To generate these keys, I xor two values together. The methods that perform this operation yield the keySeed value. This operation was considered trivial and hence it isn’t disclosed in the code that I have quoted.

Using SHA1 keys, I go about calculating the key pair twice. I then compare the first key pair to the second and see if I get a true or a false answer.

I have tried a comparison using mock-up code, and I have disclosed the main method here. The code generates what I believed would be the same key pair twice and compares them…

        var arg1="65cfa78989387ca19f18d1d54af0d45dfb8fd9ee";
        var arg2="783C82C2E6394A329A8149564E1B6AB74AA70FBD";
        var keySeed=Sovereignty.bitwiseXor(Sovereignty.hexStringToByteArray(arg1),Sovereignty.hexStringToByteArray(arg2));

        SecureRandom random;
        try{
            random=SecureRandom.getInstance("SHA1PRNG");
        }catch(NoSuchAlgorithmException x){
            throw new RuntimeException(x);
        }

        // First key...
        
        random.setSeed(keySeed);

        KeyPairGenerator keyGen1;
        try{
            keyGen1=KeyPairGenerator.getInstance("DSA");
        }catch(NoSuchAlgorithmException x){
            throw new RuntimeException(x);
        }

        keyGen1.initialize(1024,random);
        
        var firstKey=keyGen1.generateKeyPair();

        // Second key...
        
        random.setSeed(keySeed);

        KeyPairGenerator keyGen2;
        try{
            keyGen2=KeyPairGenerator.getInstance("DSA");
        }catch(NoSuchAlgorithmException x){
            throw new RuntimeException(x);
        }

        keyGen2.initialize(1024,random);
        
        var secondKey=keyGen2.generateKeyPair();
        
        System.out.println(firstKey.getPublic().equals(secondKey.getPublic()));

However, the test on the final line returns false, when I am expecting it to return true.

What am I doing wrong?
