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

Turn from: HTTPS Unidirectional authentication Instructions _ digital certificate, digital signature, SSL (TLS), SASLBecause TLS + SASL is used in the project to do the security authentication layer. So read some online information, here to do a summary.1. First recommend several articles:Digital certificate: http://ww

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

csdecrypt = new CryptoStream (Msdecrypt,New TripleDESCryptoServiceProvider ().

Encryption and decryption use the same key algorithm, called symmetric encryption algorithm. encryption and decryption use different keys, called asymmetric encryption algorithms. The public key system is an asymmetric encryption algorithm. For symmetric encryption, symmetric keys must be protected. For public key algorithms, private keys must be protected.Public key encryption algorithms and derived digital signatures and

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
