Release History

1.2.5 (05.09.2021)

  • Fixed a several minor bugs

1.2.4 (17.09.2020)

  • Fixed a default initial vector bug (added default initial vector for 'magma' algorithm)

1.2.3 (23.05.2020)

  • Added Python version checking (use version 3.6 or higher)

1.2.2 (15.05.2020)

  • Fixed a MAC calculation bug when using padding in the gostcipher module (in earlier versions (including 1.2.1), the MAC with padding was calculated incorrectly (the bug was in the 'msb' and 'update' functions))

1.2.1 (13.05.2020)

  • Fixed a MAC calculation bug when using padding in the gostcipher module

1.2.0 (07.05.2020)

  • 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

1.1.2 (02.05.2020)

  • Refactoring gostcipher module (changed the class hierarchy to remove code duplication)
  • Refactoring gosthash module (remove code duplication)
  • Fixed some minor bugs
  • Updated docstring in accordance with the Google Python Style Guide

1.1.1 (20.04.2020)

  • Use **kvargs in the new function with default parameters (gostrandom, gosthash, gosthmac, gostpbkdf)
  • Add the ability to pass data to the new function from gosthmac
  • Fixed some minor bugs in the gostrandom module

1.1.0 (15.04.2020)

  • Refactoring code gostcipher module (changed the class structure)
  • Each module has its own exception class added
  • In the new function of the gostcipher module for MAC mode, it is now possible to pass data for MAC calculation, followed by calling the digest method without first calling the update method
  • In the new function of the gosthash module, it is now possible to pass data for hash calculation, followed by calling the digest method without first calling the update method
  • Added new exceptions for various conflict situations
  • Fixed some minor bugs

1.0.0 (08.04.2020)

  • First release of 'gostcrypto'
