In other words, your password needs to be x/y times the size of the
secret
Say, we have a random value of 4 kilobits that someone wants
to keep secret by the means of protecting it with a password.
Empirical entropy estimate for an English text is 1.3 bits of
randomness per character, IIRC.
Assuming the password is an English word or a phrase, and the
secret is

Depends on the trust model. May not work.
This is incomplete. The
