Free md5 software for linux

This Java program creates an MD5 database of all files in a directory structure, and then allows you to easily recheck the contents of the directory and notify you if any files has changed.

It does not (currently) detect removed files. It only computes MD5 sum if the "last modified" timestamp of the file has changed since the last run, unless the -nomtime option is used.

Usage

md5i [-db ] [-v] [-nomtime] [[-updatedb] -scan ] [[-alwaysignore] -check]

Generic options:
-db FILE uses FILE to store file data (default: ~/.md5database)
-v verbose: outputs progress information
-nomtime ignore file timestamps

Scan options:
-scan DIR scans DIR and all sub-directories
-updatedb updates the database instead of creating a new

Check uptions
-check DIR checks all files in DIR and its sub-directories
-alwaysignore Dont prompt on modified files: only report and ignore

Digest::MD5::Perl is a Perl implementation of Ron Rivests MD5 Algorithm.

This is not an interface (like Digest::MD5) but a Perl implementation of MD5. It is written in perl only and because of this it is slow but it works without C-Code. You should use Digest::MD5 instead of this module if it is available. This module is only usefull for
computers where you cannot install Digest::MD5 (e.g. lack of a C-Compiler) encrypting only small amounts of data (less than one million bytes). I use it to hash passwords.

SYNOPSIS

# Functional style
use Digest::MD5 qw(md5 md5_hex md5_base64);

$hash = md5 $data;
$hash = md5_hex $data;
$hash = md5_base64 $data;


# OO style
use Digest::MD5;

$ctx = Digest::MD5->new;

$ctx->add($data);
$ctx->addfile(*FILE);

$digest = $ctx->digest;
$digest = $ctx->hexdigest;
$digest = $ctx->b64digest;

Digest::MD5::Reverse provides MD5 Reverse Lookup.
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).
We are not breaking security. We are however making it easier to lookup the source of a MD5 sum.
Version restrictions:
- It is very slow, because it will search each library until match found or all library search finished.

Fast MD5 Implementation in Java is a heavily optimized implementation of the MD5 hashing algorithm written in Java.
Fast MD5 Implementation in Java includes an optional native method for even greater speed improvements.
How Fast Is It?
Short answer:Much faster than any other Java implementation that I have tested and (surprisingly) even faster than the native, non-Java MD5 implementation on some systems.
Long answer:First of all, it is important to note that the term "fast" is used here in relative terms. The implementation of the MD5 message digest algorithm available on this page is written in Java and is fast compared with other implementations written in Java, both because it is heavily optimized by itself and because there is an optional native method that makes it even faster when the platform supports it. How it compares to a sensible implementation written in a language, such as C, that is compiled directly to machine code, is heavily dependent upon how good of a job the JIT compiler in your JVM does in compiling the code or whether you are able to use the optional native method.
Enhancements:
- Martin West contributed a bug fix and some code refactoring to make all targets work out of the box in the Ant build file. Previously, the "dist" target did not work if the "docs" directory was not present.

MiniCD is (as the name suggests) a live MiniCD Linux distribution designed to run off 185MB CDs.
This distribution features automatic hardware detection, a full desktop (KDE) and is based on Mandrake Linux.
MD5: 8531b2a64fc30c919c2129fbe79987e2 minicd-1.0-rc3.i586.iso
Enhancements:
- You have been waiting, begging for more and finally it has arrived. The new completely-bloated release features 182.2MB of goodies, still small enough to fit on those 185MB CDs you have lying around. New in this release is bugfix updates to most of the core packages, the addition of Mozilla, Mozilla-mail (with enigmail included), Mplayer, better hardware detection and much much more...

Digest::Perl::MD4 is a Perl implementation of Ron Rivests MD4 Algorithm.

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.

SYNOPSIS

# Functional style
use Digest::Perl::MD4 qw(md4 md4_hex md4_base64);

$hash = md4 $data;
$hash = md4_hex $data;
$hash = md4_base64 $data;


# OO style
use Digest::Perl::MD4;

$ctx = Digest::Perl::MD4->new;

$ctx->add($data);
$ctx->addfile(*FILE);

$digest = $ctx->digest;
$digest = $ctx->hexdigest;
$digest = $ctx->b64digest;

qmail-smtpd-auth is a patch for qmail that enables it to support SMTP AUTH protocol with the following auth types: LOGIN, PLAIN and CRAM-MD5. Its based on a previous patch by Mrs.Brisby that implemented LOGIN type. This version has some enhancements and allows easy adding of new auth methods.
If you want to learn more about SMTP AUTH itself, then visit my SMTP AUTH page.
This patch adds the ESMTP AUTH option to qmail-1.03, allowing the LOGIN, PLAIN, and CRAM-MD5 AUTH types. An appropriate checkpassword tool is necessary to support the authentication. See http://cr.yp.to/checkpwd.html for more information on the interface. Note that the checkpassword tool should support all of the AUTH types
advertised by qmail-smtpd.
As reflected in the modified qmail-smtpd(8) man page, qmail-smtpd must be invoked with three arguments: hostname, checkprogram, and subprogram. If these arguments are missing, qmail-smtpd will still advertise availability of AUTH, but will fail with a permanent error when AUTH is used.
hostname is simply used to form the CRAM-MD5 challenge. qmail-smtpd invokes checkprogram, feeding it the username and password, in the case of LOGIN or PLAIN, or the username, challenge, and response, in the case of CRAM-MD5. If the user is permitted, checkprogram invokes subprogram, which just has to exit with a status of 0 for the user to be authenticated. Otherwise, checkprogram exits with a non-zero
status. subprogram can usually be /usr/bin/true (or /bin/true, depending on your flavor of OS).
If the user is successfully authenticated, the RELAYCLIENT environment variable is effectively set for the SMTP session, and the TCPREMOTEINFO environment variable is set to the authenticated username, overriding any value that tcpserver may have set. The
value of TCPREMOTEINFO is reflected in a Received header.
Enhancements:
- bug: AUTH PLAIN 334 response not RFC compliant. Reported by Mark Crispin
- .
- change: Set TCPREMOTEINFO environment variable to authenticated username. (Previously only set locally to qmail-smtpd.)

m23 is a software distribution system for Debian GNU/Linux that lets you install and administrate hundreds of clients over an existing network easily.

m23 project can partition and format clients and install a Debian GNU/Linux operating system and thousands of software packages.

The administration is done with a Web interface, which can be accessed from any PC connected to the server.
