This command is used to convert a certificate file from one format to another using the OpenSSL utility. Here is a breakdown of the command:
openssl: It is the command to run the OpenSSL utility.x509: It specifies that we want to work with X.509 certificates.-inform ${der}: It specifies the format of the input certificate file.${der}represents the variable holding the value "der", indicating that the file is in DER format.-outform ${pem}: It specifies the format of the output certificate file.${pem}represents the variable holding the value "pem", indicating that the file should be converted to PEM format.-in ${original_certificate_file}: It specifies the path to the original certificate file that needs to be converted.${original_certificate_file}represents the variable holding the actual file path.-out ${converted_certificate_file}: It specifies the path for the converted certificate file.${converted_certificate_file}represents the variable holding the actual file path.
So, this command takes a certificate file in DER format, converts it to PEM format, and saves the converted file to the specified location.
