Bee2evp: an OpenSSL engine

Github Actions Build Status Coverage Analysis

What is Bee2evp?

Bee2evp is a cryptographic library which encapsulates Bee2 into OpenSSL. Bee2evp provides cryptographic services using the EVP interface. Bee2evp is organized as an OpenSSL engine.

Build

[git submodule update --init]
mkdir build
cd build
cmake [-DCMAKE_BUILD_TYPE={Release|Debug|Coverage|ASan|ASanDbg|MemSan|MemSanDbg|Check}] ..
make
[make install]

Build types (Release by default):

Preparations

Before building Bee2evp, it is necessary to build and configure Bee2 and OpenSSL. Bee2evp requires OpenSSL version 1.1.1 or higher.

Building Bee2

See instructions in github.com/agievich/bee2.

Building OpenSSL

  1. Download the latest source files from openssl.org/source.
  2. Unpack files into some directory, for example, openssl-1.1.1.
  3. Go to this directory.
  4. Run the following commands: 
    mkdir build
cd build
../config 
make
make install

By default, OpenSSL {headers|binaries|libraries} will be installed in the directory /usr/local/{include|bin|lib}.

Configuring OpenSSL

  1. Rename /usr/local/ssl/openssl.cnf.dist -> /usr/local/lib/openssl.cnf.
  2. Open /usr/local/lib/openssl.cnf.
  3. Add the following lines (before the [new_oids] section): 
    openssl_conf = openssl_init
[openssl_init]
engines = engine_section
[engine_section]
bee2evp = bee2evp_section
[bee2evp_section]
engine_id = bee2evp
dynamic_path = /usr/local/lib/libbee2evp.so
default_algorithms = ALL
  4. Make sure LD_LIBRARY_PATH includes /usr/local/lib.

BTLS

In this folder, patches for different versions of OpenSSL are provided. These patches support the following ciphersuites defined in STB 34.101.65 (Btls, see apmi.bsu.by/resources/std.html):

  • DHE-BIGN-WITH-BELT-CTR-MAC-HBELT;
  • DHE-BIGN-WITH-BELT-DWP-HBELT;
  • DHT-BIGN-WITH-BELT-CTR-MAC-HBELT;
  • DHT-BIGN-WITH-BELT-DWP-HBELT;
  • DHE-PSK-BIGN-WITH-BELT-CTR-MAC-HBELT;
  • DHE-PSK-BIGN-WITH-BELT-DWP-HBELT;
  • DHT-PSK-BIGN-WITH-BELT-CTR-MAC-HBELT;
  • DHT-PSK-BIGN-WITH-BELT-DWP-HBELT.

An example of applying a patch can be found in travis.yml.
