45 | * Create a {@link RemoteLibrary} linked to the given server. | |
46 | * <p> | |
47 | * Note that the key is structured: | |
48 | * <tt><b><i>xxx</i></b>(|<b><i>yyy</i></b>|<b>wl</b>)(|<b>rw</b>)</tt> | |
49 | * <p> | |
50 | * Note that anything before the first pipe (<tt>|</tt>) character is | |
51 | * considered to be the encryption key, anything after that character is | |
52 | * called the subkey (including the other pipe characters and flags!). | |
53 | * <p> | |
54 | * This is important because the subkey (including the pipe characters and | |
55 | * flags) must be present as-is in the server configuration file to be | |
56 | * allowed. | |
57 | * <ul> | |
58 | * <li><b><i>xxx</i></b>: the encryption key used to communicate with the | |
59 | * server</li> | |
60 | * <li><b><i>yyy</i></b>: the secondary key</li> | |
61 | * <li><b>rw</b>: flag to allow read and write access if it is not the | |
62 | * default on this server</li> | |
63 | * <li><b>wl</b>: flag to allow access to all the stories (bypassing the | |
64 | * whitelist if it exists)</li> | |
65 | * </ul> | |
66 | * <p> | |
67 | * Some examples: | |
68 | * <ul> | |
69 | * <li><b>my_key</b>: normal connection, will take the default server | |
70 | * options</li> | |
71 | * <li><b>my_key|agzyzz|wl</b>: will ask to bypass the white list (if it | |
72 | * exists)</li> | |
73 | * <li><b>my_key|agzyzz|rw</b>: will ask read-write access (if the default | |
74 | * is read-only)</li> | |
75 | * <li><b>my_key|agzyzz|wl|rw</b>: will ask both read-write access and white | |
76 | * list bypass</li> | |
77 | * </ul> | |
78 | * | |
79 | * @param key | |
80 | * the key that will allow us to exchange information with the | |
81 | * server | |
82 | * @param host | |
83 | * the host to contact or NULL for localhost | |
84 | * @param port | |
85 | * the port to contact it on | |
