public key encryption related thread

this is awesome:

change:(NSDictionary *)change
context:(void *)context
{
NSIndexSet *indices = [change objectForKey:NSKeyValueChangeIndexesKey];
if (indices == nil)
return; // Nothing to do


// Build index paths from index sets
NSUInteger indexCount = [indices count];
NSUInteger buffer[indexCount];
[indices getIndexes:buffer maxCount:indexCount inIndexRange:nil];

NSMutableArray *indexPathArray = [NSMutableArray array];
for (int i = 0; i < indexCount; i++) {
NSUInteger indexPathIndices[2];
indexPathIndices[0] = 0;
indexPathIndices[1] = buffer[i];
NSIndexPath *newPath = [NSIndexPath indexPathWithIndexes:indexPathIndices length:2];
[indexPathArray addObject:newPath];
}

NSNumber *kind = [change objectForKey:NSKeyValueChangeKindKey];
if ([kind integerValue] == NSKeyValueChangeInsertion) // Rows were added
[self.tableView insertRowsAtIndexPaths:indexPathArray withRowAnimation:UITableViewRowAnimationFade];
else if ([kind integerValue] == NSKeyValueChangeRemoval) // Rows were removed
[self.tableView deleteRowsAtIndexPaths:indexPathArray withRowAnimation:UITableViewRowAnimationFade];
