Loading a certificate from a PEM file

Examples of how to load X.509 certificates from PEM files or FGLPROFILE entries in Genero.

Loading a certificate from a PEM file

IMPORT xml

MAIN
  DEFINE x509 xml.CryptoX509
  LET x509 = xml.CryptoX509.Create()
  TRY
  CALL x509.loadPEM("certificate.crt");
    DISPLAY "Id : ",x509.getIdentifier()
  CATCH
    DISPLAY "Unable to load certificate :",status
  END TRY
END MAIN

Note:

All certificates in PEM format were created with the OpenSSL tool.

Loading a certificate from an FGLPROFILE entry

You can also load a PEM certificate by reference using an FGLPROFILE entry instead of a direct file path. This allows you to manage certificate file locations centrally in your application configuration.

Example FGLPROFILE entry:

# fglprofile
xml.myCert.cert = "/opt/local/certificate.crt"

Example code:


IMPORT xml

MAIN
  DEFINE x509 xml.CryptoX509
  LET x509 = xml.CryptoX509.Create()
  TRY
  CALL x509.loadPEM("myCert") -- loads the certificate file referenced by the FGLPROFILE entry
    DISPLAY "Id : ",x509.getIdentifier()
  CATCH
    DISPLAY "Unable to load certificate :",status
  END TRY
END MAIN

Note:

The string passed to xml.CryptoX509.loadPEM is the logical certificate name as defined in the FGLPROFILE, not a file path.
