Gegeo developed security and networking features across the projectdiscovery/dsl and projectdiscovery/mapcidr repositories using Go, cryptography, and network programming. For projectdiscovery/dsl, Gegeo built an RSA encryption helper that enables DSL-driven encryption with PEM-formatted public keys, PKCS#1 v1.5 padding, and base64 output, streamlining secure data handling for downstream services. In projectdiscovery/mapcidr, Gegeo enhanced IP address manipulation by adding support for multi-octet dash-based IP range expansion and fixing IP filtering correctness, including IPv4-in-IPv6 handling. Comprehensive unit tests accompanied both features, demonstrating a focus on reliability and maintainability. The work reflects depth in CLI tool development and protocol handling.
