The PKCS#11 provider has a mechanism [1] to support older applications which have not yet migrated to the OSSL_STORE API [2]. It works by encoding the 'pkcs11:' URI into a PEM file and passing that to an application as a file. From the application's perspective it loads the private key from a file, but OpenSSL will transparently use select the provider to access it via PKCS#11 instead. Instead of upstream's Python-based tool [3] (which would pull in asn1crypto as a dependency), we just generate the ASN.1 for the PEM using OpenSSL's 'asn1parse -genconf'. It has been tested with RAUC, U-Boot's mkimage (for signed FITs) and NXP's CST.
