    Stegcore

    Stegcore

    A cross-platform crypto-steganography toolkit

    Stegcore combines cryptography and steganography to hide encrypted data inside ordinary files. It encrypts your payload before embedding it, so the hidden content is unreadable even if someone extracts it, and invisible to anyone who doesn't know it's there. Unlike basic steganography tools that hide data without encrypting it, Stegcore ensures the payload is cryptographically protected at rest. Unlike pure encryption tools, the payload isn't even visible. Designed for journalists,...

    Vigen

    Vigen

    UTF-8 Multi-pass Tableau de Vigenère Encryption Rotation Engine

    Vigen is a Unicode UTF-8 multi-pass rotation encryption system based on the classic Tableau de Vigenère. Vigen is an experiment using this particular cypher, intended for those who are interesting in building their own encryption tables. Vigen can generate exceedingly strong rotation cyphers that are probably unbreakable without the given keys and tables. Vigen might even generate military grade cyphers, although I make no claim as to the security of the cypher. Vigen is for encrypting UTF-8...

    Naeon

    The safest way to store private data in untrusted (cloud) environments

    Naeon secures data in untrusted off-site storage through a layered approach: files are compressed, then AES-256 encrypted with a randomly generated 128-character passphrase yielding approximately 762 bits of entropy — far beyond the reach of both classical and quantum brute-force attacks. The ciphertext is obfuscated by prepending and appending random byte blocks, making the result unidentifiable as an encrypted file. The payload is then sharded into one private chunk — holding the...

    cross-platform (Java) file encryption and archiving tool

    Java based API (library) and console utility for cross-platform file and directory encryption and archiving. Encrypts single files up to 9.2 EB length. Directories can be encrypted as sets of single files in a single action. Uses Twofish (CBC) and SHA-256. Security level is strong and benefits from the PWS3 (Password Safe) encrypted file format. The level can be lowered to 128-bit key-length (normally 256).
