Load Java KeyStore and Access Contents

See more Java KeyStore (JKS) Examples

Loads 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. Go

    success := false

    // This requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    jks := chilkat.NewJavaKeyStore()

    // 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 {
        fmt.Println(jks.LastErrorText())
        jks.DisposeJavaKeyStore()
        return
    }

    // Find out how many of each type of entry:
    numTrustedCerts := jks.NumTrustedCerts()
    numPrivateKeys := jks.NumPrivateKeys()

    cert := chilkat.NewCert()
    var alias string

    // For each trusted certificate, access it by getting
    // it as a cert object.  Also get the alias associated with the certificate.
    fmt.Println("Trusted Certs:")
    i := 0
    for i < numTrustedCerts {
        success = jks.TrustedCertAt(i,cert)
        fmt.Println(*jks.GetTrustedCertAlias(i), ": ", cert.SubjectDN())
        i = i + 1
    }

    privKey := chilkat.NewPrivateKey()
    certChain := chilkat.NewCertChain()

    // For each private key entry, get the private key and
    // the associated certificate chain.
    // Each private key is password protected.  Usually it is the same
    // password as used for the keyed digest of the entire JKS.  
    // However, this does not have to be.  The password is passed
    // here to handle the possibility of each private key requiring
    // a different password.
    fmt.Println("Private Keys:")
    i = 0
    for i < numPrivateKeys {
        jks.PrivateKeyAt("jksFilePassword",i,privKey)
        fmt.Println(*jks.GetPrivateKeyAlias(i))
        jks.CertChainAt(i,certChain)

        // The 1st certificate in the chain is the one associated with the private key.
        certChain.CertAt(0,cert)
        fmt.Println(cert.SubjectDN())

        i = i + 1
    }
