WebThe key difference between encryption and hashing lies in the fact that in case of encryption, the unreadable data can be decrypted to display the original plaintext data with the help of the right key, whereas in hashing, this cannot be done at all. Encryption of data is done through the use of cryptographic keys. WebJan 5, 2024 · Not reversible – We can’t reverse a hash function back to the original password. Collision resistant – Two inputs do not result in the same output. Non-predictable – A hash function randomly generates a unique hash value that is not predictable. Compression – The hash function’s output is much smaller than the input size.
