Strong 2 way encryption class for PHP (Uses the mcrypt PHP extension)

pyMoul: Python tools for Myst Online - URU Live (MOUL)

This is a swig-based python wrapper for the OpenPACE library.

Tiny command line tool for speed optimized single file encryption/decryption.

rtl2832_entropyd is a program that is designed to feed entropy into the linux /dev/random kernel entropy pool. It automatically forks and runs as a daemon, unless one of the testing options, -o or -t, are selected. Then it never forks. To use it, you need an rtl2832 USB dongle. They are relatively cheap (< $10 on ebay), and are actually used to listen to a broad range of radio transmissions. This application exploits the radio noise in the atmosphere to extract entropy. The kernel already has a module to use the rtl2832 for its intended purpose, listening to radio, so if you want to use it to generate entropy, you will have to blacklist that module, so it doesn't load. If it is loaded, this program will not be able to acquire the rtl2832 device, and won't run. Create the file /etc/modprobe.d/blacklist-dvb_usb_rtl28xxu.conf with the line blacklist dvb_usb_rtl28xxu in it. The project website is an html version of the man page, so you can find more complete information there.

sIRC is a Secure IRC Communications Program, using MD5 Checksums and RC4 Cipher encryption.

Simple drag & drop file encryption tool. based on python and uses PyCrypto to encrypt the inputted files with AES encryption. Then sqlite database file is generated with a unique key to store the encrypted files and folders in binary blobs for later decryption.

Samizdat is a toolkit for Java for building Kerberos secured distributed, message-oriented applications. The toolkit contains base classes that simplifies the management of Kerberos login contexts as well as flexibly sign and seal messages between principals using the Java GSS API. The toolkit contains Transformation classes for Kerberizing JMS traffic as well as a super-lean HTTP based protocol stack that supports both Synchronous (RPC) and Asynchronous modalities.

Using encryption to secure your code or text. Click File->Run to run your code using Ruby, see the pop up for output. Never save your text or code to disk unencrypted. Don't forget your password. Encryption is error-persistent.

secureDATA is a simple and easy to use encrypted personal information manager. It can store both textual information (passwords, usernames, electronic receipts, etc), and (as of v1.6) files. It uses AES-128 encryption via the Python Cryptography Toolkit.

SJEA version 1.0 - Simple Java Encryption Algorithm. SJEA is a simple command-line binary encryption algorithm (symmetric block cipher) written in JAVA. It uses a password and a byte-vector array to scramble the input file.

Java library with Cryptographic algorithms. Easy to use Crypto algorithms. Works on Windows, Linux, Android. No external lib dependencies, no useless abstractions, no 'crypto provider'. Elliptic curves was borrowed from BouncyCastle and simplified a lot. Most of EC classes are custom algorithms for certain curves. Can be easily deleted if u dont need them. With couple of classes u can parse and construct those ugly ASN.1 structures, look at RSA and EC key formats for example. No bad dependencies between classes, so u can easily cut off unnecessary code and simply include what u need in your project. Feel free and simple without headache. We are using class Binary as best for us to work with byte arrays. Simple classes for console-like colored apps in GUI-mode. Look also http://demo.sls.team

SMScryptor encrypts and decrypts messages sent from any mobile phones using : - AES 256 encryption - J2ME MIDP2.0 CLDC1.1 - ECMAScript - Apache / PHP / mysql

Stegeek is very simple tool, that takes several files,encrypt, and mix them into one file. Also add some redundancy. The result is, that we have one archive and N keys. It should not be possible to guess N, if you have archive and up to N-1 keys.

stegotools is a suite of UNIX command-line applications to read/write hidden information from/in files using steganography. It currently fully supports 24bpp bitmap images.

OSX Application to keep notes and information safe under 448 bit blowfish encryption system. The application is in beta stage, with some major bugs around. You are advised to verify the bug list.

Tcpconns:simple package for rapid development of multi-threaded client/server solutions (JAVA OpenJDK17+) with TLS (V1.3).

After 20/may/2026 this project only includes the rsp32, ds32 and ds64 checksums and developed and optimized in Linux

Updated to recommend the AES 256 CTR Galois mode The past versions was using a method based in the 2001 wikipedia information, and in 2007 the Galois mode was applied then now we recommed on the Galois mode, ok

This is a more secure file encryption program which uses SERPENT cipher and WHIRLPOOL+SHA-256 hash functions in key creation and for integrity checking.

designed to hide messages in jpg and png images without the requirement for any plain-text files. uses aes256 on data, using an sha256 hash of the password as the encryption key. rotates the password by 1 character, and uses an sha256 hash of that for the random seed for the image pointer access. security and invisibility of data is currently being peer-reviewed (since ~2014). At this point it looks like no vulnerabilities have been identified yet. this will evolve further, but remain a console / command application. I will be adding some additional supported file types soon (thinking mp3...). includes (default) option to compresses message with zlib before encryption any ideas / suggestions would speed up the process. This software is intended to be run on a system under the user's control (so keyloggers etc. are not considered).
