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.
