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.

override this.TrySignData : ReadOnlySpan<byte> * Span<byte> * System.Security.Cryptography.HashAlgorithmName * System.Security.Cryptography.RSASignaturePadding * int -> boolPublic Overridable Function TrySignData (data As ReadOnlySpan(Of Byte), destination As Span(Of Byte), hashAlgorithm As HashAlgorithmName, padding As RSASignaturePadding, ByRef bytesWritten As Integer) As BooleanParameters
- data
- ReadOnlySpan<Byte>
The input data to hash and sign.
- 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
true if destination is long enough to receive the RSA signature; otherwise, false.
Exceptions
padding is null.
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.
