Are there any security concerns with transmitting my .BESLicenseRequest or license.crt file over the internet?
No, the license.pvk file is the only part of your key files that needs to stay private. Your .BESLicenseRequest file contains information about your deployment and licensing information. The license.crt file is your public key file and has to be combined with your private key file to complete your license. You can open the license files in a text editor to review the information contained in the files.
