Life in the digital trenches





Early release, but complete. This module is not actively maintained. If you wish to use it, please let me know and I’ll get it updated This is a complete implementation of the Signature Version 4 Signing Process. It passes all complete tests provided by Amazon.

URI::Encode version 0.08 made some changes in its default behavior. This change caused some of the tests to fail for this module. Release version 0.006 explicitly sets the desired behavior of URI::Encode. Please upgrade to version 0.006 as it works with all versions of URI::Encode.


This module signs requests destined for a service that requires version 4. Currently, it has only been tested on Amazon’s Glacier service. It should work on any service. If you have issues with other services, please let me know by opening an issue.
