This tool can create one-time-password values based on HOTP (RFC 4226: HOTP: An HMAC-Based One-Time Password Algorithm), TOTP (RFC 6238: TOTP: Time-Based One-Time Password Algorithm) and OCRA (RFC 6287: OCRA: OATH Challenge-Response Algorithm) standards, and also supports client side of OAuth protocols (1.0a, 2.0).

SATURN is now a fully-functional stream cipher. It is in active development. The underlying algorithm is SATURNrng, a cryptographically-secure random number generator. SATURNrng is seeded with a 480-bit key and a 480-bit nonce which then produces a random stream used to encrypt a plaintext.

OhCrypt lets you easily encrypt and decrypt files using some of the most popular algorithms, like AES, Blowfish and Serpent. With OhCrypt, you can secure your data with a password-based encryption algorithm through a clean and simple interface. It demonstrates state of the art of cryptology techniques, such as password hashing and salt. Ohcrypt also features self-extractable and self-destructive encrypted files

Optimized implementation of RC4 (Rivest Cipher 4, ARCFOUR) in ASM (x64) for Linux and Windows.

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

ClearPass (formerly BlowPass) is web based password storage system that uses the Blowfish algorithm and a Host-Proof design pattern.

sectar: a program that creates encrypted tape archives(tar files), using the AES algorithm Rijndael. Encryption exported under exemption TSU 740.13. Was star, now sectar.

Why FinalCrypt? 1. Most people choose Disk-Encryption as it's easier to unlock a whole drive, but Big-Brother or Malware can then also read all your files. Only use File-Encryption! 2. Most software uses recently broken AES encryption. 3. Soon The Shor's algorithm will instantly break all assymmetric encryption with Quantum Computers. 4. FinalCrypt uses Symmetric One Time Pad Encryption, which is the most unbreakable encryption there is. 5. FinalCrypt is the only "One Time Pad", OpenSource, Cross-Platform, (Bulk) File Encryption Software available.

RC4.NET is a library that adds support for encrypting/decrypting using the symmetric RC4 algorithm in the .NET environment. The library is written in C# language, and performs equally well on both the Microsoft CLR and Mono platform.

GDLOG is an implementation of the General Number Field Sieve algorithm for discrete logarithm problem in GF(p).

HashSum is a .NET port from GNU's md5sum and sha1sum. It supports: hash algorithm selection between MD5 and SHA1 (more could be added later) and compatibility between HashSum and GNU's checksum file format

Rcrypto is the encryption and decryption software for windows XP,vista and 7 to keep your data secure from unauthorized users. It uses the highly secure algorithm to encrypt every byte of the file.

Digest is a command-line utility which can be used to calculate and verify checksums of any files, similar to md5sum or RHash, but using modern hash algorithms. Supported algorithms: BLAKE, BLAKE2, Grøstl, JH, Kupyna, MD5, SHA-1, SHA-2, SHA-3, Skein, SM3, Streebog, Whirlpool. Usage: digest [-c] <algorithm> <filename(s)> For example, if you want to calculate the checksums using skein512/256 algorithm, use this command: digest skein512/256 * > checksums.skein To verify the checksums: digest -c skein512/256 checksums.skein You can get a full list of supported algorithms and test the performance of different algorithms on your PC using the command: digest test <iterations> <filename> This will calculate hash sum of <filename> multiple times (number of times is specified by <iterations>) and output the results with precise timings. Note: if you have a 64-bit operating system, use 64-bit binary of the utility, because it is significantly faster for large files.

The algorithm allows any kind of weights (costs, frequencies), including non-numerical ones. The {0, 1, ..., n-1} alphabet is used to encode message. Built tree is n-ary one.The algorithm is based on a set of template classes : Cell(SYMBOL, WEIGHT), Node(

This is an experimental program that encrypt/decrypt/divide/join files. This program uses a new algorithm made by me, this algorithm is experimental and I working on it, every day this algoritm will be better.

Cryptomni is a program which can encrypt and decrypt files using the one-time pad cipher. If a key is truly random, kept secret, and never reused, this encryption algorithm can be proven to be unbreakable.

A simple working implementation of 64-bit DES encryption/decryption alogrithm in C++. Could act as guide to undestanding the algorithm. Its buggy so help me out :-)

DecodeBase64 does exactly what the title says: it decodes strings encoded with the Base64 algorithm. Source code is provided in both Java and C++.

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

PureBasic Shamir Secret Sharing is an open-source, self-contained and educational implementation of the Shamir Secret Sharing Scheme, written entirely in PureBasic. Shamir Secret Sharing is a cryptographic method that splits a secret into multiple parts (shares), such that any combination of at least T shares can reconstruct the original secret, while any number of shares fewer than T reveals no usable information. This implementation operates over the finite field GF(257), allowing correct handling of all byte values (0–255) without loss, making it compatible with any type of string or binary-compatible data. Main Features Complete implementation of Shamir Secret Sharing Arithmetic over GF(257) Compatible with all character strings Robust Lagrange interpolation Safe modular inverse computation Shares encoded in hexadecimal (3 characters per byte) Clear, well-commented source code ⚠️ Disclaimer This project is intended for educational and demonstration

This software provides an easy graphical way to encrypt your text documents from source code , text files ,scripts even jpeg files .It is a enhanced version of my earlier project https://sourceforge.net/p/xorencrypt which used win32 GUI . This is a demonstration of working of XOR encryption which was used by Germans in World War II (http://en.wikipedia.org/wiki/Lorenz_cipher) . Besides from XOR'ing the message with password after every encryption the key changes pseudorandomly. The password you provide is hashed ( SHA256 ) and saved into the encrypted file to check if the password provided is correct.This algorithm has limitations in general more the numbers of relative characters in the password to plaintext more secure will be the encryption. XOR encrypt has a 3.5 of 5 editors rating from softpedia http://www.softpedia.com/get/Security/Encrypting/XOR-Encrypt.shtml

An application to encrypt files using Tiny Encryption Algorithm(TEA) with user defined keys of 4 to 16 character length

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.

This xxteac program utilizes the "Corrected Block TEA" encryption/decryption algorithm by Roger Needham and David Wheeler. The original algorithm has been slightly modified to allow arbitary length passwords / password files.
