Field Details

encryptedSecretKey

private final byte[] encryptedSecretKey

nonce

private final byte[] nonce

The nonce value.

Implementation Note:

This value is either encrypted (the left side of Either) or signed (the right side). If encrypted, then it must be done so using the server's public key and the server verifies it by decrypting and comparing nonces. If signed, then it must be done so using the user's private key provided from Mojang's server, and the server verifies by checking if the reconstructed data can be verified using the public key.
