Integrity checkers that support MD5 seems to be preferable as MD5 checksums are often available from vendors. Perl implementations are generally more fle xible that written in C.

Alternatives to Tripwire:.

AIDE (Advanced Intrusion Detection Environment) is a free replacement for Tripwire(tm). It is probably one of the most popular replacements. It generates a database that can be used to check the integrity of files on server. It uses regular expressions for determining which files get added to the database. You can use several message digest algorithms to ensure that the files have not been tampered with.
SourceForge Project Info - integrit file verification system
integrit is a simple yet secure alternative to products like tripwire. It has a small memory footprint, uses up-to-date cryptographic algorithms, and has features that make sense (like including the MD5 checksum of newly generated databases in the report)

Nannie's basic purpose is to watch system files that should not be changed, at least in theory. It monitors them for change in inode, size, etc. and logs them to syslog.
Binaudit performs a similar function to Tripwire - it maintains a database of the binaries on the system and an associated checksum-based 'signature'. Frequent testing of the system against the database will reveal any changes (whether authorised or not). This is a network-oriented file system auditing tool. It allows you to generate master checklists and compare the state of the file system to the state captured in this list; changes (additions, deletions, modifications) are reported. It is designed to work on many hosts serially, and has options for collapsing the output into a single mail message, as well as the ability to do cryptographic checksumming, and to ignore files, directories, subtrees of the file hierarchy, and specific characteristics of any of those.

The Shmoo Group - Osiris Scripts Implementation language - C. Uses gdb, Tested on Solaris. Looks like one of the most developed free packages.
The Osiris application compares one catalog of executable files with another catalog of executable files. Osiris catalogs specified directories of files (including hashes ( currently MD5 ), modification dates, file attributes, uid, gid, and suid into a specified database (and/or to STDOUT as directed). The second program, scale, compares two such databases against each other. It will output, either to a file or STDOUT, any differences it finds between the two catalogs (including missing or additional files, differing or same hashes, modification dates, and file attributes). Together, the two programs give an administrator the tools to follow changes in files on a server or workstation. This keeps an administrator apprised of possible attacks and/or nasty little trojans, and is the main reason for the existence of Osiris.
Main language - C; Uses gdb, Tested on Solaris. Looks like one of the most developed free packages.
