/*
|
|
* MAKE_DECODER is the single driver for creating OSSL_DISPATCH tables.
|
|
* It takes the following arguments:
|
|
*
|
|
* keytype_name The implementation key type as a string.
|
|
* keytype The implementation key type. This must correspond exactly
|
|
* to our existing keymgmt keytype names... in other words,
|
|
* there must exist an ossl_##keytype##_keymgmt_functions.
|
|
* type The type name for the set of functions that implement the
|
|
* decoder for the key type. This isn't necessarily the same
|
|
* as keytype. For example, the key types ed25519, ed448,
|
|
* x25519 and x448 are all handled by the same functions with
|
|
* the common type name ecx.
|
|
* kind The kind of support to implement. This translates into
|
|
* the DO_##kind macros above, to populate the keytype_desc_st
|
|
* structure.
