CryptographyClient.VerifyAsync Method

Definition

Namespace:

Azure.Security.KeyVault.Keys.Cryptography

Assembly:

Azure.Security.KeyVault.Keys.dll

Package:

Azure.Security.KeyVault.Keys v4.7.0

Source:

CryptographyClient.cs

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

Task<VerifyResult>

The result of the verify operation. If the signature is valid the IsValid property of the returned VerifyResult will be set to true.

Exceptions

ArgumentException

The specified algorithm does not match the key corresponding to the key identifier.

CryptographicException

The local cryptographic provider threw an exception.

InvalidOperationException

The key is invalid for the current operation.

NotSupportedException

The operation is not supported with the specified key.

RequestFailedException

The server returned an error. See Message for details returned from the server.
