- Refactoring and code modification in module **gostcipher** to increase the performance of encryption algorithm 'kuznechik' (uses precomputation values of the 'gf' function; the performance of the encryption function has increased by an average of 5..10 times)
- Refactoring and code modification in module **gosthash** to increase the performance of hasing (uses precomputation values of the 'l, s and p-transformation', function; the performance of the encryption function has increased by an average of 2..7 times)
- Added the **gostoid** module that implements generating cryptographic object IDs for the **gostcipher**, **gosthash**, **gosthmac** and **gostsignature** modules
