WebAs many will know, one-way encryption is a handy way to encrypt user passwords in databases. That way, even the administrator of the database cannot know a user's password, but will have to take a password guess, encrypt that with the same algorithm and then compare the result with the encrypted password in the database. WebIn cryptography, a one-way compression function is a function that transforms two fixed-length inputs into a fixed-length output. [1] The transformation is "one-way", meaning that it is difficult given a particular output to compute inputs which compress to that output. north penn web mail
