Read JCEKS Containing Secret Keys

See more Java KeyStore (JKS) Examples

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.

const std = @import("std");
const chilkat = @import("chilkat");

pub fn main(init: std.process.Init) !void {
    const alloc = init.arena.allocator();

    // 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.

    const jceks = try chilkat.JavaKeyStore.init();
    defer jceks.deinit();

    jceks.loadFile("filePassword", "qa_data/jks/secretKeys_filePassword.jceks") catch {
        std.debug.print("{s}\n", .{try jceks.getLastErrorText(alloc)});
        return;
    };

    const key_password = "secret";

    // Iterate over each secret key and get the key bytes and aliases..
    var i: i32 = 0;
    const num_secret_keys = jceks.getNumSecretKeys();
    while (i < num_secret_keys) {
        std.debug.print("---- Secret Key {d}\n", .{i});
        std.debug.print("Alias: {s}\n", .{try jceks.getSecretKeyAlias(alloc, i)});
        // Get the secret key bytes in a desired encoding (base64, hex, base64url, etc.)
        std.debug.print("Key Bytes (hex): {s}\n", .{try jceks.getSecretKey(alloc, key_password, i, "hex")});
        std.debug.print("Key Bytes (base64): {s}\n", .{try jceks.getSecretKey(alloc, key_password, i, "base64")});

        i = i + 1;
    }

    // The output:
