A hash is a string or number generated from a string of text. The resulting string or number is a fixed length, and will vary widely with small variations in input. The best hashing algorithms are designed so that it's impossible to turn a hash back into its original string.Hashing is an ideal way to store passwords, as hashes are inherently one-way in their nature. By storing passwords in hash format, it's very difficult for someone with access to the raw data to reverse it (assuming a strong hashing algorithm and appropriate salt has been used to generate it).Encryption turns data into a series of unreadable characters, that aren't of a fixed length. The key difference between encryption and hashing is that encrypted strings can be reversed back into their original decrypted form if you have the right key.Encryption should only ever be used over hashing when it is a necessity to decrypt the resulting message. For example, if you were trying to send secure messages to someone on the other side of the world, you would need to use encryption rather than hashing, as the message is no use to the receiver if they cannot decrypt it.
