MyPGP provides a graphical user interface for pgp encryption and signing. It is fully compatible with OpenPGP, and GnuPG. It relies on BouncyCastle libraries for the cryptographic primitives. It uses file system folders to store keys, either single or key rings, organized as a nested tree of folders. It can also create lists of keys for bulk operations.

AVGVSTO - Advanced Security Suite with USB Binding AVGVSTO is a Python-based encryption tool that binds sensitive data to a physical USB drive , ensuring decryption is only possible when the authorized device is connected. It combines AES-256 encryption with robust USB hardware authentication and brute-force protection for enhanced security. 🔍 Key Features Hardware-Bound Encryption Files can only be decrypted when the original USB drive (used during encryption) is connected. The USB's unique identifier (st_dev) is embedded in the encrypted file. AES-256 with PBKDF2 Secure key derivation using SHA-256 with 1 million iterations for password-to-key conversion. Brute-Force Protection After 3 failed decryption attempts , encrypted files/folders are automatically deleted. Recursive Folder Encryption Encrypt entire directories and nested files with a single operation. Modern GUI Intuitive interface with drag-and-drop support, real-time feedback, and responsive design.

This script is capable of cracking multiple hashes from a CSV-file like e.g. dumps from sqlmap. Over 17.000 md5-hashes in a CSV-file get cracked with a 14.300.000 lines wordlist in less then 1 min. Lines wich cant get cracked with the wordlist get stored in a .leftToCrack-File to further process with another Wordlist or the bruteforce-tool. In addition to the wordlist-cracker I created also a bruteforce-tool named CSVHashBrutforcer.

This is an implementation of elliptic curve cryptography using the Montgomery and Edwards curves Curve25519, Ed25519, Ed448-Goldilocks and Curve448, using the Decaf / Ristretto encoding.

stores a free text field strongly encrypted on a cell-phone or PDA using AES encryption with 256 bit -- can be used for storing passwords, pins and other sensitive data

The PKI Framework (PKIF) is a cross-platform library for performing PKIX-compliant certificate processing. It includes support for SCVP, OCSP, CMS and Timestamps. It uses Windows CAPI, NSS or Crypto++ for cryptographic services and hardware support.

Libecc is an Elliptic Curve Cryptography C++ library for fixed size keys in order to achieve a maximum speed. The goal of this project is to become the first free Open Source library providing the means to generate safe elliptic curves.

A steganography tool. You can hide 2Gb file in multiple images, supported almost all graphic formats. Average capacity ~ 40%. Useful for publishing censored materials in the Internet. Details on the project's website (stegoshare.sf.net).

A slightly reduced strength bulk encryption. In exchange for the reduced strength, you get the ability to rsync the encrypted files, so that local changes in the plaintext file will result in (relatively) local changes to the cyphertext file.

The Martus (TM) Bulletin System is used by human rights and social justice groups to track violations. This Java program is as easy to use as email. Bulletins can be encrypted or searched, and can be backed up to a remote server. See www.martus.org.

This project is a C++ library which allows incorporating DKIM into an existing MTA or other application. It provides full support for signing, verifying, and SSP. It is compliant with RFC 4871.

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.

JHide is simple steganography tool aimed to demonstrate basic steganography techniques.

ShredBitz is a free and simple file shredder tool that can wipe selected files from any hard disk drive. ShredBitz is written in the java programming language and uses a custom written algorithm for shredding. ShredBitz is a very powerful tool.

MetFS is a filesystem in userspace that is FUSE based, encrypted, dynamic sized (increase when new data added, decrease when data removed), single file when it's unmounted and very fast. MetFS 's proved to be running on Linux and FreeBSD.

SD4L is a suite of Linux tools including a graphical user interface which allow the creation of, and access to ScramDisk as well as TrueCrypt encrypted container files. In particular, SD4L provides a Linux driver which enables mounting of containers.
