PATCH 1/1 crypto: xchacha - add test vector from XChaCha20 draft RFC
From: Eric Biggers <[email protected]>
There is a draft specification for XChaCha20 being worked on. Add the XChaCha20 test vector from the appendix so that we can be extra sure the kernel's implementation is compatible.
I also recomputed the ciphertext with XChaCha12 and added it there too, to keep the tests for XChaCha20 and XChaCha12 in sync.
