SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires bcrypt, passlib, and includes scripts (resource) components.

What problem does it solve?

This Skill addresses passlib bcrypt incompatibility issues, enabling password hashing and verification to work correctly with newer bcrypt packages.

Core Features & Use Cases

  • Compatibility Fix: Solves (trapped) error reading bcrypt version and password verification failures due to bcrypt.__about__ removal.
  • Version Pinning: Offers options to pin bcrypt to a compatible version or upgrade passlib.
  • Direct Usage: Provides a method to replace passlib with direct bcrypt usage for long-term solutions.
  • Use Case: When a Python project using passlib's bcrypt handler encounters errors after bcrypt package updates.

Quick Start

Apply the fix by choosing one of the following options: Pin bcrypt to version 4.0.1, upgrade passlib to version 1.7.5 or higher, or replace passlib with direct bcrypt usage.

Frequently Asked Questions about fix-passlib-bcrypt-incompatibility

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
Why does passlib password verification fail after updating the bcrypt package?

Passlib password verification fails after bcrypt updates because newer bcrypt versions removed the bcrypt.__about__ module, causing silent errors and hash verification failures.

How do I fix the trapped error reading bcrypt version in passlib?

To fix the trapped error reading bcrypt version, pin bcrypt to version 4.0.1, upgrade passlib to version 1.7.5 or higher, or replace passlib with direct bcrypt usage.

What is the best way to resolve passlib bcrypt incompatibility in Python?

The best way to resolve passlib bcrypt incompatibility is to pin bcrypt to version 4.0.1 for a quick fix, upgrade passlib to 1.7.5 or higher, or switch to direct bcrypt usage for a long-term solution.

Can I use direct bcrypt instead of passlib for password hashing?

Yes, you can use direct bcrypt instead of passlib for password hashing. This approach replaces passlib's bcrypt handler entirely, providing a long-term solution that avoids future compatibility issues.

Do I need Python and both passlib and bcrypt installed to apply this fix?

Yes, you need Python with either the bcrypt or passlib libraries installed to apply this compatibility fix. The solution targets scenarios where password hashing or verification fails after bcrypt package updates.

When should I pin bcrypt versus upgrade passlib to fix password hashing errors?

Pin bcrypt to version 4.0.1 for an immediate compatibility fix, upgrade passlib to 1.7.5 or higher to maintain the existing handler, or replace passlib with direct bcrypt usage for a long-term solution.
