(VBScript) RSA Sign utf-8 Byte Representation of String
Demontstrates how to sign the utf-8 byte representation of a string.
Dim fso, outFile
Set fso = CreateObject("Scripting.FileSystemObject")
Set outFile = fso.CreateTextFile("output.txt", True)
' 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.
set privKey = CreateObject("Chilkat_9_5_0.PrivateKey")
success = privKey.LoadEncryptedPemFile("qa_data/pem/rsa_passwd.pem","passwd")
If (success <> 1) Then
outFile.WriteLine(privKey.LastErrorText)
WScript.Quit
End If
set rsa = CreateObject("Chilkat_9_5_0.Rsa")
success = rsa.ImportPrivateKeyObj(privKey)
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"
sigBase64 = rsa.SignStringENC(originalData,"sha256")
outFile.WriteLine(sigBase64)
outFile.Close
