BouncyCastle

The Bouncy Castle Crypto package is a C# implementation of cryptographic algorithms and protocols, it was developed by the Legion of the Bouncy Castle, a registered Australian Charity, with a little help! The Legion, and the latest goings on with this package, can be found at [http://www.bouncycastle.org](http://www.bouncycastle.org). In addition to providing basic cryptography algorithms, the package also provides support for CMS, TSP, X.509 certificate generation and a variety of other standards such as OpenPGP.

BCrypt.Net-Next

A fixed, enhanced and namespace compatible version of BCrypt.Net port of jBCrypt implemented in C#. It uses a variant of the Blowfish encryption algorithm’s keying schedule, and introduces a work factor, which allows you to determine how expensive the hash function will be, allowing the algorithm to be "future-proof".

BouncyCastle.Crypto.dll

Here at the Bouncy Castle, we believe in encryption. That's something that's near and dear to our hearts. We believe so strongly in encryption, that we've gone to the effort to provide some for everybody, and we've now been doing it for over 15 years! The Bouncy Castle Crypto APIs are looked after by an Australian Charity, the Legion of the Bouncy Castle Inc., which looks after the care and feeding of the Bouncy Castle APIs. If you would like to help support this effort please see our donations page or purchase a support contract through Crypto Workshop. Requests to sponsor specific work on the APIs are also most welcome.

PCLCrypto

PCL Crypto provides a consistent, portable set of crypto APIs for .NET 4.5, Windows Phone 8.0 SL & 8.1 Xaml, Windows Store, Xamarin.iOS, Xamarin.Android. This makes it easier to create cross-platform .NET libraries and apps. Crypto functionality includes asymmetric and symmetric encryption and signatures, and key derivation. PCLCrypto calls into each native platform's crypto API for maximum performance. For RSA operations this produces a 2-100X improvement in performance on Android and iOS over using the standard RSACryptoServiceProvider API.

Virgil.Crypto

Virgil is a stack of security libraries (ECIES with Crypto Agility wrapped in Virgil Cryptogram) and all the necessary infrastructure to enable seamless, end-to-end encryption for any application, platform or device. See below for currently available languages and platforms. Get in touch with us to get preview access to our key infrastructure. https://developer.virgilsecurity.com/ Virgil Security, Inc., guides software developers into the forthcoming security world in which everything will be encrypted (and passwords will be eliminated). In this world, the days of developers having to raise millions of dollars to build a secure chat, secure email, secure file-sharing, or a secure anything have come to an end. Now developers can instead focus on building features that give them a competitive market advantage while end-users can enjoy the privacy and security they increasingly demand.
