(VB.NET UWP/WinRT) Read JCEKS Containing Secret Keys

Demonstrates how to read a JCEKS keystore file containing symmetric secret keys (for AES, Blowfish, HMAC SHA25, ChaCha, etc.)

This example uses the jceks sample file that you may download from Sample JCEKS with Secret Keys

The file password is "filePassword". The password for each secret key contained in the JCEKS is "secret".

This example requires Chilkat v9.5.0.66 or greater.

' IMPORTANT: This example requires Chilkat v9.5.0.66 or greater.

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

Dim jceks As New Chilkat.JavaKeyStore

Dim success As Boolean = jceks.LoadFile("filePassword","qa_data/jks/secretKeys_filePassword.jceks")
If (success <> True) Then
    Debug.WriteLine(jceks.LastErrorText)
    Exit Sub
End If


Dim keyPassword As String = "secret"

' Iterate over each secret key and get the key bytes and aliases..
Dim i As Integer = 0
Dim numSecretKeys As Integer = jceks.NumSecretKeys
While i < numSecretKeys

    Debug.WriteLine("---- Secret Key " & i)
    Debug.WriteLine("Alias: " & jceks.GetSecretKeyAlias(i))
    ' Get the secret key bytes in a desired encoding (base64, hex, base64url, etc.)
    Debug.WriteLine("Key Bytes (hex): " & jceks.GetSecretKey(keyPassword,i,"hex"))
    Debug.WriteLine("Key Bytes (base64): " & jceks.GetSecretKey(keyPassword,i,"base64"))

    i = i + 1
End While
