Encryption/Decryption demonstration app using the S-DES algorithm. Use the Java runtime environment 11 for execution. The GUI pops up that allows entering a 10-bit encryption/decryption key in binary (0, 1 digits) and the plaintext/ciphertext in the same form (8-bit). Executing the algorithm, decription of the encoding/decoding functionality is provided in the three main text boxes.

v1pad is a command-line tool that encrypts and decrypts files using one-time-pad encryption. v1pad uses a virtual pad, meaning that the one-time pad is generated dynamically based on user input instead of being stored in a file. The name v1pad is an abbreviation for Virtual One-Time Pad.

Simple program to encrypt text. Programa simple para encriptar texto.

JCryptor uses the Caesar-cipher to encrypt keystrokes on-the-fly. It can also be used to decrypt an encrypted text easily. Caesar-cipher is a simple encryption algorithm, developed by Julius Caesar, to encrypt his correspondence with Cicero in the ancient world. Therefore it uses a simple character substitution method to replace a given character by another. A keyshift of thirteen is called ROT13. ROT13 can be decrypted by encrypting it again with ROT13. Even today this simple method is used...

It is a simple password manager for your PC and Smartphone. It works like a text editor and uses a strong cryptography algorithm to generate the end file.

P.I.G.: Privacy In Gedit, a plugin for gedit, encode and decode text to base64.

This is free Java desktop application to keep your note in safe from others using the Encrypting Decrypting symmetric key algorithm, it's easy to transfer your note form source to another in confidential manner.

A small encryption / decryption application that we are giving away free of charge. Version 1.0.00 - RSA only at the moment. But later versions will have a plug-in system for adding more algorithms.

A Visual Basic implementation of Bruce Schneier's Solitaire Encryption Algorithm that encrypts plain text by means of a deck of ordinary playing cards.

Vijner 974 E-Sys (2048 bits and unlimited encryption). Enables easy (un-)encryption from text input or .txt file, and to (un-)encrypt raw files, with Vigenère Algorithm + unlimited encryption keys. Simple and powerful. Adapt to fit your needs.

This program is a replica of SafeSex by Nullsoft. Written from scratch on the .NET Framework 3.5. It allows you to keep useful notes in a safe manner, as it allows for encryption using the world renowned AES encryption algorithm.

jCryptPad stores text informationen hierarchical, e.g. passwords, important texts etc. The data is saved in a encrypted xml file. Encryption is done with the AES algorithm. Additionally a password generator and a text encryption editor is also included.

Szyfrator is a GUI application for Windows XP/Vista/7. It encrypts and decrypts text messages using the public RSA algorithm. It generates two 256 bit keys: public and private and was designed to be very easy to use.

TextCodec can encode texts using simple algorithm and then decode them by using statistical language data.

SysK allows to crypt text by using system informations calculate the algorithm. For each user,the crypt algo will be different. It's written in C language for Linux x86. The objective is to allows it to crypt streams, binaries and more.

KCrypto is a KDE2 file encryptor. It uses the Rijndael ( block cipher algorithm AES winner ) public domain c++ class implementation written by Szymon Stefanek , and it is capable of encrypting and decrypting every kind of file ( text and binary ) i
