How to Resolve the "The request signature we calculated does not match the signature you provided" Error in Amazon S3

When encountering this error, it's crucial to verify the integrity of your AWS credentials, particularly the access key and secret. Beyond that, specific aspects of your configuration can also contribute to the issue.

Firstly, ensure your config.php file is configured correctly. Based on the provided code, it seems the credentials are being set in the 'default_settings' section. Double-check the 'key' and 'secret' values to ensure they match your valid AWS credentials.

Additionally, the error message suggests that the request signature might also be corrupted. One potential cause of this corruption arises when the object key you're attempting to upload violates certain naming conventions. For instance, object keys cannot start with a period (.). Verify that the 'Key' parameter in your putObject() call does not begin with a period.

By ensuring accurate credentials, proper configuration, and avoiding problematic naming conventions, you should be able to resolve this error and successfully connect to your Amazon S3 bucket.
