How change between gpu and/or gpu | change hash-type

[matt99]

I heard, that you can use hashcat with cpu and/or gpu. Depends this on the hashcat "version" (i mean hashcat, oclHashcat, and so)? If so, how can i decide between cpu, gpu and both? Is there any parameter for this?
I saw [url=https://hashcat.net/forum/thread-2302.htmlthis[/url] Thread and wonder, if its now the same. If not, where's the differences between all Hashcats now?
Also: Is there anything to consider, when i try to hash md5 or sha256/512 password? Or are the commands the same and hashcat knows the hash-type because of the hash character length?

The thread you linked to is nearly 4 years old, and not at all applicable to using hashcat in 2017. There is only one hashcat now, and it supports everything that hashcat-cli, oclHashcat, oclHashcat-plus, and oclHashcat-lite supported. All you need is an OpenCL runtime for each device you want to use (CPU, GPU, etc.) You can tell hashcat which device(s) and platform(s) you want to use via the -d and -D switches. It's that simple.
