public static byte[] encryptPassword(java.lang.CharSequence password, byte[] seed)
Encrypts a password.protocol for authentication is like this:

- client makes a sha1 digest of the password
- client hashes the output of 2
- client digests the seed
- client updates the digest with the output from 3
- an xor of the output of 5 and 2 is sent to server
- server does the same thing and verifies that the scrambled passwords match
- Parameters:
password
- the password to encryptseed
- the seed to use- Returns:
- a scrambled password
