tls-parser
Small library to parse TLS records.
Decision gist · record as of 2026-08-14
Yes, if you need to parse TLS records in Python. The package is stable, has no dependencies, and is proven in production use. However, verify the license terms in the repository first, and check whether it supports the TLS versions your use case requires. The aging maintenance status means security updates may be slow; monitor the repository for any critical fixes.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.8 or later.
- Low install friction with no runtime dependencies.

What it is and what it does
tls_parser is a lightweight library for parsing TLS records from raw binary data. It extracts and interprets the structure of TLS protocol messages, making it useful for security tools, protocol analysis, and SSL/TLS inspection workflows. The package has no runtime dependencies, keeping it minimal and easy to integrate.
The library is used by SSLyze, a popular SSL/TLS scanning tool, indicating it is battle-tested for real-world TLS analysis. It supports current Python versions and has been maintained since 2017, though recent development activity has slowed—the last release was 2025-04-06 and the repository shows a last commit of 2025-10-19.
Use it for
- Analyze TLS handshakes and protocol messages in security testing frameworks
- Build SSL/TLS inspection tools that need to parse raw protocol data
- Debug TLS communication issues by examining record structure and content
- Integrate TLS parsing into network monitoring or intrusion detection systems
- Validate TLS record format compliance in protocol implementations
