support cross-platform development of security-enabled server applications. Applications built with NSS can support SSL v2 and v3, TLS, PKCS #5, PKCS #7, PKCS #11, PKCS #12, S/MIME, X.509 v3 certificates, and other security standards.

MD5 sums (see RFC 1321 - The MD5 Message-Digest Algorithm) are used as a one-way hash of data. Due to the nature of the formula used, it is impossible to reverse it. This module provides functions to search several online MD5 hashes database and return the results (or return undefined if no match found).

Digest::Pearson::PurePerl is an implementation of Peter K. Pearson's hash algorithm presented in "Fast Hashing of Variable Length Text Strings" - ACM 1990. This hashing technique yields good distribution of hashed results for variable length input strings on the range 0-255, and thus, it is well suited for data load balancing. If you prefer a fast implementation, you might want to consider Digest::Pearson instead.

This is not C-code interface (like `Digest::MD5') but a Perl-only implementation of MD4 (like `Digest::Perl::MD5'). Because of this, it is slow but avoids platform specific complications. For efficiency you should use `Digest::MD4' instead of this module if it is available.

Dancer::Plugin::Passphrase manages the hashing of passwords for Dancer apps, allowing developers to follow cryptography best practices without having to become a cryptography expert. It uses the bcrypt algorithm as the default, while also supporting any hashing function provided by Digest.

Dancer2::Plugin::Passphrase manages the hashing of passwords for Dancer apps, allowing developers to follow cryptography best practices without having to become a cryptography expert. It uses the bcrypt algorithm as the default, while also supporting any hashing function provided by Digest.
