excerpt: >-
After a year since it stemmed off NetPGP, the OpenPGP library
shares little code in common with its ancestor.
Enjoy new features, better performance, and better
compatibility with other implementations.

:cpp: C++

Meet RNP, an RFC4880-compliant OpenPGP library written in {cpp}.

RNP was born at Hong Kong-based Ribose and is maintained under its initiative.
Originally stemmed from NetPGP, it has little in common with its ancestor now
after a year of development—after a clean-up of legacy code,
corrected compatibility issues with GnuPG and other implementations,
improved performance and added cutting-edge features.

Feel free to use RNP in your software!

This line feels a little out of place. I'm thinking it could be reworded to include mention of the BSD licensing though maybe?



== Getting started with RNP

If you’re deploying OpenPGP in a Ruby-based application,
there are bindings
(see RubyDoc footnote:[https://www.rubydoc.info/github/riboseinc/ruby-rnp/]).

Since it’s written in C++, you can call RNP from Objective-C code,
or with ctypes under Python.

RNP’s binaries `rnp` and `rnpkeys` can be installed via Homebrew or YUM,
with Debian packages coming next.
You can use the binaries similarly to GnuPG’s command-line tools
(see supported flags and use cases in RNP’s README footnote:[https://github.com/riboseinc/rnp/blob/master/README.md#usage]).

== Why RNP?

* It’s a proper library, in contrast to GnuPG/GPGME footnote:[See https://news.ycombinator.com/item?id=5180217[GnuPG is not a library (2013)]]. Ruby bindings are available with Python & Go bindings in the works, and you can use it wherever you can call C++ code.
* It’s implemented in C++ and offers constant memory footprint with large amounts of data.
* It offers comprehensive cipher support, including (uniquely) the SM algorithm family—a desirable feature if you deploy cryptography in mainland Chinese market.
* Its development is active (with the help of Ribose) and focused on adding cutting-edge features.

== Which algorithms does RNP support?

The following ciphers, encryption modes and hash functions are supported:

* Symmetric: IDEA, Triple DES, CAST5, Blowfish, AES-128, AES-192, AES-256, Twofish, Camellia-128, Camellia-192, Camellia-256, SM4
* Symmetric encryption modes: CFB, AEAD-EAX, AEAD-OCB
* Hash: MD5, SHA1, RIPEMD160, SHA-256, SHA-384, SHA-512, SHA-224, SM3
* Asymmetric: RSA, ElGamal, DSA, so-called DSA2 (i.e. DSA with keys larger then 1024 bits), ECDSA/ECDH (with some subset of curves which later on will be expanded), EdDSA, SM2.
