Recently for one on my assignments I had to take a list of hashes and crack them using John the Ripper. Due to some shenanigans I couldn’t get access to the list of hashes. while trying to replicate the results I stumbles across the hashing function in the Linux terminal.

Example
$ echo -n "secret1" | sha256sum
5b11618c2e44027877d0cd0921ed166b9f176f50587fc91e7534dd2946db77d6

Not sure how useful this is an everyday use but it was there for me in my time of need haha.
