      Nice guide to post-quantum cryptography.https://blog.trailofbits.com/2018/10/22/a-guide-to-post-quantum-cryptography/ …

      Nice and misleading? Table 1 claims plain elliptic curve crypto is post-quantum, even though the text points out (parenthetically) that this is not the case.

      Also implies there are no isogeny-based signatures? There totally are, even if they aren't competitive. https://eprint.iacr.org/2016/1154.pdf  https://eprint.iacr.org/2017/186.pdf

      Take a screen capture, then. Otherwise someone will silently change the text again and then claim no such assertion was ever there (rather than, say, simply admitting the glitch, thanking you, and declaring it fixed).

      This is the updated version. Before I complained, the caption simply said all schemes were post-quantum.

      I suggested a screen capture of whatever claim seems weird or out of place. If there's a claim that no signatures are possible, take a picture of it.

      The text above the table includes "isogeny-based signatures are theoretically possible but none were submitted to NIST", which is misleading: they exist, but were not submitted. The table doubles down with a big ❌ in the corresponding cell.

      Anyway, there's some good bits in there, hopefully they @trailofbits can correct these parts

      Thanks for the comments all of you. As you mentioned earlier, the body copy has correct information (and always did) and provides essential context for the table. Taken out of context, you're correct that the table could have been labelled better so we adjusted the caption.
