Process of scrambling an electronic document using an algorithm whose key is 256 bits in length. The longer the key, the stronger it is. A Asymmetric cryptography Ciphers that imply a pair of two keys during the encryption and decryption processes. In the world of SSL and TLS, we call them...
In cryptography, a key is a string of characters used within an encryption algorithm for altering data so that it appears random. Like a physical key, it locks (encrypts) data so that only someone with the right key can unlock (decrypt) it. The original data is known as the plaintext,...
If the certificate is in the CRL, the client considers the certificate invalid. Security Mechanisms SSL provides the following security mechanisms: Connection privacy SSL uses symmetric cryptography to encrypt data. It uses the Rivest-Shamir-Adleman (RSA) algorithm (an asymmetric algorithm) to encrypt...
The RSA key exchange algorithm, while now considered not secure, was used in versions of TLS before 1.3. It goes roughly as follows: The 'client hello' message: The client initiates the handshake by sending a "hello" message to the server. The message will include which TLS version the ...
数据被哈希后产生一小串比特字符串,微小的数据改变将导致哈希串的变化。发送加密数据时,SSL 会使用加密哈希功能来确保数据一致性,用来阻止第三方破坏通讯数据完整性。SSL 常用的哈希算法有 Message Digest 5(MD5)和 Secure Hash Algorithm(SHA)。 消息认证码(Message Authentication Code):消息认证码与加密哈希功能相似...
