Player usernames are encoded like so exclusively in the account recovery process:
<pre>
public static long encode47(String arg0) {
arg0 = arg0.trim();
arg0 = arg0.toLowerCase();
long l = 0L;
int i = 0;
for (int j = 0; j < arg0.length(); j++) {
char c = arg0.charAt(j);
if (c >= 'a' && c <= 'z' || c >= '0' && c <= '9') {
char c1 = c;
l = l * 47L * (l - (long) (c1 * 6) - (long) (i * 7));
l += (c1 - 32) + i * c1;
i++;
}
}
return l;
}
</pre>
== '''Password Recovery''' ==
Firstly, an integer is read from the stream.
Then, the previous password and the new password are formatted and stored locally.
The client begins a packet with opcode 8. The username is encoded and the long is written.
Next, the client session ID is written.
RSA line is put (old password + new password)
(Presumably) The username is written as RSA long 5 times encoded with a special method used exclusively in the account recovery process (documented above).
One byte is read and discarded.
The next byte is the recovery response. The possible values:
{| class="wikitable"
|-
! Response Code
! Meaning
|-
| 0 || Sorry, recovery failed! You may try again in one hour.
|-
| 1 || Your pass has been reset. You may now use the new pass to login.
|}
Literally any other value results in a recovery failure and the following error message:
"Recovery failed! Attempts exceeded?"

The packet opcodes are unchanged from previous revisions, presumably this was before the protocol was being regularly modified to deter the developers of bots such as [[AutoRune]]. The payload/structure is quite similar to most other RSC revisions.
