1216 | * It takes the following arguments: | |
1217 | * | |
1218 | * impl This is the key type name that's being implemented. | |
1219 | * type This is the type name for the set of functions that implement | |
1220 | * the key type. For example, ed25519, ed448, x25519 and x448 | |
1221 | * are all implemented with the exact same set of functions. | |
1222 | * evp_type The corresponding EVP_PKEY_xxx type macro for each key. | |
1223 | * Necessary because we currently use EVP_PKEY with legacy | |
1224 | * native keys internally. This will need to be refactored | |
1225 | * when that legacy support goes away. | |
1226 | * kind What kind of support to implement. These translate into | |
1227 | * the DO_##kind macros above. | |
1228 | * output The output type to implement. may be der or pem. | |
1229 | * | |
1230 | * The resulting OSSL_DISPATCH array gets the following name (expressed in | |
1231 | * C preprocessor terms) from those arguments: | |
