Summary

Logging Redactor is a Python library designed to redact sensitive data in logs based on regex patterns and / or dictionary keys. Prior to 0.0.7, personally identifiable information returned by custom object __str__ or __repr__ methods is not redacted when such non-primitive objects are logged, causing sensitive values to appear in logs that are expected to mask them. This issue is fixed in version 0.0.7.
