/**
 * NMWepKeyType:
 * @NM_WEP_KEY_TYPE_UNKNOWN: unknown WEP key type
 * @NM_WEP_KEY_TYPE_KEY: indicates a hexadecimal or ASCII formatted WEP key.
 * Hex keys are either 10 or 26 hexadecimal characters (ie "5f782f2f5f" or
 * "732f2d712e4a394a375d366931"), while ASCII keys are either 5 or 13 ASCII
 * characters (ie "abcde" or "blahblah99$*1").
 * @NM_WEP_KEY_TYPE_PASSPHRASE: indicates a WEP passphrase (ex "I bought a duck
 * on my way back from the market 235Q&^%^*%") instead of a hexadecimal or ASCII
 * key.  Passphrases are between 8 and 64 characters inclusive and are hashed
 * the actual WEP key using the MD5 hash algorithm.
 * @NM_WEP_KEY_TYPE_LAST: placeholder value for bounds-checking
 *
 * The #NMWepKeyType values specify how any WEP keys present in the setting
 * are intepreted.  There are no standards governing how to hash the various WEP
 * key/passphrase formats into the actual WEP key.  Unfortunately some WEP keys
 * can be interpreted in multiple ways, requring the setting to specify how to
 * interpret the any WEP keys.  For example, the key "732f2d712e4a394a375d366931"
 * is both a valid Hexadecimal WEP key and a WEP passphrase.  Further, many
 * ASCII keys are also valid WEP passphrases, but since passphrases and ASCII
 * keys are hashed differently to determine the actual WEP key the type must be
 * specified.
