Verifies the specified signature.
public virtual System.Threading.Tasks.Task<Azure.Security.KeyVault.Keys.Cryptography.VerifyResult> VerifyAsync (Azure.Security.KeyVault.Keys.Cryptography.SignatureAlgorithm algorithm, byte[] digest, byte[] signature, System.Threading.CancellationToken cancellationToken = default);abstract member VerifyAsync : Azure.Security.KeyVault.Keys.Cryptography.SignatureAlgorithm * byte[] * byte[] * System.Threading.CancellationToken -> System.Threading.Tasks.Task<Azure.Security.KeyVault.Keys.Cryptography.VerifyResult>
override this.VerifyAsync : Azure.Security.KeyVault.Keys.Cryptography.SignatureAlgorithm * byte[] * byte[] * System.Threading.CancellationToken -> System.Threading.Tasks.Task<Azure.Security.KeyVault.Keys.Cryptography.VerifyResult>Public Overridable Function VerifyAsync (algorithm As SignatureAlgorithm, digest As Byte(), signature As Byte(), Optional cancellationToken As CancellationToken = Nothing) As Task(Of VerifyResult)Parameters
- algorithm
- SignatureAlgorithm
The SignatureAlgorithm to use. This must be the same algorithm used to sign the digest.
- digest
- Byte[]
The pre-hashed digest corresponding to the signature. The hash algorithm used to compute the digest must be compatible with the specified algorithm.
- signature
- Byte[]
The signature to verify.
- cancellationToken
- CancellationToken
A CancellationToken to cancel the operation.
Returns
The result of the verify operation. If the signature is valid the IsValid property of the returned VerifyResult will be set to true.
Exceptions
The specified algorithm does not match the key corresponding to the key identifier.
The local cryptographic provider threw an exception.
The key is invalid for the current operation.
The operation is not supported with the specified key.
The server returned an error. See Message for details returned from the server.
