First, you need to understand some basic concepts before installing 1. Certificates used by SSL can be self-generated or signed by a commercial ca such as Verisign or thawte. 2. Certificate concept: First, you must have a root certificate, and then use the root certificate to issue the server certificate and custom

1. After OpenSSL is installed, find OpenSSL. CnF in the/usr/lib/SSL directory (for Ubuntu system, use whereis to check the SSL directory) and copy it to the working directory. 2. Create a New democafolder under the Work directory, create the new files index.txt and serial in the folder, and then

Preface openSSL is a powerful encryption tool. many of us are already using openSSL to create RSA private key or certificate signature requests. However, you can use openSSL to test the computer. speed? You can also use it to encrypt files or messages.

Use OpenSSL to generate a certificate Step 1. Create key (password protected) Openssl genrsa-out prvtkey. pem 1024/2038 (with out password protected) Openssl genrsa-des3-out prvtkey. pem1024/2048 (password protected) The command generates a 1024/2048-bit key. Step 2.

need to add this certificate to the keychain, of course you can double-click the Aps_development.cer file and you will find it associated with the private key.To create a PEM file to your current location, you have three files:CSR filePUSHCHATKEY.P12 private Key FileSSL Certificate (Aps_development.cer)Save these three files well. You can throw the CSR away, but
