There was a problem hiding this comment.
Question: what is the meaning of skeycount in this context?
There was a problem hiding this comment.
pkeycount = handler->ctx->recipients.size();
skeycount = handler->ctx->passwords.size();
These are the number of SKESK or PKESK packets.
When writing the code I assumed that only one of those variables is non-zero, meaning, we have distinct cases for symmetric and asymmetric encryption. I now think that is a wrong assumption and you can actually use PKESK and SKESK packets simultaniously for the same SEIPD message.
Thus, I will need to adapt the logic here to also take into account the v2-SEIPD capability of the "PKESK recipients".

@ni4 from my view this could be merged. Do you have any comments on the PR? |

@TJ-91 Could you please resolve conflicts here? I'm not seem able to push to this branch. Thanks! |

@ni4 I rebased (but now checks fail like on main) |

@ni4 I rebased again and all checks pass. Is it ready to merge? |

I added generating and parsing of v6 SKESK packets. They work similarly to the already implemented AEAD stuff, but use SEIPDv2 instead, and also, use HKDF for key derivation.
I added the Crypto Refresh test vectors for EAX/OCB, as well as an encrypt-decrypt test.
Further, I added the
rnp_op_encrypt_enable_skesk_v6()API call that enables creating v6 SKESK. In the CLI it can be activated with--enable-v6-skesk.The default behaviour for SKESK should be the same as before, even when compiling with
ENABLE_CRYPTO_REFRESH.
