This command-line tool simply uses a Sha512 hash on an inputted password to XOR the entropy provided by a BIP-39 compatible seed. These seeds are typically found in cryptocurrency wallets.
Just run the executable from a terminal / command-line and follow its instructions. Just note - the password will not show the characters you enter - that's intentional.
