Translation Results Requested Through Conyac Made Public

In fact, appropriate cryptography mechanism
(including encryption and decryption) should keep the cipher text safe even if
the enemy knows what algorithm which it using.
For a good encryption, the secret of the key should be sufficient
to protect the confidentiality of the data.

(Wikipedia: cryptography / cryptography and the history of crypt analysis / modern cryptography)

From the protection algorithm (encryption method)
to the new developing algorithm which makes the enemy can not decode of the cipher text, even the new algorithm is open to the public,
cryptography formally entered the dynasty of modern cryptography from the classical cryptography dynasty.

What is the modern cryptography? Let's left it for the next!
