Remove include/internal/decoder.h, as it's superfluous

2023-08-15T13:23:16Z

The routines declared in there are entirely libcrypto internal, so include/crypto/decoder.h is better suited for them. Reviewed-by: Matt Caswell Reviewed-by: Hugo Landau Reviewed-by: Dmitry Belyavskiy (Merged from https://github.com/openssl/openssl/pull/21733)

Optimise PKEY decoders

2023-07-16T22:12:06Z

The most expensive part of using a PKEY decoder is the OSSL_DECODER_CTX_new_for_pkey() call. This builds up all of the decoder chains, which is a complex and time consuming operation. However, if no new providers have been loaded/unloaded since the last time it was called we can expect the same results for the same parameters. Note that this operation takes place *before* we event parse the data for decoding so it is not dependent on the parsed data at all. We introduce a cache for OSSL_DECODER_CTX objects. If we have been called with the same parameters then we just duplicate an existing OSSL_DECODER_CTX. This should be significantly faster than creating a new one every time.

Remove the _fetch_by_number functions

2022-05-06T00:38:55Z

These functions are unused and untested. They are also implemented rather inefficiently. If we ever needed them in the future, they'd almost surely need to be rewritten more efficiently.

Add method store cache flush and method removal to non-EVP operations

2022-05-05T13:06:12Z

evp_method_store_flush() and evp_method_store_remove_all_provided() only cover EVP operations, but not encoders, decoders and store loaders. This adds corresponding methods for those as well. Without this, their method stores are never cleaned up when the corresponding providers are deactivated or otherwise modified.

Refactor OSSL_DECODER_do_all_provided() to behave like OSSL_DECODER_fetch()

2021-06-15T14:21:31Z

This is refactored to use inner_ossl_decoder_fetch() without any given name, which is just there to ensure all decoder implementations are made into methods, and then use ossl_method_store_do_all() to list them all. This also adds the internal ossl_decoder_do_all_prefetched(), which can be used if pre-fetching needs to be done separately from listing all the decoder implementations, or if listing may happen multiple times.

CORE: Add an algorithm_description field to OSSL_ALGORITHM

2021-04-02T06:52:37Z

This corresponds to the |info| field in EVP_PKEY_ASN1_METHOD, as well as the generic use of OBJ_nid2ln() as a one line description. We also add the base functionality to make use of this field. Fixes #14514 Reviewed-by: Tomas Mraz (Merged from https://github.com/openssl/openssl/pull/14656)
