Free email encryption program software for linux

Come And Go Encryption provides an encryption program based off one-time pads.
Cum And Go Encryption is a very basic program to encrypt or decrypt a program using a variant of the one-time pad. This allows for almost uncrackable encryption.
Why is it still crackable? The program uses one relatively small key to XOR the contents of another file, encrypting it.
A one-time pad uses a very large key (about the same size as the file/data to encrypt) and is completely random. Still, the encryption is good enough to mask the identity of a program or document, or stop someone from accessing that document or program.
The origins of this program were an effort to stop a specific kind of movie and image from being viewed normally.
Installing is a breeze: simply run the program. Put it anywhere you like, it wont matter as long as you put the full path to the program to encrypt/decrypt.
Run the program to see a basic description of its use.
This program works very well in windows but was designed for use in Linux/UNIX. The stdout option allows for decryption to standard output, allowing one to pipe the programs decrypted data to another program.
This could be used to view an encrypted movie without having to write the whole movie to disk; the only problem with this is that on some Operating Systems pipes are slow and inefficient, especially with a high-bitrate movie. Steps will be taken to speed this up in the future.
Enhancements:
- Fix password use so the password is not shown in "encrypted" files
- Use an actual encryption method, and not a cheesy XOR
- Adapt CAG to use modules such as SHA, Crypt, MD5, and others

Eureka Encryption SDK Shared Library allows you to use Eureka Encryption in your own applications. Encrypt or decrypt strings or files.

Eureka Encryption shared Library installation instructions:

Start a terminal session and navigate to the folder where the files are located and enter the following commands:

chmod +x eursdk.so (this may be optional)

cp eursdk.so /usr/lib

ldconfig /usr/lib

The library is now ready for use. Load up the sdkhelp.htm file with any web browser for detailed information on its use.

Should anyone wish to translate the help files in other languages and send them to me, I would be happy to include them and repackage the tarball.

Eureka Messenger 4 software delivers secure and private messaging and unlimited file transfers over the internet.

This application no longer requires the VB Runtimes, but this new version 4 is not compatible with the previous windows version.

Installation:

Actually there is no install for this application. You can run it right where you unzipped it, or copy the files unzipped wherever you want them.

If there is a firewall on either machine, some configuration may be required in order to make a connection.

The program has a Help file to guide you on how it works, although it is simple enough to run without much assistance.

You probably need to issue a chmod +x messenger before it can run. On some linux systems you may also need to issue a chmod +755 messenger.

Email Administration Utility provides an IMAP-based email account management utility.
The Email Administration Utilities package can be used to manage email accounts with a series of PHP-based scripts through a browser.
Addition, Removal, and modification of accounts is possible as long as an IMAP port is available on the mail server.
The Mailadmin project was originally designed to help owners of domains that were hosted by Hub.Org Networking Services. The company wanted users to be able to create, remove or modify email accounts when ever they wanted, giving them a quicker turnaround for Mail Administration Purposes.
As the utility was developed, tested and matured into what it is today, many users requested more features or contributed reports of issues to help improve the utilities stability. Hub.Org has given me permission to release the utility as an Open Source package so that others may also benifit from the simplicity that the Mailadmin utility offers to those who need complete control over email accounts.
With this in mind, I intend to continue development by adding new features as they are requested and fix any issues that may pop up. The more users who use and test the features that the Mailadmin utility offers will help to improve the functionality offered by Mailadmin. I have opened a Sourceforge account to help manage the development and releases of the utility as it matures into what users and developers see the Mailadmin to be.
Main features:
- Administrator:
- Adding/Deleting Email accounts.
- Setting Account Quotas.
- Obtaining Administrative Access Over Older Accounts.
- Changing An Accounts Password.
- Interfaces with the Cyrus IMAP/POP3 server.
- Transaction Log system, allowing you to track changes or to help debug issues.
- Standard User:
- Changing The Accounts Password.
- In Development:
- Transaction Log system, allowing you to track changes or to help debug issues.

Email::FolderType::MH is a Perl class to help Email::FolderType recognise MH mail directories.

SUBROUTINES

folder_type < path >

Automatically detects what type of mail folder the path refers to and
returns the name of that type.

It primarily bases the type on the suffix of the path given.

Suffix | Type
--------+---------
/ | Maildir
/. | MH
// | Ezmlm

In case of no known suffix it checks for a known file structure. If that
doesnt work out it defaults to "Mbox" although, if the "Mbox" matcher
has been overridden or the default changed (see DEFAULT MATCHER below)
then it will return undef.

matchers
Returns a list of all the matchers available to the system.

DEFAULT MATCHER

Currently the default matcher is "Mbox" and therefore it is always
checked last and always returns 1.

If you really want to change this then you should override
"Email::FolderType::Mbox::match" and/or change the variable
$Email::FolderType::DEFAULT to be something other than Mbox.

use Email::FolderType;
use Email::FolderType::Mbox;

$Email::FolderType::DEFAULT = NewDefault;

package Email::FolderType::Mbox;
sub match { return (defined $_[0] && -f $_[0]) }

package Email::FolderType::NewDefault;
sub match { return (defined $_[0] && $_[0] =~ m!some crazy pattern!) }
1;

Email::Store is a framework for database-backed email storage.

SYNOPSIS

use Email::Store dbi:mysql:mailstore;
Email::Store->setup; # Do this once

Email::Store::Mail->store( $rfc822 );
Email::Store::Mail->retrieve( $msgid );

...

Email::Store is the ideal basis for any application which needs to deal with databases of email: archiving, searching, or even storing mail for implementing IMAP or POP3 servers.

Email::Store itself is a very lightweight framework, meaning it does not provide very much functionality itself; in effect, it is merely a Class::DBI interface to a database schema which is designed for storing email. Incidentally, if you dont know much about Class::DBI, youre going to need to in order to get much out of this.

Despite its minimalist nature, Email::Store is incredibly powerful. Its power comes from its extensibility, through plugin modules and hooks which allow you to add new database tables and concepts to the system, and so access the mail store from a "different direction". In a sense, Email::Store is a blank canvas, onto which you can pick and choose (or even write!) the plugins which you want for your application.

For instance, the core Email::Store::Entity plugin module addresses the idea of "people" in the email universe, allowing you to search for mails to or from particular people; (despite their changing names or email addresses) Email::Store::Thread interfaces Email::Store to Mail::Thread allowing you to navigate mails by their position in a mail thread; the planned non-core Email::Store::Plucene module plugs into the indexing process and stores information about emails in a Plucene search index for quick retrieval later, and so on.
