openssl self signed certificate

First, the HTTPS service must be built with an HTTPS certificate. This certificate can be viewed as an application-level certificate. The reason for this is that the HTTPS certificate is generated based on the CA certificate. For official websites, CA certificates require a

Web Server supports HTTPS access requiring two files, private keys, and certificates. The private key and certificate are placed on the server, the private key is used to encrypt the data, and the certificate is passed to the client. Your own signed certificate is passed to the browser, because the

create a Root CA. We can only sign the certificate request by ourselves. Therefore, we asked OpenSSL to sign the request using the key attached to the certificate request, that is, the so-called "Self sign ": $ OpenSSL ca-selfsign-In careq. pem-out cacert. pem Parameter description CA

SSL security certificates can be generated on their own or through a third-party CA (certification authority) Certification Center payment request. SSL security certificates include: 1, CA certificate, also called root certificate or intermediate level certificate. For one-way authenticated HTTPS, the CA certificate is

1. to generate a self-signed certificate, you usually need to configure an https server and an X509 certificate that is authenticated by a formal CA. When the client connects to the https server, the CA's common key is used to check whether the certificate is correct. However, it is very troublesome to obtain the CA

private key is obtained, then the key file of the private key is used to generate the sign req file (. CSR), and the CSR file is sent to the authority, awaiting certification by the authority, and the certificate file (. crt) is returned after successful authentication. A: Generate the private key key.Step A is consistent with the second section using OpenSSL to generate the RSA key pair. Use command:

1. First to generate the server-side private key (key file):Command:OpenSSL genrsa-des3-out Server.key 1024The runtime prompts for a password, which is used to encrypt the key file (the parameter des3 is the encryption algorithm, and of course you can choose other algorithms that you think are safe). You need to enter a password whenever you need to read this file (via the command or API provided by OpenSSL)2. Generate CSR and key on the serverCommand

The main file types and protocols for certificates are: PEM, DER, PFX, JKS, KDB, CER, Key, CSR, CRT, CRL, OCSP, SCEP, etc. Pem–openssl uses the PEM (privacy enhanced Mail) format to hold various information, which is the default way of storing information in OpenSSL. The PEM file in Openssl generally contains the following information: Content type: Indicates wha
