My idea is the following.
1. Generate Private Key Hexadecimal Format (64 characters [0-9A-F]).
2. With the generation of the number to be converted into the following:
-Uncompressed private key (WIF)
-Compressed private key (WIF)
-Legacy P2PKH Public address Uncompressed
-Legacy P2PKH Compressed public address
3. Check the addresses
4. The speed of generation, conversion and verification should depend on the machine on which the tool works.
That is, it can read CPU cores and video cards.
To be able to choose where to get computing power - from the processor or video cards or both.
