(Visual FoxPro) Example: Crypt2.ClearEncryptCerts methodDemonstrates how to call the ClearEncryptCerts method.
LOCAL loCrypt LOCAL loCert1 LOCAL loCert2 LOCAL loCert3 LOCAL loBd LOCAL lnSuccess LOCAL loCert4 LOCAL loCert5 loCrypt = CreateObject('Chilkat.Crypt2') * Tell the crypt object to use 3 certificates. * Do this by calling AddEncryptCert for each certificate. loCert1 = CreateObject('Chilkat.Cert') * ... * Load the cert from a source such as a .pfx/.p12 file, smart card, USB token, Apple keychain, Windows certificate store, etc. * ... loCrypt.AddEncryptCert(loCert1) loCert2 = CreateObject('Chilkat.Cert') * ... loCrypt.AddEncryptCert(loCert2) loCert3 = CreateObject('Chilkat.Cert') * ... loCrypt.AddEncryptCert(loCert3) * Params for public-key encryption to create PKCS7 enveloped-data loCrypt.CryptAlgorithm = "pki" loCrypt.Pkcs7CryptAlg = "aes" loCrypt.KeyLength = 256 loCrypt.OaepHash = "sha256" loCrypt.OaepPadding = 1 loBd = CreateObject('Chilkat.BinData') * ... lnSuccess = loCrypt.EncryptBd(loBd) * Let's say we now want to encrypt something else with different certs.. * First clear the encryption certs. loCrypt.ClearEncryptCerts() loCert4 = CreateObject('Chilkat.Cert') * ... loCrypt.AddEncryptCert(loCert4) loCert5 = CreateObject('Chilkat.Cert') * ... loCrypt.AddEncryptCert(loCert5) * ... * ... * Encrypt using cert4 and cert5. lnSuccess = loCrypt.EncryptBd(loBd) RELEASE loCrypt RELEASE loCert1 RELEASE loCert2 RELEASE loCert3 RELEASE loBd RELEASE loCert4 RELEASE loCert5 |
