SigningAlgorithm => Str

The signing algorithm that was used to verify the signature.

Valid values are: "RSASSA_PSS_SHA_256", "RSASSA_PSS_SHA_384", "RSASSA_PSS_SHA_512", "RSASSA_PKCS1_V1_5_SHA_256", "RSASSA_PKCS1_V1_5_SHA_384", "RSASSA_PKCS1_V1_5_SHA_512", "ECDSA_SHA_256", "ECDSA_SHA_384", "ECDSA_SHA_512" =head2 _request_id => Str
