KeyId => Str

The Amazon Resource Name (key ARN (https://docs.aws.amazon.com/kms/latest/developerguide/concepts.html#key-id-key-ARN)) of the asymmetric CMK that was used to sign the message.

Signature => Str

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 (https://tools.ietf.org/html/rfc8017).
• 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 (https://tools.ietf.org/html/rfc3279#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 AWS CLI, the value is Base64-encoded. Otherwise, it is not Base64-encoded.

SigningAlgorithm => Str

The signing algorithm that was used to sign the message.

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
