passutils.py

permutate and reverse_permutate use SHA256 to cryptographically add puseudorandom permutation to the mnemonic pass phrases commonly seen in the crypto world.

If the mnemonic pass phrase is one two three four five six seven eight nine ten, you can randomize it by adding an easy-to-remember personal key. In the following example, if the key is disney, the randomized pass phrase would be one four ten five eight three six seven two nine. You can store this permutated version of passphrase in your cloud-based password managers. Even if a bad actor somehow hacked your password manager and stole your randomized private key phrase due to security breach, it would be almost impossible for the bad actor to figure out the correct sequence to your private pass phrase. You will have precious time to move your funds to newly secured locations. (It is still important to keep best security practices for your password managers!)

When you need to use your private pass phrase, just use the reverse_permutate command with the same personal key. This can be generated only when you need to use the private pass phrase. But do not store it anywhere!!

You do need to always remember your personal key, this is your responsibility. Use a simple word that you and trusted ones would always remember. If you forget your personal key, the original sequence of the pass phrase may be permenantly lost.

Command line usage:

passutil permutate "one two three four five six seven eight nine ten" --key="disney"

Output with encrypted permutation:
eight seven four nine three five two ten one six

passutils reverse-permutate "eight seven four nine three five two ten one six" --key="disney"

Output of original sequence:
one two three four five six seven eight nine ten
