Java implementation of Shamir's Secret Sharing algorithm as described in Applied Cryptography [as LaGrange Interpolating Polynomial Scheme].

SharedSecret is a program used to negotiate a shared secret (password) by two hosts in secure way over the Internet. The software is written in C, based on client/server architecture with initial intention to run on POSIX-Compliant Operating Systems.

Strong cypher with unique recursive alghorythm of bitwise gamma with good avalanche and diffusion. Recurse allow explore quality and parameters at short sequences of data and keys and extrapolate it on very long data and keys.

SharpPrivacy aims to be a full-featured implementation of the OpenPGP standard. Along with it we want to provide an easy-to-use GUI. SharpPrivacy is currently in beta phase. The first beta version has been released.

SharpPrivacyLibrary is a complete RFC2440 ( OpenPGP specifications ) implementation. It is coded in c# .NET and it is a fully PGP 8.0 compatible API.

<b>SicHer</b> is an encryption client that will allow secure chat across the internet using AES and a Diffe-Hellman key exchange.

Signed dynamic HTTP content. Used for recognizing hacked website content from the surfers view.

Very simple to use symmetric Java encryption utility. Please write a review. Email me with any questions or problems.

A GLib/GTK+ classical encryption analysis and reversal tool that brings together multiple techniques into a single program to aide in decryption.

Generate and retrieve passwords for different websites that you may register. Web based (php) for easy retrieval. Customizable with favorite user id, password length and key! Simple and safe password retriever out there! Please CHECK the Project Website.

SSPE: Simple Security Policy Editor is a simple distributed firewall with an central ascii administration. It uses two plain manually edited ascii-files and some other, static files for each of the target-machines to generate iptables.

This project has moved to https://github.com/julesbl/ssp and is now PHP7 complient and works in composer. The objective of these routines is to supply a secure login system to be wrapped round php applications and websites so that developers do not need to write their own. These libraries have been hardened against most web type attacks. Now has internationalisation and multiple languages.

Simple Stego is a steganography tool written in C++ that hides data in the least significant bits of a PNG image.

A kind of encryption named "simple stream encrypt". The length of plaintext segment or the length of key is not limited, but must greater than zero. The lengths of every plaintext segment in a process don't require equivalency.

Simple XOR Encryption is written in c++ and can encrypt files using insecure XOR encryption. Could be used to form framework for implementing XOR encryption in other programs, such as encrypting save game files in games, etc. Tested on Windows + Linux.

The CRY utility provides the ability to perform AES-256 symmetric key encryption of files. This is a light weight Linux utility and does not depend on PKI infrastructure. Rather, pre-shared encryption keys are used to protect your files.

You can use this program to calculate your file Hash value, also you can use this to verify the file you had downloaded.

A Public Key Cryptographic system based on OpenSSL and MySQL.

Simplebackup is a cross-platform backup program. It reads a configuration file then builds a compress backup set, finally places the compressed files into another location (a directory, a remote http,ftp,sftp server or even one or more email accounts).

Cryptography fascinates everyone. A variety of encryption techniques and ciphers are used to code important data. A polyalphabetic cipher is one of the simplest cipher one can make. This is a Java program to implement polyalphabetic cipher. [How the cipher encodes?] Input Data: helloaf Key: love l - 12th letter in Alphabet o - 15th letter in Alphabet v - 22nd letter in Alphabet e - 5th letter in Alphabet Now: h(l) e(o) l(v) l(e) o(l) a(o) f(v) Further: h(+12) e(+15) l(+22) l(+5) o(+12) a(+15) f(+22) where +(number) meaning shifting the character forward by the respective number of places. So the result comes out to be: tthqapb and the data is encrypted.

Skein 512-512 hash algorithm implemented in Bash. Prepare to have your CPU pegged, and for simple hash calculations to take around 10 seconds. Hit the Home tab for details.

SlimPGP is a pure Java implementation of OpenPGP protocol as defined in RFC2440. Current version implements most of the features in the OpenPGP.

The Small Crypto Library is a collection of C++ classes for public and private key cryptography. The Small Secure Socket Library uses SCL for maintaining secure IP connections.

Application based on asymmetric cryptography (ECC) allows encrypt and decrypt files and generates digital signatures. Currently implemented algorithms include ECDSA and ECIES.
