+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;

+				l += (c1 - 32) + i * c1;
+				i++;

+
+== '''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?"
+
 == '''Packets''' ==
 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.
