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