Utility to encrypt files and streams. Features: encryption with AES, Serpent, Twofish and many other block ciphers supported by Botan; PBKDF2 key derivation; HMAC verification; does not require files, works with pipe input and output
A very simple file encryption tool. Release 1 is a text editor that saves encrypted files. Release 1.1 will include the ability to convert any file, even binary, to a GEF (Gulosh Encrypted File). Release 2.0 brings the strong encryption into play.
Stores and retrieves files in an encrypted archive. Also manages files stored on CDs and DVDs. Other functions are incomplete. PLEASE NOTE: you need to download both an Objectify release and a Public Objects release.
If you need to protect your confidential files in office or shared desktops, here is the robust commandline and GUI utility to do password based encryption using AES. It can encrypt and decrypt a folder structure containing any number of files.
A simple demonstrative commandline tool which can do both file encryption and decryption . It is based on OpenSSL and can support AES / DES / 3DES / BLOWFISH / RC4 cipher algorithms with ECB / CBC / CFB / OFB chaining modes (ECB only for RC4).
Advanced Perl script for DES password cracking. Might be handy for password QA. Brut-force, load Unix passwd/shadow, multi hash crack, input/output file, save/resume cracking state.
AppSignal's MCP server hands Claude, Cursor, or Zed your real errors, traces, and the deploy that shipped them. AI writes the fix; you review the diff.
Sharemind is a secure multiparty computation system that allows you to process data without seeing it.
IMPORTANT: The version available on this page is a seriously outdated version that is kept available as an educational tool. More recent versions with more features and better quality are available from http://sharemind.cyber.ee/.
Hide your data from any scans for fingerprints at forensic analysis. Fragger is an concept to fragment files into many small files by scrambling the content of the source file.
Originally made to crack /etc/passwd files from *nix utilizing the GPU. Uses GLSL and OpenGL. Acts as a parallel to John the Ripper, but for the GPU. Supports both ATI and nVidia, anywhere OpenGL can run.
SSLScan queries SSL services, such as HTTPS, in order to determine the ciphers that are supported. SSLScan is designed to be easy, lean and fast. The output includes prefered ciphers of the SSL service, the certificate and is in Text and XML formats.
Interrogate is a proof-of-concept tool for identification of cryptographic keys in binary material. First and foremost for memory dump analysis and forensics usage. Able to identify AES, Serpent, Twofish and RSA keys as of version 0.0.3.
Java based Portable hashing application capable of multiple individual file signatures or proprietary group signatures (1 signature for a folder and all its contents). GUI and commandline in the same executable. -sha1 -sha256 -sha51 -md5 -crc32
Security for usb flash drives. Uses basic encryption to make sure your data is safe, on all platforms. This application is written in C++, GUI is still to be considered. PRE-ALPHA STAGE, DO NOT USE ON IMPORTANT DATA!
Raiden block cipher: An extremely lightweight and fast block cipher, developed using genetic programming, with the intention to be an alternative to TEA. This cipher is as fast as TEA, and without many of its known weaknesses.
This tool will allow obfuscation of UNIX scripts listing an interpreter as the first line. It is most useful for distributing functionality in a commercial product or a high user volume environment where you wish to hide proprietary information.
fm (file masker) is an easy-to-use commandline cryptographic tool that's small, portable across operating systems, quite secure for most purposes, and licensed to you along with its source code under the gpl.
