(Visual FoxPro) RSA Sign utf-8 Byte Representation of String
Demontstrates how to sign the utf-8 byte representation of a string.

* 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.
loPrivKey = CreateObject('Chilkat_9_5_0.PrivateKey')
lnSuccess = loPrivKey.LoadEncryptedPemFile("qa_data/pem/rsa_passwd.pem","passwd")
IF (lnSuccess <> 1) THEN
? loPrivKey.LastErrorText
RELEASE loPrivKey
CANCEL
ENDIF
loRsa = CreateObject('Chilkat_9_5_0.Rsa')
loRsa.ImportPrivateKeyObj(loPrivKey)
lcOriginalData = "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
loRsa.Charset = "utf-8"
* We want the RSA signature in base64 format
loRsa.EncodingMode = "base64"
lcSigBase64 = loRsa.SignStringENC(lcOriginalData,"sha256")
? lcSigBase64
