Educational Implementation - Not Professional Cryptographic Software

PythonStark is NOT cryptographically audited and is NOT secure for production use.

DO NOT USE THIS SOFTWARE FOR:

• Production systems
• Security-critical applications
• Financial services or cryptocurrency
• Authentication or access control
• Privacy-sensitive applications
• Any application where security failures could cause harm

PythonStark is an EXPERIMENTAL EDUCATIONAL PROJECT designed for:

✅ Learning about zero-knowledge proof systems
✅ Academic research and cryptographic experimentation
✅ Teaching ZK-STARK concepts and implementations
✅ Personal projects and prototyping

❌ NOT for production deployment
❌ NOT for security-critical systems
❌ NOT for commercial applications

• No security audit performed
• Not constant-time - vulnerable to timing attacks
• No side-channel protection - power analysis, EM attacks
• Educational implementations - custom crypto primitives
• Limited testing - no adversarial testing
• Memory safety - secrets may remain in memory

• Learning about zero-knowledge proof systems
• Academic research and experimentation
• Teaching cryptography concepts
• Personal projects and prototyping

• Production systems of any kind
• Security-critical applications
• Financial or cryptocurrency systems
• Authentication or access control
• Handling sensitive or personal data
