1) Encryption suite interaction;2) password Exchange;3) identity authentication;Full handshakeInitially, client and server "agree upon" null encryption with no MAC and null compression. This means the record they would first send would be sent as cleartext and unprotected.First message of a handshake is a ClientHello . It is the message by which the client states its intention to do some SSL. Note that the "client" is a symbolic role; It means "the party which speaks first". It so happens this i

Reprint Address: Java version AES encryption algorithm The Advanced Encryption Standard in cryptography (Advanced encryption Standard,aes), also known as Rijndael encryption, is a block encryption standard used by the U.S. federal government. This standard, which replaces the original DES, has been analyzed and widely used worldwide. After five years of selection process, the Advanced Encryption Standard was issued by the National Institute of Standards and Technology (NIST) on November 26, 2001

the object is instantiated.We know that the reliability of fingerprint identification is very important, we certainly do not want the certification process to be a third party in some form of attack, because we introduced fingerprint authentication to improve security. However, from a theoretical point of view, the process of fingerprint authentication is likely to be malicious attacks by Third-party middleware, the common means of attack is to intercept and tamper with the results of the finge
