(Visual FoxPro) RSA Sign utf-8 Byte Representation of StringDemontstrates how to sign the utf-8 byte representation of a string. Note: This example requires Chilkat v11.0.0 or greater.
LOCAL lnSuccess LOCAL loPrivKey LOCAL loRsa LOCAL lcOriginalData LOCAL lcSigBase64 lnSuccess = 0 * 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.PrivateKey') lnSuccess = loPrivKey.LoadEncryptedPemFile("qa_data/pem/rsa_passwd.pem","passwd") IF (lnSuccess = 0) THEN ? loPrivKey.LastErrorText RELEASE loPrivKey CANCEL ENDIF loRsa = CreateObject('Chilkat.Rsa') loRsa.UsePrivateKey(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 RELEASE loPrivKey RELEASE loRsa |
