module Aws::Sigv2
This is a legacy signer. You should AWS signature version 4 instead, as provided by the `aws-sigv4` gem.
This exists primarily to support SimpleDB which does not accept version 4 signatures.
## Known Limitations
-
This signer is only compatible with AWS services that use the Query protocol. Only around 18 of the 80+ AWS services use this protocol.
-
**This signer is not capable of producing a valid signature for Amazon S3.** It is not aware of S3 sub-resources and how to properly insert them into the URI path. Amazon S3 supports signature version 4 in every region, and so `aws-sigv4` should be used instead.
-
This signer does not provide a method to compute pre-signed URLs. This is available in the `aws-sigv4` gem.
