Example: Crypt2.GenRandomBytesENC method

Shows how to use the GenRandomBytesENC method to generate a specified number of random bytes and return them as a binary encoded string, such as in base64 or hex format. Chilkat2 Java

import com.chilkatsoft.chilkat2.Crypt2;

public class ChilkatExample {

    public static void main(String[] args) {
        Crypt2 crypt = new Crypt2();

        // Example of a some of the binary encodings supported by Chilkat.

        // Internally uses the Fortuna cryptographically secure random number generation algorithm
        // auto-seeded from a secure source of entropy that depends on the OS.

        crypt.setEncodingMode("hex");
        String s = crypt.genRandomBytesENC(8);
        System.out.println("Uppercase Hex: " + s);

        crypt.setEncodingMode("hex_lower");
        s = crypt.genRandomBytesENC(8);
        System.out.println("Lowercase Hex: " + s);

        crypt.setEncodingMode("base64");
        s = crypt.genRandomBytesENC(8);
        System.out.println("Base64: " + s);

        crypt.setEncodingMode("base64url");
        s = crypt.genRandomBytesENC(8);
        System.out.println("Base64Url: " + s);

        crypt.setEncodingMode("base58");
        s = crypt.genRandomBytesENC(8);
        System.out.println("Base58: " + s);

        crypt.setEncodingMode("base32");
        s = crypt.genRandomBytesENC(8);
        System.out.println("Base32: " + s);

        crypt.setEncodingMode("decList");
        s = crypt.genRandomBytesENC(8);
        System.out.println("Decimal List: " + s);
