ENCRYPTION

• Encryption is the conversion of electronic data into another form,

called ciphertext, which cannot be easily understood by anyone

except authorized person.

• The primary purpose of encryption is to make digital data private

and confidential.

• Normally it is done with the help of a key or an algorithm.

DECRYPTION

• Decryption is the process of transforming data that has been

rendered unreadable through encryption back to its unencrypted

form.

• In decryption, the system extracts and converts the garbled data and

transforms it to texts and images that are easily understandable by

everyone.

• Decryption may be accomplished manually or automatically. It may

also be performed with a set of keys or passwords.
