To ensure the transmission security of online digital information, in addition to using stronger encryption algorithms and other measures in communication transmission, a trust and trust verification mechanism must be established, that is to say, all parties involved in e-commerce must have a verifiable identity, which is a digital certificate. Digital Certificates are the identity certificates used by en

), through the hashing algorithm, transformed into a fixed-length output, the output is the hash value. This conversion is a compression map, that is, the space of the hash value is usually much smaller than the input space, the different inputs may be hashed to the same output, but not from the hash value to uniquely determine the input value. Simply, a function that compresses messages of any length to a message digest of a fixed length. Common algorithms? SHA-1, SHA-256 , MD5, MD2Characteris

But then there is a problem, is how the
With the rapid development of e-commerce, information security has become one of the key issues, especially the requirements of online payment and online banking for information security. In order to carry out secure e-commerce activities on the Internet, public key infrastructure (PKI) has been widely used at home and abroad. Do we really need PKI? What is the use of P

With the rapid development of network technology, Internet has become an indispensable part of people's lives, but it also faces installation problems. To ensure that the Internet can transmit data securely, technicians have developed PKI technology.
Now let's look at the data signature for PKI.

Microsoft PKI has made many improvements in Windows Server 2008 and has added many features, the first of which is certificate lifecycle management, especially with regard to automatic registration of computers and user certificates. In Windows Server 2008, Certificate Lifecycle Management is enhanced by the use of certificate roaming new features. We will describe this feature later.
A more general practice for developers is to link the
Cryptographic algorithm encryption based on PKI)
A single-key cryptographic algorithm, also known as symmetric cryptographic algorithms, refers to encryption.KeyThe same password algorithm as the decryption key. Therefore, when transmitting and processing information, the sender and receiver of information must jointly hold this password, which is called a symmetric password ). In symmetric key cryptography algorithms, encryption and decryption operat

Digital Certificate Based on PKI
Digital Certificates are the identity certificates for various entities (cardholders/individuals, merchants/enterprises, gateways/banks) to exchange information and conduct business activities online, all parties to the transaction need to verify the validity of the certificate of the other party, so as to solve the mutual trust problem. A certificate is a digital signature provided by the certificate authority.KeyThe
