comodo digital certificate

: Digital Certificate: The name of a file, like the signature of an institution or person, that proves the authenticity of the institution or person. The information contained therein is used to implement the above functions. Encryption and authentication: encryption refers to the communication between the two parties in order to prevent most grateful information on the channel by the thi

succeeds, it proves that Alice's private key is correct and thus completes Alice's identification. The authentication process is as follows: Alice uses her private key to encrypt the file and sign the file.Alice transfers the signed file to Bob.Bob decrypts the file with Alice's public key to verify the signature.Alice uses her own private key for encryption, and Bob uses Alice's public key for decryption. Root Certificate The root

Bob, bob uses Alice's public key to decrypt the file. If the decryption succeeds, it proves that Alice's private key is correct and thus completes Alice's identity authentication. The authentication process is as follows: Alice uses her private key to encrypt the file and sign the file. Alice transfers the signed file to Bob. Bob decrypts the file with Alice's public key to verify the signature. Alice uses her own private key for encryption, and Bob uses Alice's public key f

Code is known and verified, and the Code has not been changed since the self-signature. In the first case, trust an application without any damage and trust the source of the application. In the second case, use a digital signature to verify the authenticity. Digital signatures are industrial standards used to identify and provide detailed information about code senders. The technology is based on standard

fill the basic information of the digital certificate, I will be a summary of the following. Keys and certificates: (see:http://www.microsoft.com/china/technet/security/guidance/secmod39.mspx) Asymmetric encryption uses a public/dead key pair. Data that is encrypted with the private key can only be decrypted using the corresponding public key, and vice versa. As the name suggests, a public key is a key t

1.1 concepts and functions of digital certificates A digital certificate, also known as a digital identity, is a series of data that marks the identity information of network users. It provides an identity authentication method on the Internet, which is used to mark and prove the identity of both parties in the network

HTTPS access to a Web site, server-side and client data transmission is encrypted, will not be intercepted, than the normal HTTP protocol more secure. Let me introduce the configuration of SSL under IIS6.0 to achieve HTTPS access. Detailed process screenshots are described. 1, enter the site properties, select Directory Security, and then click on the server certificate to configure the certificate:

Digital Certificates are a series of data that mark the identity information of all parties in Internet communications. They provide a way to verify your identity on the Internet, its function is similar to the driver's driving license or ID card in daily life. It is issued by an authority-Ca, also known as the certificate authorit y center. People can use it online to identify each other. A

random numbers, so clear text can not take 128 bytes full, the actual test, clear text up to 117 bytes, leaving space to fill the random number.So, using the same key to encrypt the same string of strings, each time you get the ciphertext is not the same.4. Decryption operationTo load a certificate from a certificate file, if you have a private key, you need to provide the password you set when saving the

Ask the php to read the digital certificate. now our company takes over a public security project and asks the police to log on to the system using the digital certificate, how can php read the contents of the digital certificate?

about the browser to verify the Web site digital certificate process the information on the web is generally not very clear. After consulting a lot of information finally to find out this part. Certificates issued to the site under the CA is a certificate chain, that is, a layer of certificates, starting from the root certifi
