Dim success As Boolean = False

'  On MacOS or iOS, this searches both the Default keychains and System keychains for the certificate
'  having the specified CN.
Dim cert As ChilkatCert

Log(cert.SubjectDN)

'  Note: In the Apple Keychain, a certificate with its private key represents an identity because it combines the certificate and its private key.
'  When Chilkat loads a certificate from the Apple Keychain, it also gets the associated private key.
'  You can simply use the cert in other places in Chilkat where a cert w/ private key is required.
Dim cert2 As ChilkatCert
cert2.Initialize("cert2")
success = cert2.LoadByCommonName("Chilkat Software, Inc.")
If success = False Then
    Log(cert2.LastErrorText)
    Return
End If


Log(cert2.SubjectDN)
Dim hasPrivKey As Boolean = cert2.HasPrivateKey
Log("Has private key: " & hasPrivKey)
