pqproto

pqproto is a practical framework for experimenting with post-quantum cryptography (PQC) in real-world security protocols.
It provides command-line–based client–server prototypes for both classical and PQ-secure communication. The core libraries and tools used are:

• OpenSSL with PQC support (v3.5.0 & above)
• liboqs and oqs-provider for hybrid/PQ key exchange and signatures
• strongSwan for IPsec integration
• Circl and other PQC libraries for algorithm diversity

Protocols Covered

• TLS / mTLS
• DTLS
• QUIC
• IPsec
• OAuth
• SSH
  (More coming soon)

Prerequisites

• OpenSSL 3.5.2 with post-quantum support
• GCC with C11 support
• pkg-config (sudo apt install pkg-config) for dynamic library path configuration
