^^^ This. Future retrospective decryption of today’s intercepts. Most
people do not understand the threat model for this.
On a not unrelated note, see also, among other things, the nuanced
discussion of “The benefits-do-not-exist argument” in:
2025-01-18: “As expensive as a plane flight: Looking at some claims that
quantum computers won’t work.”
https://blog.cr.yp.to/20250118-flight.html
I do agree with Robert J. Hansen that it’s best not to (as I will put
it) casually sketch a kind of handwavy *ad hoc* cryptographic protocol
in a tangent that’s dragging this thread entirely off-topic, reducing
S/N ratio. (I will skip that part of the discussion.)
And why bother? Real Cryptographers™ have already done the hard work
for securely hybridizing the needed algorithms, and developers such as
WK and the GnuPG devs have already implemented it *a year ago* (v.2.5.1
stable/forward-compatible protocol for ECC+Kyber).
Please just use their stuff. :-)
Always,
