Discussed offline; adding a crypto.rs file for each precompile to hold just the pure cryptography implementation.

This would be the code that gets called by the Crypto trait.

Research direction
Examine existing precompile modules in the repository (e.g., precompile directory) to understand current structure. Identify each precompile that requires a crypto implementation. Create a crypto.rs file for each, implementing the Crypto trait functions for that specific precompile. Ensure separation of concerns as discussed in the issue. Consider reviewing any linked issues or comments for further guidance.
