-> Hashing is the process of mapping binary data of a variable length to a fixed size binary data.
-> One-way encryption
-> Common algorithms:
– MD5 (generates a 16 character hash that can be stored in a GUID)
– SHA (SHA1, SHA256, SHA384, SHA512)
-> Used of storing passwords, comparing files, data corruption/tamper checking
– Use SHA256 or greater for storing password.
