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.

destination: Span<Byte>

The buffer to receive the certificate thumbprint.

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 hash value; otherwise, false.

Exceptions

ArgumentException

hashAlgorithm.Name is null or an empty string.

CryptographicException

hashAlgorithm is not a known hash algorithm.
