It is mainly used for outputting certificate information , can also sign certificate request file, self-signed, convert certificate format , etc.The OpenSSL x509 tool does not use the settings in the OpenSSL configuration file, bu

Self-signed certificates are used in a wide range of applications, such as testing, development, local or cloud Web sites (such as Microsoft Azure Web site). This article describes a method for quickly generating a self-signed certificate using PowerShell on Win8.1 and Win2012 R2, automatically exporting the private key, and automatically installing it under Loca

Self-signed certificates are widely used for testing, development, and use on local or cloud websites (such as Microsoft Azure Web Site.

After you enable Apache Mod_ssl, you need a certificate to function properly. Wrote a script to manipulate it. The first thing to make sure is that there are OpenSSL on the machine. Copy Code code as follows: #!/bin/sh # # The root directory for SSL certificate output.ssloutputroot= "/etc/apache_ssl"If [$#-eq 1]; ThenSsloutputroot=$1Fiif [!-D ${ss

First to generate the server-side private key (key file): The code is as follows Copy Code OpenSSL genrsa-des3-out Server.key 1024 The runtime prompts for a password, which is used to encrypt the key file (parameter DES3 is the encryption algorithm, of course, you can choose the other algorithm you think is safe). You need to enter a password whenever you need to read this file (the commands or APIs provided b
