...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

...PBKDF2-HMAC-SHA256 (200k iterations, adjustable) for password hardening. Key separation via BLAKE2s - independent keys for encryption and MAC. BLAKE2s-MAC authentication - 16-byte tag, any modification = instant rejection. Streaming keystream generator - secure, large-scale XOR without key reuse. Fake padding (HEAD/TAIL) - obfuscates binary boundaries and payload structure. Precise size encoding - restores original payload exactly. Supports files up to 128 MB per encrypted block. No dependencies, fully offline, cross-platform Python implementation. ...

Simple, lightweight, cross-platform (Windows / Linux / ARM6 Linux), cross-arch (x32 / x64), standalone command line file encryption program. GnuPG is probably the best application for cross-platform encryption. However, its usage on Windows PCs may be inconvenient (installation administrator rights; large executable size for perhaps just a one-time file decryption, complicated command-line switches for stronger encryption). NCrypt would fulfill this task, but does not operate on 64-bit...

A encryption library for C++ "DEL-X" that uses a 3d encryption algorithm. It can work with any key size from 8bit- 4096bit with a 512 byte block size.

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.

The Moonbounce API is a set of high level objects that encapsulate pieces of the Bouncycastle lightweight crypto API. Moonbounce significantly simplifies RSA key generation, signing, encryption/decryption and verification of both byte arrays and files.
