This is a meta issue to keep track of asymmetric key types supported by OpenSSL and node. The following list includes all key types supported by OpenSSL 1.1.1b. Checked items are fully supported by node's KeyObject API:

The next step is to determine which of the above key types need to be dealt with in which way. Some of these types do not represent actual asymmetric keys (e.g., EVP_PKEY_SCRYPT) and thus don't need to be dealt with in the KeyObject API:

  • EVP_PKEY_SCRYPT: KDF
  • EVP_PKEY_HMAC: MAC
  • EVP_PKEY_CMAC: MAC
  • EVP_PKEY_HKDF: KDF
  • EVP_PKEY_POLY1305: MAC
  • EVP_PKEY_SIPHASH: MAC / PRF
  • EVP_PKEY_TLS1_PRF: PRF

    @tniessen ... is this still relevant? Should it remain open?

    @jasnell I think so, yes. Please leave it open for now.

    @tniessen ... just an update... I've got CMAC support on my todo list (revisiting the work that bnoordhuis had started but hadn't completed). I've also got poly1305 and siphash on my list but it'll be a while before I get to those.

    On the key types, I'm really not convinced yet that the remaining key types are a priority.
