Golf: tripcode searching

^{(Note: Anyone attempting to test tripcodes in this thread is a fucking idiot.)}

Let's see the shortest program to search for a tripcode containing a string in the language of your choice. Executing an existing tripcode searcher obviously doesn't count.

I'll start off with some __FIOC__:

t=lambda a,i=__import__:'#%s  !%s'%next(i('itertools').dropwhile(lambda v:a
not in v[1].lower(),iter(lambda:(lambda k:(k,i('crypt').crypt(k,k[1:])[3:]))
(''.join(chr(i('random').randint(32,126))for n in range(8))),None)))
# And to run it:
print(t('abc'))
