Important

Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.

Overloads

DecryptAsync(EncryptionAlgorithm, Byte[], CancellationToken)	Decrypts the specified ciphertext.
DecryptAsync(DecryptParameters, CancellationToken)	Decrypts ciphertext.

DecryptAsync(EncryptionAlgorithm, Byte[], CancellationToken)

Source:: CryptographyClient.cs

Source:: CryptographyClient.cs

Decrypts the specified ciphertext.

public virtual System.Threading.Tasks.Task<Azure.Security.KeyVault.Keys.Cryptography.DecryptResult> DecryptAsync(Azure.Security.KeyVault.Keys.Cryptography.EncryptionAlgorithm algorithm, byte[] ciphertext, System.Threading.CancellationToken cancellationToken = default);

abstract member DecryptAsync : Azure.Security.KeyVault.Keys.Cryptography.EncryptionAlgorithm * byte[] * System.Threading.CancellationToken -> System.Threading.Tasks.Task<Azure.Security.KeyVault.Keys.Cryptography.DecryptResult>
override this.DecryptAsync : Azure.Security.KeyVault.Keys.Cryptography.EncryptionAlgorithm * byte[] * System.Threading.CancellationToken -> System.Threading.Tasks.Task<Azure.Security.KeyVault.Keys.Cryptography.DecryptResult>

Public Overridable Function DecryptAsync (algorithm As EncryptionAlgorithm, ciphertext As Byte(), Optional cancellationToken As CancellationToken = Nothing) As Task(Of DecryptResult)

Parameters

algorithm: EncryptionAlgorithm

The EncryptionAlgorithm to use.

ciphertext: Byte[]

The encrypted data to decrypt.

cancellationToken: CancellationToken

A CancellationToken to cancel the operation.

Returns

Task<DecryptResult>

The result of the decrypt operation. The returned DecryptResult contains the encrypted data along with information regarding the algorithm and key used to decrypt it.

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.

Applies to

DecryptAsync(DecryptParameters, CancellationToken)

Source:: CryptographyClient.cs

Source:: CryptographyClient.cs

Decrypts ciphertext.

public virtual System.Threading.Tasks.Task<Azure.Security.KeyVault.Keys.Cryptography.DecryptResult> DecryptAsync(Azure.Security.KeyVault.Keys.Cryptography.DecryptParameters decryptParameters, System.Threading.CancellationToken cancellationToken = default);

abstract member DecryptAsync : Azure.Security.KeyVault.Keys.Cryptography.DecryptParameters * System.Threading.CancellationToken -> System.Threading.Tasks.Task<Azure.Security.KeyVault.Keys.Cryptography.DecryptResult>
override this.DecryptAsync : Azure.Security.KeyVault.Keys.Cryptography.DecryptParameters * System.Threading.CancellationToken -> System.Threading.Tasks.Task<Azure.Security.KeyVault.Keys.Cryptography.DecryptResult>

Public Overridable Function DecryptAsync (decryptParameters As DecryptParameters, Optional cancellationToken As CancellationToken = Nothing) As Task(Of DecryptResult)

Parameters

decryptParameters: DecryptParameters

A DecryptParameters containing the data to decrypt and other parameters for algorithm-dependent decryption.

cancellationToken: CancellationToken

A CancellationToken to cancel the operation.

Returns

Task<DecryptResult>

The result of the decrypt operation. The returned DecryptResult contains the encrypted data along with information regarding the algorithm and key used to decrypt it.
