Then use a non-Diffie-Hellman (DH) password, or use other sources, such as performance_schema and slow query log. it depends on which application supports the password, it may also contain some server load balancer settings. What is the difference between SSL in MySQL and SSL in browsers? The browser has a CA trust list by default, but MySQL does not. This is their biggest difference. MySQL

follows: B=gy MoD n (5) Bob sends B to Alice (6) to calculate the secret key K1 as follows: K1=BX mod n (7) calculates secret key K2 as follows: K2=ay mod nk1=k2, so Alice and Bob can use it for encryption and decryption The RSA encryption algorithm is based on the mathematical fact that two large primes are easy to multiply, while it is difficult to obtain a factor for the resulting product. The encryption process is as follows: (

layer protocol will be encrypted, thus guaranteeing the privacy of the communication.As described above, the SSL protocol provides a secure channel with the following three features:1. Confidentiality of dataInformation encryption is to convert the plaintext input file into an encrypted file using an encryption algorithm to achieve the confidentiality of the data.

When Bio_reset calls, the Ssl_shutdown function is invoked to close all currently connected SSL , and then call Bio_reset on the next bio, which typically disconnects the underlying transport connection.

When the client performs an SSL connection, JSSE determines whether to trust the server certificate based on the Certificate in this file. In SunJSSE, a trust manager class determines whether to trust a remote certificate. This class has the following processing rules:

to the specific situation in China, we can predict that the development trend of E-commerce security measures in China will be the coexistence of SET and SSL, with complementary advantages. That is, the SET protocol is used between sellers and banks, while the SSL protocol is still used when connecting with customers. This solution avoids installing software on the customer's machine. At the same time, you
