How Do I Convert a Certificate into PEM Format?

Only .pem certificates can be used in WAF. If the certificate is not in .pem format, convert it into .pem locally by referring to Table 1 before uploading it.
Table 1 Certificate conversion commands

Format

Conversion Method

CER/CRT

Rename the cert.crt certificate file to cert.pem.

PFX
  • Obtain a private key. For example, run the following command to convert cert.pfx into key.pem:

    openssl pkcs12 -in cert.pfx -nocerts -out key.pem -nodes

  • Obtain a certificate. For example, run the following command to convert cert.pfx into cert.pem:

    openssl pkcs12 -in cert.pfx -nokeys -out cert.pem

P7B
  1. Convert a certificate. For example, run the following command to convert cert.p7b into cert.cer:

    openssl pkcs7 -print_certs -in cert.p7b -out cert.cer

  2. Rename certificate file cert.cer to cert.pem.

DER
  • Obtain a private key. For example, run the following command to convert privatekey.der into privatekey.pem:

    openssl rsa -inform DER -outform PEM -in privatekey.der -out privatekey.pem

  • Obtain a certificate. For example, run the following command to convert cert.cer into cert.pem:

    openssl x509 -inform der -in cert.cer -out cert.pem
  • Before running an OpenSSL command, ensure that the OpenSSL tool has been installed on the local host.
  • If your local PC runs a Windows operating system, go to the command line interface (CLI) and then run the certificate conversion command.
