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.

Attempts to hash the provided data with the specified algorithm and sign the hash with the current key, writing the signature into a provided buffer.

public:
 virtual bool TrySignData(ReadOnlySpan<System::Byte> data, Span<System::Byte> destination, System::Security::Cryptography::HashAlgorithmName hashAlgorithm, System::Security::Cryptography::RSASignaturePadding ^ padding, [Runtime::InteropServices::Out] int % bytesWritten);

public virtual bool TrySignData(ReadOnlySpan<byte> data, Span<byte> destination, System.Security.Cryptography.HashAlgorithmName hashAlgorithm, System.Security.Cryptography.RSASignaturePadding padding, out int bytesWritten);

abstract member TrySignData : ReadOnlySpan<byte> * Span<byte> * System.Security.Cryptography.HashAlgorithmName * System.Security.Cryptography.RSASignaturePadding * int -> bool
override this.TrySignData : ReadOnlySpan<byte> * Span<byte> * System.Security.Cryptography.HashAlgorithmName * System.Security.Cryptography.RSASignaturePadding * int -> bool

Public Overridable Function TrySignData (data As ReadOnlySpan(Of Byte), destination As Span(Of Byte), hashAlgorithm As HashAlgorithmName, padding As RSASignaturePadding, ByRef bytesWritten As Integer) As Boolean

Parameters

data: ReadOnlySpan<Byte>

The input data to hash and sign.

destination: Span<Byte>

The buffer to receive the RSA signature.

hashAlgorithm: HashAlgorithmName

The hash algorithm used to create the hash value of the data.

padding: RSASignaturePadding

The padding mode.

bytesWritten: Int32

When this method returns, the total number of bytes written into destination. This parameter is treated as uninitialized.

Returns

Boolean

true if destination is long enough to receive the RSA signature; otherwise, false.

Exceptions

ArgumentNullException

padding is null.

ArgumentException

hashAlgorithm.Name is null or Empty.

CryptographicException

This instance represents only a public key.

-or-

An error occurred creating the signature.

Remarks

The RSA signature algorithm will always produce an output equal to the number of bytes required for KeySize bits.
