I’m looking for information on how to embed a logotype on a X.509 PEM certificate, for the purposes of doing some tests with BIMI, using OpenSSL to generate a CSR. I have assembled all bits and pieces I need, except figuring out how to ‘convert’ the ASN.1 definition of the logotype-embedding extension into a so-called ‘configuration file’ that the OpenSSL CLI will accept.
