…sawg-tacacs-tls13-07) This implementation adds comprehensive TACACS+ over TLS 1.3 support including: ## Core Protocol Changes - Modified crypter to handle TLS vs non-TLS connections properly - TLS connections skip traditional TACACS+ PSK obfuscation - Added UnencryptedFlag validation for TLS connections - Enhanced error handling for TLS protocol violations ## Server & Client Features - Added TLS listener support with configurable certificates - Command-line options for TLS certificate configuration - Support for mutual TLS authentication with client certificates - Backward compatibility with existing non-TLS deployments ## New Files Added - tls.go: Core TLS configuration and listener management - tls_client_option.go: TLS client configuration options - docs/tls_support.md: Comprehensive TLS setup and debugging guide - server_tls_bench_test.go: TLS performance benchmarks - server_tls_optimized_bench_test.go: TLS benchmarks with specialized cert config, tradeoff security for perf ## Command Line Interface ### Server Options: - -tls: Enable TLS support - -tls-cert: Server certificate file path - -tls-key: Server private key file path - -tls-ca: CA certificate for client validation - -tls-require-client-cert: Require mutual TLS ### Client Options: - -tls: Enable TLS support - -tls-cert: Client certificate for mutual TLS - -tls-key: Client private key for mutual TLS - -tls-ca: CA certificate for server validation - -tls-server-name: Server name for certificate validation - -tls-insecure-skip-verify: Skip certificate validation (testing only) ## Security & Performance - Requires TLS 1.3 as per IETF specification - Added Benchmarks test coverage including surge testing This implementation follows IETF draft-ietf-opsawg-tacacs-tls13-07 specification for secure TACACS+ authentication over TLS transport.
