Visual basic 6.0 - ComputeHash invalid procedure call or argument error
- by Mohan Babu Vijaya Gopal
I am getting the error "invalid procedure call or arguments" at the step computeHash().
Any help highly appreciated.
Private Sub Form_Load()

'u8 = Encoding.UTF8
Dim minSaltSize As Integer
Dim maxSaltSize As Integer
Dim saltSize As Integer
minSaltSize = 4
maxSaltSize = 8
Dim randm As Random
Set randm = New Random
Dim saltBytes() As Byte
ReDim saltBytes(saltSize)
Set rngcsp = New RNGCryptoServiceProvider
rngcsp.GetNonZeroBytes (saltBytes)
Dim plainTextBytes() As Byte
plainTextBytes() = ConvertStringToUtf8Bytes("Mohan")
Dim plainTextBytesLen As Long
plainTextBytesLen = UBound(plainTextBytes) - LBound(plainTextBytes) + 1
Dim saltBytesLen As Long
saltBytesLen = UBound(saltBytes) - LBound(saltBytes) + 1
Dim plainTextWithSaltBytes() As Byte
ReDim plainTextWithSaltBytes(plainTextBytesLen + saltBytesLen)
For i = 0 To plainTextBytesLen - 1
plainTextWithSaltBytes(i) = plainTextBytes(i)
Next
For i = 0 To saltBytesLen - 1
plainTextWithSaltBytes(i) = saltBytes(i)
Next
'Dim hash As HashAlgorithm = New MD5CryptoServiceProvider()

Dim totLen As Integer
totLen = plainTextBytesLen + saltBytesLen
Dim str As String
Dim hashBytes() As Byte
'With
hashBytes = hash12.computeHash(plainTextWithSaltBytes) ', 0, totLen)
'End With
End Sub
