---------

Contains authentication data, player per line.

||||
<name>:<password hash>:<privilege1,...>
|
||||
Format of password hash is <name><password> SHA1'd, in the base64 encoding.
|

|
||||
Legacy format (until 0.4.12) of password hash is <name><password> SHA1'd,
|
||||
in the base64 encoding.
|
||||
|
||||
Format (since 0.4.13) of password hash is #1#<salt>#<verifier>, with the parts inside <> encoded in the base64 encoding.
|
||||
<verifier> is an RFC 5054 compatible SRP-2048-SHA1 verifier
|
||||
of the given salt, password, and the player's name lowercased.
