The Amazon Resource Name (key ARN) of the asymmetric KMS key that was used to sign the message.
The cryptographic signature that was generated for the message.
When used with the supported RSA signing algorithms, the encoding of this value is defined by PKCS #1 in RFC 8017.
When used with the ECDSA_SHA_256, ECDSA_SHA_384, or
ECDSA_SHA_512 signing algorithms, this value is a DER-encoded object as
defined by ANS X9.62–2005 and RFC 3279 Section 2.2.3.
This is the most commonly used signature format and is appropriate for most uses.
When you use the HTTP API or the Amazon Web Services CLI, the value is Base64-encoded. Otherwise, it is not Base64-encoded.
The signing algorithm that was used to sign the message.
