Definition
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.
Attempts to produce a "thumbprint" for the certificate by hashing the encoded representation of the certificate with the specified hash algorithm.
public:
virtual bool TryGetCertHash(System::Security::Cryptography::HashAlgorithmName hashAlgorithm, Span<System::Byte> destination, [Runtime::InteropServices::Out] int % bytesWritten);
public virtual bool TryGetCertHash (System.Security.Cryptography.HashAlgorithmName hashAlgorithm, Span<byte> destination, out int bytesWritten);
abstract member TryGetCertHash : System.Security.Cryptography.HashAlgorithmName * Span<byte> * int -> bool
override this.TryGetCertHash : System.Security.Cryptography.HashAlgorithmName * Span<byte> * int -> bool
Public Overridable Function TryGetCertHash (hashAlgorithm As HashAlgorithmName, destination As Span(Of Byte), ByRef bytesWritten As Integer) As Boolean
Parameters
- hashAlgorithm
- HashAlgorithmName
The algorithm to use for the thumbprint.
- 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 hash value; otherwise, false
.
Exceptions
hashAlgorithm
.Name is null
or an empty string.
hashAlgorithm
is not a known hash algorithm.
