Password scrambler

Small utility to generate complicated passwords
(see also the GUI edition: https://hasherezade.github.io/passcrambler/ )

Benefits

• You get more secure password- long, not from dictionary, etc i.e 'txork9Zfa8yXc_lMbb1LCHPZIH7wE1'
  
• Yet, you don't have to remeber it - you must remember only your easy password and document that you used as a generation base
  
• You may reuse the easy password and the base file - still, for different login@domain you will get a totally new long password
• It is not saving your complicated password anywhere, so nobody can steal it and decrypt - it generates it by hasing function and you just need to copy it and login where you want
  
• Open source, written in python - nothing is hidden under the hood, everyone can review it before using and make custom changes in code

                         sha3_256,sha3_384,sha3_512,sha512,shake_128,shake_256}

Typical scenario:

• I need to generate a new password i.e. for my e-mail
• I have to prepare 2 things : an easy password, that I will remember and some document, that I have to keep safe without changes
• I deploy password scrambler giving as an input my login and a document
• I am prompted for the easy password, so I type it
• I copy generated password and change it in my e-mail service
• Wherever I need to re-login I just deploy scrambler with same parameters, and it will regenerate the same hash
