I asked for x448 key exchange support in 2017, and even offered to write the code for it. The devs didn't want it, citing that they'd rather add support quantum-resistant exchanges instead. Eventually we got sntrup761x25519-sha512@xxxxxxxxxxx, which provides 128-bit of symmetric security. I'd like sntrup761x448-sha512@xxxxxxxxxxx, which would provide ~256 bits of symmetric security. -- Joseph S.
