|AWS Signature Version 4 for AWS Security Token Service||
We have released a new version of the protocol for authenticating inbound API requests to AWS Services. The new protocol, Signature Version 4, will enable AWS to support future growth and evolution of the AWS business. It introduces a specialized signing key, derived from the long-term AWS Access Key, which is used for the cryptographic signature. It also features incremental modifications in the canonicalization algorithm that streamline signature verification.
This release of the AWS SDK for iOS uses Signature Version 4 for the AWS Security Token Service.
For more information about AWS Signature Version 4, go to Signature Version 4 Signing Process in the AWS General Reference.

#ifdef DEBUG [AmazonLogger verboseLogging]; #else [AmazonLogger turnLoggingOff]; #endif
