 ### Prerequisites
 
 - GCC compiler
-- OpenSSL development libraries (`libssl-dev` on Ubuntu/Debian)
 - Git (for version tracking)
 - Make

 ## Security Features
 
 - Uses `/dev/urandom` for cryptographically secure random number generation
-- Optional keyboard entropy mixing using HKDF (Hash-based Key Derivation Function)
-- SHA-256 pad integrity verification
+- Optional keyboard entropy mixing using simple XOR operations
+- Custom 256-bit XOR checksum for pad identification (encrypted with pad data)
 - Read-only pad files to prevent accidental modification
 - State tracking to prevent pad reuse
+- **Zero external crypto dependencies** - completely self-contained implementation
