thank you, etotheipi, I stand corrected. I wanted to help too quickly last night
And yes, I am reverse engineering the shit out of the Armory code, tx files and wallets since several weeks lately, I hope I can present soon what for
I took another 30 mins and wrote a (now tested and working) import function in PHP:
Code:
function import_watchonly_wallet($root_id, $root_data)
{
$nc = array(' '=>'',
'a'=>'0', 's'=>'1', 'd'=>'2', 'f'=>'3',
'g'=>'4', 'h'=>'5', 'j'=>'6', 'k'=>'7',
'w'=>'8', 'e'=>'9', 'r'=>'a', 't'=>'b',
'u'=>'c', 'i'=>'d', 'o'=>'e', 'n'=>'f');
foreach($nc as $easy16 => $normal) {
$root_id = str_replace($easy16, $normal, $root_id);
$root_data = str_replace($easy16, $normal, $root_data);
}
$sign = gmp_strval(gmp_and(gmp_init(substr($root_id, 0, 2), 16), gmp_init('80', 16))) ? '03' : '02';
$x_coord = substr($root_data, 0, 32).substr($root_data, 36, 32);
$rootpubkey = BitcoinLib::decompress_public_key($sign.$x_coord);
$chaincode = substr($root_data, 72, 32).substr($root_data, 108, 32);
return array('rootpubkey' => $rootpubkey['public_key'],
'chaincode' => $chaincode);
}
{
$nc = array(' '=>'',
'a'=>'0', 's'=>'1', 'd'=>'2', 'f'=>'3',
'g'=>'4', 'h'=>'5', 'j'=>'6', 'k'=>'7',
'w'=>'8', 'e'=>'9', 'r'=>'a', 't'=>'b',
'u'=>'c', 'i'=>'d', 'o'=>'e', 'n'=>'f');
foreach($nc as $easy16 => $normal) {
$root_id = str_replace($easy16, $normal, $root_id);
$root_data = str_replace($easy16, $normal, $root_data);
}
$sign = gmp_strval(gmp_and(gmp_init(substr($root_id, 0, 2), 16), gmp_init('80', 16))) ? '03' : '02';
$x_coord = substr($root_data, 0, 32).substr($root_data, 36, 32);
$rootpubkey = BitcoinLib::decompress_public_key($sign.$x_coord);
$chaincode = substr($root_data, 72, 32).substr($root_data, 108, 32);
return array('rootpubkey' => $rootpubkey['public_key'],
'chaincode' => $chaincode);
}
You can use it like this now:
Code:
$root_id = "wski edsj oose aafj tr";
$root_data = "kgei aokr eira ghst dfod utdf djte trot wggjtaiu grfr autk idre tugh sodi dwuk ffww sesnkoet hfgk tjhj kawf geds wgrn ehtt wofo fitakght nsgh ttet ntia gggk tjod unuk dgaw dahj";
$wallet = import_watchonly_wallet($root_id, $root_data);
$chaincode = $wallet['chaincode'];
$pubkey = $wallet['rootpubkey'];
for($i = 0; $i < 10; $i++) {
$pubkey = compute_chained_pubkey($pubkey, $chaincode);
echo BitcoinLib::public_key_to_address($pubkey, '00');
echo "\n";
}
$root_data = "kgei aokr eira ghst dfod utdf djte trot wggjtaiu grfr autk idre tugh sodi dwuk ffww sesnkoet hfgk tjhj kawf geds wgrn ehtt wofo fitakght nsgh ttet ntia gggk tjod unuk dgaw dahj";
$wallet = import_watchonly_wallet($root_id, $root_data);
$chaincode = $wallet['chaincode'];
$pubkey = $wallet['rootpubkey'];
for($i = 0; $i < 10; $i++) {
$pubkey = compute_chained_pubkey($pubkey, $chaincode);
echo BitcoinLib::public_key_to_address($pubkey, '00');
echo "\n";
}
which actually spits out now

Have fun!
Btw, I would generate the rootpubkey and chaincode only once and store it somehow, then. You also do not have to start the generation again beginning with the root pubkey, just always store the last used pubkey and generate more from that point, this saves computation time.
