What is the main difference between hashing and encryption as shown in the image?
Hashing and encryption both produce a human-readable output.
Hashing is reversible while encryption is not.
Hashing produces a fixed-size hash value, whereas encryption produces an encrypted value that can be of variable length.
Encryption uses a key for the transformation process, while hashing does not.
What is the main difference between hashing and encryption techniques?
Hashing is a two-way process, while encryption is not.
Encryption is a one-way process, while hashing is not.
Hashing is a one-way process, while encryption is a two-way process.
There is no difference; both are two-way processes.
