Creating a Self-Signed Root Certificate Authority

Create a self-signed certificate authority (CA), or use an existing one. If you use your own CA, you will need the CA certificate later.


On the Windows machine where SAP Mobile Platform is installed, download OpenSSH or another tool that supports Linux commands. Run the commands using an account for which you have Administrator privileges.


  1. In a Linux command window, run:
    “openssl genrsa -des3 -out Root_CA.key 1024”
    “openssl req -new -x509 -days 9999 -key Root_CA.key -out Root_CA.crt”
  2. Enter the values requested by openssl.

    Note the key length and verify that each system supports it.
