From this point on, this engine must be specifically specified. To replace the internal EMBEDDED hack with something unique for the new module, functions to create application specific OSSL_STORE_INFO types were added. Furthermore, the following function had to be exported: ossl_do_blob_header() ossl_do_PVK_header() asn1_d2i_read_bio() Finally, evp_pkcs82pkey_int() has become public under a new name, EVP_PKCS82PKEY_with_libctx() Reviewed-by: Matt Caswell <matt@openssl.org> (Merged from https://github.com/openssl/openssl/pull/12587)
