Exporting the certificate - References - SIMATIC AX - AX Hardware Engineering documentation - Hardware Engineering,

Run the pkcs12 command to parse the existing PKCS12 certificate and export a certificate containing public keys of it:

openssl pkcs12 -in PlcCertificate.p12 -out PlcCertificatePublic.crt -nokeys

• Explanation of the parameters provided in the command line:
  • openssl pkcs12 : the command for executing OpenSSL to parse content of a PKCS12 certificate.
  • -in PlcCertificate.p12 : the file "PlcCertificate.p12" is taken as input to read the PKCS12 certificate content from.
  • -out PlcCertificatePublic.crt : the output file "PlcCertificatePublic.crt" is generated to store the certificate content with the public key.
  • -nokeys : No private keys will be output.

• Execution of the command will cause a prompt asking for the password of the given PKCS12 certificate. This is the password which is decided in the 4th step of Generating the certificate via batch script.

• Detailed documentation about the openssl pkcs12 command can be found in the OpenSSL documentation for PKCS12 parameter.
