2020-11-12modernize ctrl function for magma & kuznechik TLS usageIgor Kirillov1-21/+17
modernize magma & kuznechik ctrl functions for EVP_CTRL_TLSTREE mode. add some minor updates to store master key for using in magma TLSTREE mode.
2020-05-18Fix code formating.Nikolay Morozov1-87/+87
All tabs replcaded with spaces. One file was 2 tabs fornating.
2020-05-13Add static to functions that not need to be exportedVitaly Chikunov1-49/+57
After registration rework many callbacks not need to be exported. Also, some functions inconsistently declared static in headers and non-static in the code. Finally, some functions just not need to be exported.

2020-05-12gost_grasshopper_cipher: Remove redundant codeVitaly Chikunov1-237/+3
Not needed after cipher registration converted into table way.
2020-05-12gost_grasshopper_cipher: Rework cipher registrationVitaly Chikunov1-0/+99
This only adds registering via tables, but not removing obsolete code.

2020-02-29cppcheck: Variable is reassigned a value before the old one has been used.Nikolay Morozov1-3/+1
Plus some minor chnages - function defenition doen't match function declaration - Consecutive break statement is unnecessary. - Type missmatch in format string

2018-07-31Optimize out skip_sections and add tests for ACPKM-MasterVitaly Chikunov1-17/+9
ACPKM-Master is from R 23565.1.017-2018, it will be required for ACPKM-OMAC for TLS 1.2.

2018-07-26Set default value for CTR ACPKM limitVitaly Chikunov1-2/+2
Default limit for Kuznyechik is 4KiB, from TLS 1.2 recommendations. As a consequence it does not need to be configured via EVP_CTRL_KEY_MESH. Also, explicitly set ACPKM limit in tests.

2018-07-25Fix grasshopper-ctr reinitializationGleb Fotengauer-Malinovskiy1-8/+9
Also, document why CTR IV size is now set to 16, so user is noted to set IV appropriately to full extent (including counter). Basically, it's for openssh (and alike) to make it copy IV from privilege separated process.
2018-07-23grasshopper: Fix OFB implementation.Vitaly Chikunov1-41/+4
Previous implementation was not OFB at all, and fail tests. Note: This implementation is for fixed width 128-bit IV which makes shift regiser redundant.
