The exact commands for generating a self-signed SSL certificate on Linux is something I always forget, so here they are:<\/p>\n

Generating a private key<\/h3>\n

First you need to generate a private key. This private key\u00a0will be the only key that can decrypt your SSL traffic.<\/p>\n

$ openssl genrsa -des3 -passout pass:x -out server.pass.key 2048\r\n$ openssl rsa -passin pass:x -in server.pass.key -out server.key\r\n$ rm server.pass.key<\/code><\/pre>\n
Generating a CSR (Certificate Signing Request)<\/h3>\n
Using the private key you’ve generated seconds ago, you must\u00a0now create a CSR (Certificate Signing Request). In most cases you can just use the default values for everything except the common name. The common name is usually the domain of your website.<\/p>\n
$ openssl req -new -key server.key -out server.csr<\/code><\/pre>\n
Signing the certificate<\/h3>\n
Normally you would pass the CSR to a CA (Certificate Authority) who would sign it for you. But using the following command\u00a0you\u00a0sign the certificate yourself.<\/p>\n
$ openssl x509 -req -days 365 -in server.csr -signkey server.key -out server.crt<\/code><\/pre>\n","protected":false},"excerpt":{"rendered":"
