⁠eCapture(旁观者): capture SSL/TLS text content without a CA certificate using eBPF.

---

⁠Introduction

• SSL/TLS plaintext capture, support openssl\libressl\boringssl\gnutls\nspr(nss) libraries.
• GoTLS plaintext support go tls library, which refers to encrypted communication in https/tls programs written in the golang language.
• bash audit, capture bash command for Host Security Audit.
• MySQL query SQL audit, support mysqld 5.6\5.7\8.0, and MariaDB.

⁠Getting started

This Docker image provides an easy way to use ecapture⁠, a powerful tool for capturing SSL/TLS plaintext data directly from Linux or Android systems without requiring a CA certificate. With ecapture, you can collect decrypted HTTPS traffic in real time for security analysis, debugging, or auditing.

Key Features & Use Cases:

• Capture SSL/TLS plaintext: Intercept and analyze encrypted web traffic from applications without modifying system configurations or installing CA certificates.
• Suitable for Security Monitoring: Essential for penetration testing, incident investigation, or network auditing in production, testing, or development environments.
• Broad Environment Support: Works on Linux and Android devices with amd64 (x86_64) or arm64 architectures.
• Easy Deployment: The prebuilt Docker image allows for quick setup across various systems without the need to compile or install dependencies manually.

How to Use:

1. Pull the Image

   docker pull gojue/ecapture:latest
   

   Copy

2. Run ecapture via Docker
   Grant necessary privileges (ecapture requires privileged mode and access to host network for full functionality):

   docker run --rm -it \
     --privileged \
     --net=host \
     -v /lib/modules:/lib/modules:ro \
     -v /usr/src:/usr/src:ro \
     gojue/ecapture \
     [ecapture options]
   

   Copy

   Replace [ecapture options] with ecapture’s command-line arguments, such as tls for HTTPS or see the README for more.

3. Example:
   To monitor SSL/TLS traffic for a given process or port, refer to usage examples in the eCapture Trobleshooting⁠.

Requirements & Notices:

• The container must run with --privileged and --net=host options.
• The host system requires Linux (kernel 4.18+ recommended) and support for eBPF.
• Not recommended for shared or production environments without understanding security implications.
