Libraries and tools written in .NET managed code (MS/mono) to interact with GRC's Perfect Paper Password system [https://www.grc.com/ppp.htm] Source moved to GitHub: http://github.com/ErebusBat/pppNET
This is a library for easy accessing chip cards /smart cards via a chipcard reader. It currently works under Linux, FreeBSD and Windows. It is tested with Towitoko and Kobil readers.
OpenRCA is a highly flexible and modular Certificate management and Registration Authority based on J2EE technology. OpenRCA is designed to be a very flexible, extensible and low cost enterprise PKI solution.
OSN is an open source open protocol distributed social network. Public key cryptography makes the network resilient to spam. User profiles are based on FOAF XML and users can migrate their profile from one site of the federation to another.
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.
iCrypt is an easy to use gui program written in 100% pure python. It implements the Crypto and ezPyCrypto modules to provide secure RSA public key encryption.
Use prime numbers and pseudorandom number generators to create pseudorandom permutations to "shuffle" bits of given data (passwords, logins, PINs, files, directories). It is designed to be very secure (I hope so).
Rainmaker is a command line pseudo random number generator designed to work on multiple platforms. Rainmaker can be used produce cryptographically strong non-blocking output in many formats (Base-16, Alphanumeric, Numeric , and Alpha only modes).

OW.NET -- 1-Wire API port from Java (and J#) to C#. Use the Dallas 1-Wire and iButton chips with standard C# using a serial adapter (also CF.net) or the TMEX drivers on the Windows platform. No J# distribution installation required.
PyGFS is a reliable and secure distributed file system that runs completely in userspace. It supports x509 certificate authentication, authorization and encryption mechanisms to provide secure access over insecure networks.
....* and higher versions) in order to crypt (or decrypt) a file using a password. The library accepts the following parameters: an input file, the operation to perform, and the user password.
XMLStore is a new project that cares about XML-based Databases Access with users Authentication and Authorization and more such as dead-lock accesses.
It will be soon introduced to other kind of databases such as SQL,...
Generate RSA key pairs of arbitrary length; convert text between formats or use keys to transform/crypt text. Supports decimal, hexadecimal, base64 and text input and output. Entirely ANSI C++; no external dependencies.
A package of Rijndael, Twofish and Serpent encryption algorithms implemented in x86 assembly. Meant to learn basics of assembly, learn about the algorithms or to be used in a C program.
KeyStone is an editor program for Java keystore files, licensed under the GPL. KeyStone may help make your life easier if you're working with symmetric cryptography in Java.
This project can be used to manage plugins in JAVA applications the framework provides checking of electronic signatures as well as hooks for user interaction (for example when certs are found that are not issued from a trusted authority
A tool to hide a file into a image with no affects the size. It uses a steganography techinique that change the least significant bit in the RGB color systems of non compressed images to store the bits of the file to hide.
BruteNet is a system of the distributed brute force and distributed calculations built on user extensions capable to solve a great number of problems related to the partition on a lot of machines.With sample extention you can distribute brute md5-hash
This project provides a simple Java-based steganography tool that can hide a message inside a 24-bit colour image so that knowing how it was embedded, or performing statistical analysis, does not make it any easier to find the concealed information.
This software is a set of tools that hides C source code in txt files. Also the software is able to restore the txt files to C source code again. This work is based on the tool c2txt2c by Leevi Martilla. Csteg needs a book file in txt format to hide C so
Pseudo Random Number Generator (PRNG) frontend using libtomcrypt. It simply writes pseudorandom data (using sober-128, fortuna, yarrow or rc4 algorithm) on standard output. The output may be encoded to base64, base85 or hex or just left binary.
