hashing
Important to use complex and unique passwords
Hashing algorithms always produce the same hash for the same password
Steps to «hacking»:
Compute the hash for «password»
Check if it matches with the hash that corresponds to you
If it does, your password is «password»
Rainbow tables and protection against them
Databases of hashes to common passwords
Answer to rainbow tables: «salt»
Pin = «0000», pin with salt = «0000B_of_A_salt»
Salt makes the passwords have an entirely different hash
Allows you to have much more combinations
