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

Parameters

data
ReadOnlySpan<Byte>

The data to hash and sign.

destination
Span<Byte>

The byte span to receive the signature.

hashAlgorithm
HashAlgorithmName

The name of the hash algorithm to use.

bytesWritten
Int32

When this method returns, contains a value that indicates the number of bytes written to destination.

Returns

true if destination is large enough to receive the result; otherwise, false.

Public Function TrySignData (data As ReadOnlySpan(Of Byte), destination As Span(Of Byte), hashAlgorithm As HashAlgorithmName, signatureFormat As DSASignatureFormat, ByRef bytesWritten As Integer) As Boolean

Parameters

data
ReadOnlySpan<Byte>

The data to hash and sign.

destination
Span<Byte>

The buffer to receive the signature.

hashAlgorithm
HashAlgorithmName

The hash algorithm to use to create the hash value.

signatureFormat
DSASignatureFormat

The encoding format to use for the signature.

bytesWritten
Int32

When this method returns, contains a value that indicates the number of bytes written to destination. This parameter is treated as uninitialized.

Returns

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

Exceptions

signatureFormat is not a known format.

hashAlgorithm has a null or empty Name.

An error occurred in the signing operation.
