Detect & Fix Cryptographic Failures in Python Web Apps

Detect & Fix Cryptographic Failures in Python Web Apps

This AI agent skill is designed to detect, audit, and remediate cryptographic failures in Python web applications developed using FastAPI and Flask frameworks. It specifically focuses on issues identified by the OWASP A04:2025 ranking, addressing the absence, misuse, or weakness of cryptography protecting data at rest and in transit.

What this skill does

• Detects weak or missing password hashing algorithms in Python code.
• Identifies predictable randomness caused by incorrect imports.
• Scans for hardcoded keys that may lead to credential leakage.
• Reviews TLS/SSL configurations to ensure proper certificate verification.
• Analyzes JWT configurations for key strength and algorithm pinning.
• Ensures symmetric encryption modes are up-to-date and properly authenticated.

Who it is for

This skill is ideal for developers and teams using AI coding agents like Claude Code, Cursor, and Codex who are concerned with enhancing the security of their Python web applications. It is particularly useful for security-conscious developers and DevSecOps teams auditing cryptographic code.

Use cases

• Scanning Python web applications for cryptographic issues during development.
• Performing regular security audits on existing FastAPI and Flask applications.
• Remediating identified cryptographic vulnerabilities in legacy codebases.
• Educational purposes for understanding common cryptographic pitfalls in Python.

Technical details

This skill leverages AI agent capabilities to interact with codebases, focusing on the analysis and remediations associated with modules like hashlib, random, ssl, jwt, passlib, and cryptography. It supports inquiries about cryptographic security, password hashing, JWT configuration, and more, enabling comprehensive security assessments and improvements in Python applications.
