Hashing	Encryption
It is a method of converting data to a smaller fixed value known as the key, which is then used to represent the original data.	It’s the technique of securely encoding data such that only the authorized user with the key or password can get the original data; for everyone else, it seems to be rubbish.
By whatever method, the hash code or key cannot be reverted to the original information. It can only be mapped, and the hash code is compared; if the hash code is the same, the information is identical; otherwise, it is not. It is not possible to get the original data.	If we know the encryption key and technique used for encryption, we can easily extract the original data.
In comparison to encryption, it is more secure.	In comparison to hashing, it is less secure.
The goal of hashing is to index and retrieve data from a database. The procedure is really quick.	Encryption transforms data in order to keep it hidden from others.
The hashed data is usually short and constant in length. It does not increase in size as the length of information increases.	The length of the encrypted data is not defined. It expands as the amount of data grows longer.
Eg:- SHA256 algorithm	Eg:- RSA, AES algorithm
