This page provides useful shell commands and instructions to create and manipulate certificates with ProSBC.
Installing a custom private key and local certificate on ProSBC
See WEB Portal configuration documentation
Use ProSBC (or Linux) shell to manipulate certificates
You can use ProSBC's shell (or most Linux hosts' shell as long as OpenSSL is installed) to create and view private keys, certificates and CSRs (certificate signing requests).
Create new private key
openssl genrsa -aes256 -out MY_PRIVATE_KEY.pem 2048
You will be prompted to enter a pass phrase:
Generating RSA private key, 2048 bit long modulus .....................+++ ..............................+++ e is 65537 (0x10001) Enter pass phrase for MY_PRIVATE_KEY.pem: Verifying - Enter pass phrase for MY_PRIVATE_KEY.pem:
Resulting file:
-rw-r--r-- 1 root root 1704 Mar 14 09:15 MY_PRIVATE_KEY.pem
Create a self-signed certificate from a private key
openssl req -x509 -sha256 -nodes -days 365 -newkey rsa:2048 -keyout MY_PRIVATE_KEY.pem -out MY_CERTIFICATE.crt
You will be prompted to answer questions regarding the certificate:
Generating a 2048 bit RSA private key .........................................................+++ ........................................................................................................................................................................................+++ writing new private key to 'MY_PRIVATE_KEY.pem' ----- You are about to be asked to enter information that will be incorporated into your certificate request. What you are about to enter is what is called a Distinguished Name or a DN. There are quite a few fields but you can leave some blank For some fields there will be a default value, If you enter '.', the field will be left blank. ----- Country Name (2 letter code) [XX]:CA State or Province Name (full name) []:Quebec Locality Name (eg, city) [Default City]:Boucherville Organization Name (eg, company) [Default Company Ltd]:TelcoBridges Organizational Unit Name (eg, section) []: Common Name (eg, your name or your server's hostname) []:MySBC Email Address []:support@telcobridges.com
Resulting files:
-rw-r--r-- 1 root root 1415 Mar 14 09:15 MY_CERTIFICATE.crt -rw-r--r-- 1 root root 1751 Mar 14 09:14 MY_PRIVATE_KEY.pem
Create a CSR (certificate signing request) from a private key
openssl req -key MY_PRIVATE_KEY.pem -new -out MY_CSR.csr
You will be prompted to answer questions regarding the certificate:
