How to create certificates on an XCOM partner server using the same root certificate. These directions use the sample certificates and make files we provide. There are directions on how to move the root certificates from platform to platform
Once you have created the root certificate on your machine, you can create certificates using that root for your partners. The files required for the root certificate are cassl.pem and casslkey.pem.
NOTE: You need to repeat this procedure for every partner that will be sending and receiving encrypted transfers.
Special Considerations when Transferring the Root Certificate
The end of line sequence is different on Windows than on UNIX and Linux.
If the partners are UNIX or Linux and z/OS then create the cassl.pem and casslkey.pem files first on UNIX or Linux. This way you can transfer them from UNIX or Linux in ASCII mode. The files are in text mode and they will transfer successfully
If the partners are Windows and z/OS and you create the certificates initially on Windows you will then need to do the following:
NOTE: This is required because the Windows certificates have an end of line sequence which is a carriage return, linefeed (x0D x0A). With Unix or Linux there is an end of line character which is linefeed (x0A). So, before you send the certificates to z/OS you need to use some utility that will convert the linefeeds to carriage return line feeds. In the example above, it is the Windows Wordpad Utility.
