This tool leverages eBPF technology to capture SSL/TLS plaintext without a CA certificate on Linux and Android. Supporting libraries like OpenSSL and GoTLS, it aids in security audits by enhancing visibility in encrypted communications and facilitating network traffic analysis. Root access is required and Windows or macOS systems are unsupported, making it ideal for security professionals and administrators focused on auditing encrypted exchanges efficiently.

Cilium is an open source project providing robust eBPF-based network, observability, and security features. It enables native routing, overlay networking, and efficient load balancing through a flat Layer 3 network. The tool further enhances bandwidth management and secures L3-L7 protocols with an identity-based security model, suitable for service-to-service communications. Leveraging Prometheus metrics and the Hubble observability platform, Cilium offers comprehensive monitoring capabilities. Built on the latest Linux kernel technologies, it's ideal for scalable and agile distributed applications.

bpftrace uses eBPF to compile scripts into bytecode through LLVM, enabling comprehensive tracing on Linux. Inspired by awk and C, it supports dynamic tracing and various probe types for system performance analysis. It includes editor plugins and detailed resources such as manuals and tutorials, beneficial for developers interested in advanced tracing capabilities.

BCC is a toolkit for developing kernel tracing and manipulation programs using eBPF, facilitating performance analysis and network traffic control. It supports Linux kernel 4.1+, offering tools and examples for tasks like tracing disk I/O and counting kernel function calls, with language support for Python and Lua. BCC ensures safe execution without kernel interference, allowing for customization to meet specific requirements.
