Public Function SignHash (rgbHash As Byte(), str As String) As Byte()
Parameters
- rgbHash
- Byte[]
The hash value of the data to be signed.
- str
- String
The name of the hash algorithm used to create the hash value of the data.
Returns
The DSA signature for the specified hash value.
Exceptions
The rgbHash
parameter is null
.
The cryptographic service provider (CSP) cannot be acquired.
-or-
There is no private key.
Remarks
This method creates a digital signature that is verified using the VerifyHash method.
DSA uses the SHA1 hash algorithm.
