When overridden in a derived class, computes the signature for the specified hash value using the specified padding.

Parameters

hash
Byte[]

The hash value of the data to be signed.

hashAlgorithm
HashAlgorithmName

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

padding
RSASignaturePadding

The padding.

Returns

Byte[]

The RSA signature for the specified hash value.

Exceptions

NotImplementedException

A derived class must override this method.

ArgumentNullException

hash or padding is null.

ArgumentException

hashAlgorithm.Name is null or Empty.

CryptographicException

padding is unknown, or not supported by this implementation.

-or-

This instance represents only a public key.
