possible to decrypt dahua hash?

[pay]

oclHashcat is OSS now should be easy to add

i am sorry but whats the meaning of OSS?

i wanted to add, its not only dahua.
they are lots of "community-enhanced"  in JTR  1.8.0-jumbo-1, that could be great if some how the users of hashcat could use scripts from JTR or implement all the scripts or some one them.
