Decision gist · record as of 2026-08-14
Yes, if you are building for StarkNet and need native cryptographic operations in Python. The package is actively maintained, has no known vulnerabilities, and offers broad platform support via precompiled wheels. However, verify the license terms before use, and be aware that the small community footprint (3 stars) means limited third-party documentation or troubleshooting resources.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.10 or later; on Windows, pywin32 is an additional runtime dependency.
- Medium install friction due to compiled wheels across many architectures; requires Python 3.10 or later.
- Actively maintained with recent release (2026-04-03) and no known vulnerabilities.

What it is and what it does
crypto-cpp-py wraps the crypto-cpp C++ library to expose cryptographic hashing and message signing operations for StarkNet applications in Python. It depends on ecdsa and sympy for elliptic-curve mathematics, plus pywin32 on Windows. The package is distributed as precompiled wheels for Python 3.10+ across a wide range of architectures (x86_64, ARM, PowerPC, s390x, RISC-V) and operating systems, minimizing build friction for most users.
The library is actively maintained and has received recent updates (version 2.0.0 released 2026-04-03) that dropped support for older Python versions and legacy 32-bit architectures. It carries no known security vulnerabilities. However, the unclear license status and minimal community engagement (3 repository stars) mean you should verify licensing terms and community support before adopting it in production.
Use it for
- Signing and hashing StarkNet transactions or messages within a Python application.
- Building StarkNet wallet or smart-contract interaction libraries that require cryptographic operations.
- Integrating ECDSA-based message authentication into StarkNet-compatible dApps.
- Performing elliptic-curve cryptography operations where sympy and ecdsa alone are insufficient.
