v0.3.2

Fixed

• Fixed SHA-1 main loop issue

v0.3.1

Fixed

• Fixed all Clippy lint issues across the codebase

v0.3.0

Added

• New sign subcommand: ruscrypt sign --rsa for creating RSA digital signatures
• New verify subcommand: ruscrypt verify --rsa for verifying RSA digital signatures
• RSA signing and verification functions with support for both "n:d/n:e" and PEM key formats
