Backup P2P is a peer to peer application doing automated and secured backups inside a community (Jabber, XMPP). Each user shares some available space on his disk with others, to be able in return to remotely backup some of his own data.
SLEncrypt is a python module for encryption with 11 ciphers at the moment, including ADFGVX, Autokey, Caesar/ROT13, Vigenere, XOR and a lot more. It contains functions allowing you to easily encrypt/decrypt files. The code is about 95% PEP 8 compilant.
It load the current public-timestamp-block from publictimestamp.org and store it in a file to use it e.g. as a signature in an e-mail software.
The project is inactive and not under development anymore.
Sharemind is a secure multiparty computation system that allows you to process data without seeing it.
IMPORTANT: The version available on this page is a seriously outdated version that is kept available as an educational tool. More recent versions with more features and better quality are available from http://sharemind.cyber.ee/.
Atera all-in-one platform IT management software with AI agents
Ideal for internal IT departments or managed service providers (MSPs)
Atera’s AI agents don’t just assist, they act. From detection to resolution, they handle incidents and requests instantly, taking your IT management from automated to autonomous.
This project aims to provide an opensource Matlab-based development framework to conduct side-channel attacks. Part of this framework are Matlab classes, functions, scripts, and demos.
A smart card-based public key cryptography system based on elliptic curves, using AES for session key generation and SHA for hashing. This project will include the smart card software, terminal software, and a public key server.
Hide your data from any scans for fingerprints at forensic analysis. Fragger is an concept to fragment files into many small files by scrambling the content of the source file.
sanesigner is a high level digital signature api component. it support generating and verifying digital signatures as well as encryption and decryption using public keys, and lots of other features in between.
Security for usb flash drives. Uses basic encryption to make sure your data is safe, on all platforms. This application is written in C++, GUI is still to be considered. PRE-ALPHA STAGE, DO NOT USE ON IMPORTANT DATA!
Pure managed C# implementation of well-known cryptographic hash functions such as SHA-family (SHA0, SHA1, SHA2), MD-family (MD2, MD4, MD5), RIPEMD, Tiger, Haval, Snefru and others.

Originally made to crack /etc/passwd files from *nix utilizing the GPU. Uses GLSL and OpenGL. Acts as a parallel to John the Ripper, but for the GPU. Supports both ATI and nVidia, anywhere OpenGL can run.
This is a simple ANSI-C implementation of Triple-DES (as described in NIST Special Publication 800-67.) This implementation also includes an 8-bit version that can be used in microcontrollers with memory constraints.
This tool encrypts text using polyalphabetic codetables, like the encryption systems in the middle ages. It can be used for simple text encryption with a small password or as a One-Time-Pad with a random codetable for 100% secure text encryption.
Java based Portable hashing application capable of multiple individual file signatures or proprietary group signatures (1 signature for a folder and all its contents). GUI and command line in the same executable. -sha1 -sha256 -sha51 -md5 -crc32
This is a Hash Calculating tool that calculates MD2,MD5,SHA-1,SHA-256,SHA-384,SHA-512 hash of text or a file. This has GUI developed in java swings.All it needs is sun jre installed.
Botan is a C++ crypto library Note: all versions of botan served on sf are OBSOLETE AND NOT SUPPORTED IN ANY WAY. Go to http://botan.randombit.net for the latest stable/supported release.
otp.el is a one-time-password implementation in emacs lisp, suitable for generating one time passwords with the MD5 algorithm. It's designed to be plugged in to tramp.
JChecksum allows you to obtain the hash of a given file using a simple GUI. Hash algorithms supported include MD2, MD5, SHA-1, SHA-256, SHA-384, and SHA-512.
Python wrapper around a small subset of the OpenSSL library. Includes: X509 Certificates, SSL Context objects, SSL Connection objects using Python sockets as transport layer. The Connection object wraps all the socket methods and can therefore be use
Shasummer is a SHA hashsum utility in Java. It can calculate SHA1, SHA256 and SHA512 hashes of a file or of a directory (and its subdirectories) and verify the hashes later. Shasummer has a graphical and a command-line interface.
