(Visual FoxPro) Generate RSA Key and return Base64 PKCS8 Private Key

Demonstrates how to generate a new 2048-bit RSA private key and returns the Base64 encoded PKCS8 representation of the private key.

Note: This example requires Chilkat v11.0.0 or greater.

LOCAL lnSuccess
LOCAL loRsa
LOCAL loPrivKey
LOCAL lcPrivKeyPkcs8Base64

lnSuccess = 0

loRsa = CreateObject('Chilkat.Rsa')

* Generate a 2048-bit key.  Chilkat RSA supports
* key sizes ranging from 512 bits to 8192 bits.
loPrivKey = CreateObject('Chilkat.PrivateKey')
lnSuccess = loRsa.GenKey(2048,loPrivKey)
IF (lnSuccess = 0) THEN
    ? loRsa.LastErrorText
    RELEASE loRsa
    RELEASE loPrivKey
    CANCEL
ENDIF

* Get the private key in PKCS8 Base64 format
lcPrivKeyPkcs8Base64 = loPrivKey.GetPkcs8ENC("base64")

* The key in base64 format will start similar to this:
* MIIEvAIBADANBgkqhkiG9w0BA...
? lcPrivKeyPkcs8Base64
