CG: n
CT: A public-key algorithm (also known as an asymmetric algorithm) is one where the keys used for encryption and decryption are different, and the decryption key cannot be calculated from the encryption key. This allows someone to keep a public-key/private-key pair.

N: 1. -asymmetric (adj): From “a-” + “symmetric”, as Ancient Greek ἀσυμμετρία (asummetría, “disproportion, deformity”).
– algorithm (n): “Arabic system of computation”; from French algorithme (under mistaken connection with Greek arithmos “number”; from Medieval Latin algorismus, a mangled transliteration of Arabic al-Khwarizmi “native of Khwarazm” (modern Khiva in Uzbekistan), surname of the mathematician whose works introduced sophisticated mathematics to the West. The earlier form in Middle English was algorism (early 13c.), from Old French.
2. An asymmetric cipher that uses two keys, one for encryption, the public key, and the other for decryption, the private key.
3. The public key can be distributed to allow others to encrypt e-mails. The private-key is not shared with anyone, and is the only way to decrypt e-mails that have been encrypted with the public-key. However, given an insecure encryption algorithm or lost private key, this system can be broken.
4. As implied by the key names, the public key used to encode plaintext can be made available to anyone. However, the private key must remain secret. Only the private key can decrypt the ciphertext.
