(Visual FoxPro) 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.

LOCAL loJceks
LOCAL lnSuccess
LOCAL lcKeyPassword
LOCAL i
LOCAL lnNumSecretKeys

*  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.

loJceks = CreateObject('Chilkat_9_5_0.JavaKeyStore')

lnSuccess = loJceks.LoadFile("filePassword","qa_data/jks/secretKeys_filePassword.jceks")
IF (lnSuccess <> 1) THEN
    ? loJceks.LastErrorText
    RELEASE loJceks
    CANCEL
ENDIF

lcKeyPassword = "secret"

*  Iterate over each secret key and get the key bytes and aliases..
i = 0
lnNumSecretKeys = loJceks.NumSecretKeys
DO WHILE i < lnNumSecretKeys

    ? "---- Secret Key " + STR(i)
    ? "Alias: " + loJceks.GetSecretKeyAlias(i)
    *  Get the secret key bytes in a desired encoding (base64, hex, base64url, etc.)
    ? "Key Bytes (hex): " + loJceks.GetSecretKey(lcKeyPassword,i,"hex")
    ? "Key Bytes (base64): " + loJceks.GetSecretKey(lcKeyPassword,i,"base64")

    i = i + 1
ENDDO

*  The output:

*  ---- Secret Key 0
*  Alias: aes_key
