Created attachment 458398 [details, diff] 0001-Use-ASN1_STRING_get0_data-for-openssl-1.1.0.patch I submitted a patch for this to upstream's mailing list, but apparently it takes a while before it shows up in the list archive. I have attached a version of the patch backported to opusfile-0.8.
Seems to be fixed meanwhile.
