One of the reasons you can’t set a password for a folder is that, if you use BitLocker to encrypt your entire device, your account is already secured against unauthorized access with a password and even encryption.

Is encryption the same as compression?

At its most basic level, compression seeks to utilize patterns in data to minimize its size. Without the key, patterns in the data can’t be detected at all, which is the goal of encryption. An output of encryption is a jumble of bits with a lot of entropy that appears random.

Which comes first encryption or compression?

first, compress. Your data becomes (basically) a stream of random bits when you encrypt it. Because compression looks for patterns in the data, and a random stream by definition lacks patterns, random bits cannot be compressed.

Do salts protect weak passwords?

A top priority is making sure that your passwords and data are secure. The highest level of protection is provided by hashing, salting, and cryptographic hash functions for passwords. Even the most powerful password attacks can be successfully repelled by adding salt to your password.

Can two passwords have same hash?

Hash collisions, which occur when two passwords generate the same hash, are known. In this instance, logging into the relevant account is possible using both passwords. For the majority of hashing algorithms, it’s extremely unlikely to occur, but it might.
