Now that I read separate 'QUIC Crypto' page. It sounds bit of a deja vu.

QUIC also uses Curve25519 pubkey and Salsa20 cipher, which is hard to
attribute as chance, considering both are DJB's work, both are used by his
NaCl library and by extension by MinimaLT. Neither is particularly common
algorithm.

I'm not implying QUIC plagiarizes MinimaLT, there are differences in the
protocol, just choice of the algorithm implies QUIC authors are aware of
MinimaLT.
