Free encryption program software for linux

Eureka Public Key was created due to numerous requests for a public key application using our strong encryption techniques. The basic principle for its use is one creates their own public key and distributes the key to whomever they will be transferring encrypted files with.

When one receives a key, they import it into their key database. You can create and import as many keys as you wish. Both public keys are used in the cryption process. You select your particular public key to use and the public key of the person who will receive it.

When a file has been received you put in your public key that matches the one they used and select their public key that was used in the encryption. See the Encryption, Decryption and Import/Export sections for more information on these topics. To create a public key, click on Keys then Create Public Key or click on the gold key icon under the menu items.

All you have to do is define a name for the public key and click on Create. All encrypted files will be written to the Encryptions folder. Likewise, all decrypted files will go to the Decryptions folder. If a file already exists with the same name, it will be overwritten.

Encryption:

To Encrypt a file, click on File then Encrypt.

All you have to do is select Your public key, their public key and click on Encrypt or press enter then select the file you want to process.

The file selected will be encrypted and then placed in your Encryptions folder. Now you can send this file in the manner you prefer.

Note that this application encrypts in a binary format. In other words, it uses the full 256 character set and is not a text file. You will need to send it as an attachment if you are using email to transmit it.

Decryption:

To Decrypt a file, click on File then Decrypt.

All you have to do is select Your public key, their public key then click on Decrypt and select the file you want to process.

The file selected will be decrypted and then placed in your Decryptions folder.

EasyCrypt is a small Python program that encrypts or dercypts files using AES encryption standard.

The program is still in early development. It can be used to easily encrypt your files on the go with pretty good security. It works or all systems that support Python. (Windows, Unix, MacOS, ...).

The program uses PyCrypto (link here) library to encrypt/decrypt the file. (Pyhton doesnt have yet an official implementation of the AES algorythm). Since the sourceforge doesnt have any downloadable package, I included in the cvs tree the version of the library used in the program.

Usage (example):

> pycrypt --encrypt TestFile.jpg TestFile.jpg_enc mypassword
(An encrypted file has been created)
> pycrypt --decrypt TestFile.jpg_enc DecryptedFile.jpg mypassword
(The original file is recovered)

FireFTP project is a free, secure, cross-platform FTP client for Mozilla Firefox.

FireFTP is a free, secure, cross-platform FTP client for Mozilla Firefox which provides easy and intuitive access to FTP servers.

Along with transferring your files quickly and efficiently, FireFTP also includes more advanced features such as: directory comparison, syncing directories while navigating, SSL encryption, file hashing, and much more!

Eureka Encryption Global Edition contains file encryption, multiple encryption, merge encryption, multiple file encryption, embedded applications (Crypt Words, Steganographer, Interface) and other tools such as a file shredder and scrambler.

Eureka Encryption Global Edition is available for Windows, Mac and Linux. Other applications are available from the website.

This is a fast and simple, yet hard to crack encryption program. It uses XOR encryption with variable key, based on the password that user inputs to the program, it rumbles bits in the bytes, etc.

The newer versions have an extra 7bit coding, so that it is usable inside the XML (it is to be used inside the QtBaza in the next release), and that doubles the size of the file. The program is written using ANSI C and should run on all OSs that have a C compiler (UNIXes, Windows, MacOS, VMS, ...).

Gaim-Encryption uses NSS to provide transparent RSA encryption as a Gaim plugin.
Main features:
- Automatically creates a public/private key pair for you upon loading the plugin
- Automatically transmits your public key to other users.
- Supports 512 - 4096 bit keys.
- Saves keys of known users, and warns you if their public key has changed.
- Embeds all encryption and keys inside HTML, so if the other user doesnt have the plugin, they will get a little message telling them about the plugin, and wont get a screen full of garbage.
- Stores keys in human readable files in your .gaim directory, in case you ever need to copy/edit them by hand. Which you really shouldnt have to do.
- Automatically recognizes if you are chatting with someone who has the plugin- see the Preferences dialog.
- Available for the Windows version of Gaim.
- Modular and extensible. If you want to define a different type of encryption, you can use this plugin as a wrapper to take care of transporting the encrypted binary over the IM pipe.

qrypto is a project aimed to provide simple, easy to use Blowfish encryption across popular languages for enhanced data security.
