Data that can be read and understood without any special measures is called
plaintext or cleartext. The method of disguising plaintext in such a way as to
hide its substance is called encryption. Encrypting plaintext results in
unreadable gibberish called ciphertext. You use encryption to ensure that
information is hidden from anyone for whom it is not intended, even those
who can see the encrypted data. The process of reverting ciphertext to its
original plaintext is called decryption.
