Encryption is a process which transforms the original information into an unrecognizable form. Decryption is a process of converting encoded/encrypted data in a form that is readable and understood by a human or a computer.

What is encryption and decryption with example?

Decryption is the process of converting ciphertext back to plaintext. ... To decrypt a particular piece of ciphertext, the key that was used to encrypt the data must be used.
