NSFilemanager and secure delete

Is there any officially supported way of secure-deleting files in Mac OS X 10.5+?

if not, what about if I move all files (using NSFilemanager) to a common folder, and use srm: from a shell script. Would this delete all traces of a file, or would the file still be recoverable because of the move operation?

thanks in advance for any help/suggestions.

You can use:

NSError *err;
NSFileManager *fileManager = [[NSFileManager alloc] init];
[fileManager removeItemAtPath:path error:&err];

where path is a NSString with the path of the file you want to delete.

AFAIK, move isn't going to copy the bytes, just change the pointers in the file system.
