Cryptography detection tool
C++ console application that features unique (at least I think so) symmetric key based file encryption algorithm.
My implementation of AES 256-bit encryption!
Aplikasi PHP Enkripsi-Dekripsi File Menggunakan Algoritma Advanced Encryption Standard (AES-128)
Enyo is a lightweight multistage partition-based encryption algorithm. Enyo cipher demonstrates good resistance to a brute-force attack. It is well suited for small-scale applications where the computational power is a bottleneck.
A C# transparent file encryption example which was implemented with the Transparent Encryption File System Filter Driver SDK. The Transparent Encryption File System Filter Driver SDK allows you to develop transparent on-access, per-file encryption Windows application without the driver encryption knowledge, help you to handle most of the complexity in encryption operations.
Simplest implementation of RSA algorithm encryption and decryption. (In only 13 lines)
BELT (STB 34.101.31) Encryption Algorithm and Hash Function Implementations
LZString port in Haxe
Herradura is a Key exchange scheme in the style of Diffie-Hellman Key Exchange, based on bitwise operations.
Variable size symmetric key encryption algorithm. PHP & JavaScript implementation, small, portable and fast.
This quite implementation for RC4, Encryption Algorithm
Implements the Data Encryption Standard (DES) and Triple-DES (3DES) in Python. Uses a GUI and lets the user input the plaintext in 64-bit hexadecimal format and outputs the ciphertext in 64 bit hexadecimal.
JS Browser Encryption Tool / SCP-1024 Very complex, highly computational encryption algorithm
A simple ruby client for the Caterpillar API
OneTimePad Algorithm implemented in C#
This is a UI based simple custom made encryption and decryption program written in python
AES encryption and decryption algorithms implemented in Verilog programming language
Explaining Affine Crypto System on Sage
Very secure symmetric encryption algorithm with unlimited key length.
Simple data encryption and decryption using AES Algorithm in Java swing. Users will put their hidden key that's the encrypt key alone with his/her message. Remote users only access the message by using the first user key
A customizable encryption scheme for transmitting confidential information via a non-secure channel. It uses Steganography techniques to encode the secret data into an image or video file and can be used multiple times to make it a layered encryption and decrease the risk of being discovered.
