Noob: DES-OFB key recovery w/known contents

[Davidi74]

Hi all.

I am new to HashCat and have been trying to figure out how to get Hashcat to recovery the encryption key when I know the original contents and encrypted contents..

Also too the files a have are all HEX files (as is the key and Init vector) if that complicates things any?

I hope someone smarter than me can point me in the right direction, I have tried the usual googling/youtubing, but I'm not finding what I'm after. Sorry if this has been asked before.

Thanks

Dave.

Thanks for your reply.

I guess thats why I couldn't figure out how to do it
