Algorithm guide

How to use

Dynamic

• copy gost_34_12_magma_dynamic.h
• copy magma_dynamic.dll
• copy magma_dynamic.lib

Static

• copy gost_34_12_magma_static.h
• copy magma_static.lib

Use in your code

uint64_t encrypt(uint8_t* byPKey, uint64_t data_block);

uint64_t decrypt(uint8_t* byPKey, uint64_t data_block); 

Testing speed (10Mb)

• C++/C encryption time: 275 milliseconds
• ASM encryption time: 253 milliseconds
• ~ same time
