Attempts to decrypt the input data using the specified padding mode, writing the result into a provided buffer.

override this.TryDecrypt : ReadOnlySpan<byte> * Span<byte> * System.Security.Cryptography.RSAEncryptionPadding * int -> boolPublic Overridable Function TryDecrypt (data As ReadOnlySpan(Of Byte), destination As Span(Of Byte), padding As RSAEncryptionPadding, ByRef bytesWritten As Integer) As BooleanParameters
- data
- ReadOnlySpan<Byte>
The data to decrypt.
- padding
- RSAEncryptionPadding
The padding mode.
- bytesWritten
- Int32
When this method returns, the total number of bytes written into destination. This parameter is treated as uninitialized.
Returns
true if destination is long enough to receive the decrypted data; otherwise, false.
Exceptions
padding is null.
padding is unknown, or not supported by this implementation.
-or-
The length of data is not equal to the number of bytes for KeySize.
-or-
This instance represents only a public key.
-or-
The decryption operation failed.
Remarks
The default implementation of this method calls Decrypt(Byte[], RSAEncryptionPadding) and copies the result to destination.
Derived types should override this method to avoid the intermediate array creation.
The RSA decryption algorithm will always produce an output smaller than the input, therefore this method will never return false when destination.Length >= data.Length.
