    ENGINE_pkey_asn1_find_str(): don't assume an engine implements ASN1 method
    Just because an engine implements algorithm methods, that doesn't mean
    it also implements the ASN1 method.  Therefore, be careful when looking
    for an ASN1 method among all engines, don't try to use one that doesn't
