CryptographyClient.VerifyAsync Method

Definition

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.
