Dim success As Boolean
success = False

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// Load an RSA private key for signing.
Dim privKey As New Chilkat.PrivateKey
success = privKey.LoadEncryptedPemFile("qa_data/pem/rsa_passwd.pem","passwd")
If (success = False) Then
    System.DebugLog(privKey.LastErrorText)
    Return
End If

Dim rsa As New Chilkat.Rsa
success = rsa.UsePrivateKey(privKey)
If (success = False) Then
    System.DebugLog(rsa.LastErrorText)
    Return
End If

Dim originalData As String
originalData = "This is the string to be hashed an RSA signed."

// Indicate that we want the utf-8 byte representation of the string to be signed
rsa.Charset = "utf-8"

// We want the RSA signature in base64 format
rsa.EncodingMode = "base64"

Dim sigBase64 As String
sigBase64 = rsa.SignStringENC(originalData,"sha256")
System.DebugLog(sigBase64)
