I note that erratum 5930 is still in the "reported" stage for RFC 8032, despite it being clearly correct. Can we move it to "Verified"? I don't much care whether it is marked as "Technical" or "Editorial". https://www.rfc-editor.org/errata_search.php?eid=5930 --dkg On Mon 2021-01-18 07:52:23 +0200, Ilari Liusvaara wrote: > On Fri, Jan 15, 2021 at 05:39:22PM +0000, Alexey Melnikov wrote: >> Dear CFRG (and editors), >> >> Daniel Bleichenbacher submitted the following editorial erratum on RFC 8032 >> ("Edwards-Curve Digital Signature Algorithm (EdDSA)") >> >> Section 6 says: >> >> OLD: >> >> def verify(public, msg, signature): >> if len(public) != 32: >> raise Exception("Bad public key length") >> if len(signature) != 64: >> Exception("Bad signature length") >> >> It should say: >> >> def verify(public, msg, signature): >> if len(public) != 32: >> raise Exception("Bad public key length") >> if len(signature) != 64: >> raise Exception("Bad signature length") >> >> >> Note: Missing raise before Exception >> >> ------------------- >> >> This is indeed looks like a Python syntax error.
