Post: RE: need help with sha512

yes, i mean hardware. the problem is sha512 requires much more vram than the other hash types, hence the out of resources error.

sha512 hashes in linux shadow file is actually sha512crypt, not raw sha512.

Post: RE: need help with sha512

Please understand sha512crypt, aka SHA512(Unix), is *not* simply salted sha512. The "hex string" generated by Cain's Hash Calculator is just a raw sha512 hash, and is completely different -- and in no...

right. you're using shared resources, and most vps providers make heavy use of oversubscription so that they can put a large number of virtual machines on a single host. you're probably only getting 1...
