VerifyRequest

A list of grant tokens. For more information, see Grant Tokens in the AWS Key Management Service Developer Guide.

Identifies the asymmetric CMK that will be used to verify the signature. This must be the same CMK that was used to generate the signature. If you specify a different CMK, the signature verification fails. To specify a CMK, use its key ID, Amazon Resource Name (ARN), alias name, or alias ARN. When using an alias name, prefix it with “alias/”. To specify a CMK in a different AWS account, you must use the key ARN or alias ARN. For example: Key ID: 1234abcd-12ab-34cd-56ef-1234567890ab Key ARN: arn:aws:kms:us-east-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab Alias name: alias/ExampleAlias Alias ARN: arn:aws:kms:us-east-2:111122223333:alias/ExampleAlias To get the key ID and key ARN for a CMK, use ListKeys or DescribeKey. To get the alias name and alias ARN, use ListAliases.

Specifies the message that was signed. You can submit a raw message of up to 4096 bytes, or a hash digest of the message. If you submit a digest, use the MessageType parameter with a value of DIGEST. If the message specified here is different from the message that was signed, the signature verification fails. A message and its hash digest are considered to be the same message.

Tells AWS KMS whether the value of the Message parameter is a message or message digest. The default value, RAW, indicates a message. To indicate a message digest, enter DIGEST. Use the DIGEST value only when the value of the Message parameter is a message digest. If you use the DIGEST value with a raw message, the security of the verification operation can be compromised.

The signature that the Sign operation generated.

The signing algorithm that was used to sign the message. If you submit a different algorithm, the signature verification fails.
