BouncyCastle.Cryptography 2.6.1

The Bouncy Castle Cryptography Library For .NET

NuGet NuGet

The Bouncy Castle Cryptography library is a .NET 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 https://www.bouncycastle.org.

In addition to providing basic cryptography algorithms, the package also provides support for CMS, OpenPGP, (D)TLS, TSP, X.509 certificate generation and more. The package also includes implementations of the following NIST Post-Quantum Cryptography Standardization algorithms: ML-DSA, ML-KEM, SLH-DSA, Falcon, Classic McEliece, FrodoKEM, NTRU, NTRU Prime, Picnic, Saber, and BIKE. These should all be considered EXPERIMENTAL and subject to change or removal.

The Legion also gratefully acknowledges the contributions made to this package by others (see here for the current list). If you would like to contribute to our efforts please feel free to get in touch with us or visit our donations page, sponsor some specific work, or purchase a support contract.

Installing BouncyCastle

You should install BouncyCastle with NuGet:

Install-Package BouncyCastle.Cryptography

Or via the .NET Core command line interface:

dotnet add package BouncyCastle.Cryptography

Either commands, from Package Manager Console or .NET Core CLI, will download and install BouncyCastle.Cryptography.

MimeKit
MimeKit is an Open Source library for creating and parsing MIME, S/MIME and PGP messages on desktop and mobile platforms. It also supports parsing of Unix mbox files. Unlike any other .NET MIME parser, MimeKit's parser does not need to parse string input nor does it use a TextReader. Instead, it parses raw byte streams, thus allowing it to better support undeclared 8bit text in headers as well as message bodies. It also means that MimeKit's parser is significantly faster than other .NET MIME parsers. MimeKit's parser also uses a real tokenizer when parsing the headers rather than regex or string.Split() like most other .NET MIME parsers. This means that MimeKit is much more RFC-compliant than any other .NET MIME parser out there, including the commercial implementations. In addition to having a far superior parser implementation, MimeKit's object tree is not a derivative of System.Net.Mail objects and thus does not suffer from System.Net.Mail's limitations. API documentation can be found on the web at http://www.mimekit.net/docs For those that need SMTP, POP3 or IMAP support, check out https://github.com/jstedfast/MailKit
