[CFRG] Proposed resolution for erratum 5930 on RFC 8032

[Alexey Melnikov <[e-mail]>]

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. So I propose to resolve 
this erratum as suggested by Daniel.

Please provide your feedback by the end of January 29th.


Best Regards,

Alexey, as a co-chair
