217 * The file scheme decoders
218 * ------------------------
220 * Each possible data type has its own decoder, which either operates
221 * through a given PEM name, or attempts to decode to see if the blob
222 * it's given is decodable for its data type. The assumption is that
223 * only the correct data type will match the content.
227 * The try_decode function is called to check if the blob of data can
228 * be used by this handler, and if it can, decodes it into a supported
229 * OpenSSL type and returns a OSSL_STORE_INFO with the decoded data.
231 * pem_name: If this blob comes from a PEM file, this holds
232 * the PEM name. If it comes from another type of
233 * file, this is NULL.
234 * pem_header: If this blob comes from a PEM file, this holds
235 * the PEM headers. If it comes from another type of
236 * file, this is NULL.
237 * blob: The blob of data to match with what this handler
239 * len: The length of the blob.
240 * handler_ctx: For a handler marked repeatable, this pointer can
241 * be used to create a context for the handler. IT IS
242 * THE HANDLER'S RESPONSIBILITY TO CREATE AND DESTROY
243 * THIS CONTEXT APPROPRIATELY, i.e. create on first call
244 * and destroy when about to return NULL.
245 * matchcount: A pointer to an int to count matches for this data.
246 * Usually becomes 0 (no match) or 1 (match!), but may
247 * be higher in the (unlikely) event that the data matches
248 * more than one possibility. The int will always be
249 * zero when the function is called.
250 * ui_method: Application UI method for getting a password, pin
251 * or any other interactive data.
252 * ui_data: Application data to be passed to ui_method when
254 * libctx: The library context to be used if applicable
