(Xojo Plugin) Load Java KeyStore and Access ContentsLoads a Java keystore file and iterates over the contents. A Java keystore (.jks) file can contain one or more trusted root certificate entries and/or one or more private key entries. Each private key entry includes an associated certificate chain. Note: This example requires Chilkat v11.0.0 or greater.
Dim success As Boolean success = False // This requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. Dim jks As New Chilkat.JavaKeyStore // Load the Java keystore from a file. The JKS file password is used // to verify the keyed digest that is found at the very end of the keystore. // It verifies there has been no tampering with the file. success = jks.LoadFile("jksFilePassword","/someDir/keyStore.jks") If (success = False) Then System.DebugLog(jks.LastErrorText) Return End If // Find out how many of each type of entry: Dim numTrustedCerts As Int32 numTrustedCerts = jks.NumTrustedCerts Dim numPrivateKeys As Int32 numPrivateKeys = jks.NumPrivateKeys Dim cert As New Chilkat.Cert Dim alias As String // For each trusted certificate, access it by getting // it as a cert object.

The password is passed // here to handle the possibility of each private key requiring // a different password.
