openssl self signed certificate

certificate can be obtained from other cas or self-Signed root certificates. Here we generate a self-Signed root certificate. First, we need to add some information to the configuration file, as shown below. The section name is the same as the command req of the command line tool. We write all the necessary informatio

Background introductionIn a production environment, it is sometimes necessary to use self-signed certificates, and Google Chrome has lowered the SHA1 algorithm level since 2016, and OpenSSL uses the SHA1 algorithm, which describes how OpenSSL uses SHA256 encryption algorithms to encrypt Web sites. The topology diagram is as follows:650) this.width=650; "src="/e/u

Create a server private key, and the command will let you enter a password: $ OpenSSL genrsa-des3-out server.key 1024 Create a certificate (CSR) for the signing request: $ OpenSSL req-new-key server.key-out SERVER.CSR Remove the required password when loading SSL-supported Nginx and using the above private key: $ CP Server.key

a database) that stores private keys and verifies the corresponding public keys associated with them ).Keytool is a valid security key and certificate management tool. It enables users to use digital signatures to manage their own private/public key pairs, manage certificates used for self-identification, and manage data integrity and authentication services. It also enables users to cache their public keys during communication.A
