(Lianja) Generate an RSA Key and Get as Base64 DERDemonstrates how to generate a 2048-bit RSA key and return the public and private parts as unencrypted Base64 encoded DER. Note: This example requires Chilkat v11.0.0 or greater.
llSuccess = .F. // This example assumes the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. loRsa = createobject("CkRsa") // Generate a 2048-bit key. loPrivKey = createobject("CkPrivateKey") llSuccess = loRsa.GenKey(2048,loPrivKey) if (llSuccess = .F.) then ? loRsa.LastErrorText release loRsa release loPrivKey return endif // Get the public part of the key. loPubKey = createobject("CkPublicKey") loPrivKey.ToPublicKey(loPubKey) // There are two possible formats for representing the RSA public key // in ASN.1 (DER). The possible formats are PKCS1 and PKCS8. // We can get either by setting bChoosePkcs1 to .T. or .F.. llBChoosePkcs1 = .T. lcPubKeyBase64Der = loPubKey.GetEncoded(llBChoosePkcs1,"base64") ? "Public Key Base64 DER:" ? lcPubKeyBase64Der // Get the private key as Base64 DER: // We can get PKCS1 or PKCS8, but with different methods: lcPrivKeyPkcs1 = loPrivKey.GetPkcs1ENC("base64") ? "Private Key PKCS1 Base64 DER:" ? lcPrivKeyPkcs1 lcPrivKeyPkcs8 = loPrivKey.GetPkcs8ENC("base64") ? "Private Key PKCS8 Base64 DER:" ? lcPrivKeyPkcs8 release loRsa release loPrivKey release loPubKey |
