[Feature] Add Encrypt - Decrypt Calculator

[bhumii-ka]

Description

This calculator will have two parts:

• Encryptor : This will take user input for a text and then give the user the encrypted text with a key.
• Decryptor : When an encrypted text (from the encryptor of the same calculator) with the key is inserted in it, it will provide the user the decrypted text.

Will this also decrypt if I put someone else's encrypted key?

If the key is different then it would show some decrypted text but that text won't be same as the original text which was encrypted.

That's a privacy concern. Give some solutions. Also this may give wrong decryption to someone whose encrypted key it actually is

Ok so I'll make it as if the key is wrong then it would show an error message " wrong key inserted" and then only decrypt the text if right key is inserted

Okay But what about the privacy concerns?
