Load Certificate from PFX (PKCS#12)

Loads a digital certificate (and private key, if available) from a PFX file.(also known as PKCS#12)

LOCAL loCert
LOCAL lnSuccess
LOCAL lcPfxFilename
LOCAL lcPfxPassword
LOCAL loPrivKey
LOCAL lcPemPassword
LOCAL lcPemPath

loCert = CreateObject('Chilkat.Cert')

*  Load from the PFX file

lcPfxFilename = "/Users/chilkat/testData/pfx/chilkat_ssl_pwd_is_test.pfx"

lcPfxPassword = "test"

*  A PFX typically contains certificates in the chain of authentication.
*  The Chilkat cert object will choose the certificate w/
*  private key farthest from the root authority cert.
*  To access all the certificates in a PFX, use the
*  Chilkat certificate store object instead.
lnSuccess = loCert.LoadPfxFile(lcPfxFilename,lcPfxPassword)
IF (lnSuccess <> 1) THEN
    ? loCert.LastErrorText
    QUIT
ENDIF

*  Get some information about the digital certificate,
*  then get the private key...

*  DN = "Distinguished Name"
? "SubjectDN:" + loCert.SubjectDN

? "Common Name:" + loCert.SubjectCN
? "Issuer Common Name:" + loCert.IssuerCN

? "Serial Number:" + loCert.SerialNumber

*  Now for the private key...

loPrivKey = loCert.ExportPrivateKey()
IF (loPrivKey = NULL ) THEN
    ? loCert.LastErrorText
    QUIT
ENDIF

*  The private key object may be used in any Chilkat methods
*  (in other objects/classes) that expect a private key argument.

*  In this case, save the private key to a PKCS8 Encrypted PEM format file:

lcPemPassword = "secret"

lcPemPath = "/Users/chilkat/testData/pem/chilkat_privKey.pem"
lnSuccess = loPrivKey.SavePkcs8EncryptedPemFile(lcPemPassword,lcPemPath)
IF (lnSuccess <> 1) THEN
    ? loPrivKey.LastErrorText
    RELEASE loPrivKey
    QUIT
ENDIF

RELEASE loPrivKey
? "Private key saved to PKCS8 Encrypted PEM..."
