verisign digital certificate

Digital Certificate is a common content in computer security. On the network, the most common situation is probably the use of SSL secure connections. I will not introduce the digital certificate, RSA algorithm, DSA algorithm, message digest, mutual SSL, and other content. Anyone who needs it should be familiar with it

OrderThe previous article introduced several concepts related to CA certificates, which are important to understand the digital certificate and how it works. This article is mainly to analyze the CA certificate, to tell the basic composition of the certificate, which is necessary to generate a correct, accessible certi

1, we log in to pay after the treasure in the following we find the icon to use the mouse to put in the Payment Treasure home page This digital certificate, in the rebound tips we click "Management" words 2, and then the following section, we click on the word "management" 3, here will see we have installed the digital

Preface First look at Baidu Encyclopedia of Digital Signatures and digital certificate interpretation: Digital Signature: A fixed-digit message digest is computed by the hash algorithm agreed by both parties. Mathematically guaranteed: As long as any one of the changes in the message, the recalculated report digest to

correctness of Public Key + private key cannot be proved. Digital Certificate Verify the correctness of the public key in Signature A digital certificate is a file digitally signed by the certificate authorization center that contains information about the public key owner

explanation:A: The digest operation will be summarized after the digest (message Integrity), and then the digest with a private key encryption (identity authentication), to obtain a digital signature, cipher and digital signature piece to B.B: After receiving a message, the ciphertext is decrypted with its own private key, and the plaintext is obtained. After the digit
