Bee2: a cryptographic library

What is Bee2?

Bee2 is a cryptographic library which implements cryptographic algorithm and protocols standardized in Belarus.

Bee2 fully supports the following standards (see apmi.bsu.by/resources/std.html):

1. STB 34.101.31 (belt): data encryption and integrity algorithms.
2. STB 34.101.45 (bign): digital signature and key transport algorithms over elliptic curves.
3. STB 34.101.47 (brng): cryptographic algorithms of pseudorandom number generation + one-time passwords.
4. STB 34.101.60 (bels): secret sharing algorithms.
5. STB 34.101.66 (bake): key establishment protocols over elliptic curves.
6. STB 34.101.77 (bash): sponge-based algorithms.

Bee2 partially supports cryptographic data formats defined in the following standards:

1. STB 34.101.78 (bpki): a PKI profile.

Additionally, Bee2 implements digital signature algorithms standardized in Russia and Ukraine.

Build

mkdir build
cd build
cmake [-DCMAKE_BUILD_TYPE={Release|Debug|Coverage|ASan|ASanDbg|MemSan|MemSanDbg|Check}]\
      [-DBUILD_FAST=ON]\
      [-DBASH_PLATFORM={BASH_32|BASH_64|BASH_AVX2|BASH_AVX512|BASH_NEON}]\
      ..
make
[make test]
[make install]

Build types (Release by default):

• Coverage — test coverage;
• ASan, ASanDbg — address sanitizer;
• MemSan, MemSanDbg — memory sanitizer;
• Check — strict compile rules.

The BUILD_FAST option (OFF by default) switches from safe (constant-time) functions to fast (non-constant-time) ones.

The BASH_PLATFORM option (BASH_64 by default) requests to use a specific implementation of the STB 34.101.77 algorithms optimized for a given hardware platform. The request may be rejected if it conflicts with other options.

What is the logo?

The logo of Bee2 is taken from a self-portrait engraving by Francysk Skaryna, the famous Belarusian medieval printer, enlightener, translator and writer. The engraving is full of riddles, mysteries and cryptograms. One version is that a bee in the right-bottom corner, our logo, designates the constellation known as Apes (Latin for bees) in Skaryna's time. This constellation was later renamed in Musca Borelias (Latin for northern fly) and then absorbed by Aries.
