WebWhen a browser connects with an export cipher, the server sends its Global ID certificate. The browser verifies this, and can then upgrade its cipher suite before any HTTP communication takes place. The problem lies in allowing browsers to upgrade in this fashion, but still requiring strong encryption. WebCiphers, also called encryption algorithms, are systems for encrypting and decrypting data. A cipher converts the original message, called plaintext, into ciphertext using a key to determine how it is done. Ciphers are generally categorized according to how they work and by how their key is used for encryption and decryption. Block ciphers ...
