Converting a certificate from PEM to DER format

Kaspersky Security Management Suite supports uploading of certificates only in DER format. You can convert a certificate file from PEM to DER format.

To carry out these instructions on the local computer, you must have the OpenSSL tool.

To convert a certificate file from PEM to DER format:

1. Start the console on the local computer.
2. Go to the folder containing the PEM certificate file and run the following file conversion command:

   openssl x509 -outform der -in <certificate file name>.pem -out <certificate file name>.der

   where:

   • <certificate file name>.pem is the original certificate file name in PEM format.
   • <certificate file name>.der is the converted certificate file name in DER format.

The new certificate file in DER format will be generated in this same folder.
