Want to create your own CA? Have a pain typing openssl command? With Certificate Utilities, we include many functions like create private key. This is the most professional and free certificate toolkit based on openssl and lisenced under under GPL!

CheckMate is a program designed to generate all kinds of checksums and/or hashes. Checksums can simply be displayed or saved and used to verify the integrity of a file later on.

A simple file checksum utility for Microsoft Windows.

Para proteger la información sensible de miradas ajenas, no basta con ocultarla en una carpeta anónima o ponerla en un archivo comprimido; lo suyo es cifrar los datos para que nadie pueda leerlos

Encriptador es un sencillo sistema para convertir un texto cualquiera en caracteres equivalentes sin sentido, y después poderlos volver a convertir en texto normal. En una única interfaz realizaremos tanto la encriptación como la desencriptación. Sólo hará falta pegar el texto en su ventana correspondiente, que depende si es para desencriptar o para encriptar, y listo

Hasher is a .NET class library to help programmers implement standard hashing and checksum algorithms into their own software. Written entirely in C#, Hasher providers a uniform interface to easily use any of the algorithms contained within this library

A library written in Visual C# for encrypting a text message into an image file, and decrypting an image file to get the text message using Rijndael Algorithm, RSA Algorithm, and LSB Substitution Algorithm.

CryptAPI is a C# library that contains unimplemented algorithms in the .NET framework (NT, NTLM, BlowFish, DES and MD5) linking and emulating the crypt() unix function re-programmed in C#. The main purpose is to provide backward compatiblity.

CryptPad is a .NET Compact Framework 1.1 simple notes application which operates encrypted text documents (.wrc) based on user provided password. This way one can store confidential data on Windows Mobile operating systems.

Crypto is a simple, easy to use Windows application for encrypting text files using RSA encryption. Crypto has an elegant user interface and a powerful encryption backend.

The purpose of this project is to create a library of cryptographic functions for .NET, in fully managed C#. This will extend the existing .NET framework crypto functionality.

A program for encrypt/decrypt files or text inside clipboard with a password or a certificate located either in certificate storage (certmgr.msc) or in a .cer file. You just have to drag and drop files and folder to the application.

Crypto.Net is a free and open cryptography library for C# and .Net. AES (Rijndeal), Twofish, Blowfish, RSA, Diffie-Hellman, SSL/TLS, X509-Certificate builder, stream cipher modes or a secure netowrk stream are only some features of this library.

This library exposes security functionality to the programmer, such as random number generation, hashing, salted hashing, message authentication code, symmetric encryption, asymmetric encryption, hybrid encryption, digital signature and in-memory protection. The library is accompanied by a sophisticated reference implementation, that demonstrates how to make use of the CryptoLibrary.

Debaser is a powerful password generator which has plans to be turned into a password manager.

Dotnet library for PC/SC-based access to Mifare Desfire smartcards. It is based on copyrighted opensource SpringCard SDK. Please check project wiki for license limitations

OpenPGP Keyserver written in ASP.NET (C#) This keyserver is not designed to synchronise with other servers. Suitable for deployment within a windows based organisation where sharing keys with internet keyservers is not required/desirable.

Formerly known as DotNetOpenId, this library brings easy and flexible OpenID, OAuth and InfoCard to the .NET platform. Official web site is at http://www.dotnetopenauth.net/, which includes source code downloads.

DrCrypt, based on basic xor(exclusive or) encryption which is designed to be fast and reliable. Also DrCrypt supports 3 platform.(Java, .NET, Win32)

Dr. HydeFile hide files in a big crowd of files. Filesize: 1 KB - 20KB Number of Files: 500 - 20.000 Files Can you find a file in this crowd?

Simple console application generating passwords in quite easy and simple way. Application allows user to copy generated passwords to clipboard.

A simple app that enables you to sign the files and verify their integrity/authenticity using the ECDSA and SHA-512. I originally developed this app for my university course, but I also decided to post it on GitHub on Sourceforge. This application is made for educational purposes only. Despite having well-functioning cryptographic features, it may not be reliable. This application is provided with no warranty or guarantees of any kind. Use it at your own risk! Made with the help of the ChatGPT and Perplexity. GitHub page: https://github.com/Northstrix/ECDSA-File-Signer

A library written in Java and C# for crypt,encrypt and generate key pairs using the ElGamal algorithm.

Simple Base64 encoding/decoding in C#

Programa que encripta y desencripta mensajes y los puede pasar a archivo de texto
