| The process of disguising ordinary text or plaintext is called encryption, and encrypted data is called ciphertext. |
| A simple pseudorandom number stream was added to the plaintext stream to create ciphertext. |
| Authenticity of the ciphertext can be established by decrypting it with your public key. |
| In the discussion of the preceding paragraphs, the cryptanalyst knows only the ciphertext and general structural information about the plaintext. |
| For a normal Internet surfer, a session online is probably about 95 percent cleartext, five percent ciphertext. |
| The process of transforming ciphertext back to plaintext is called decryption. |
