RFC 8032, "Edwards-Curve Digital Signature Algorithm (EdDSA)", January 2017

Source of RFC: IRTF

Errata ID: 5930
Status: Verified

Section 6 says:

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")

Notes:

Missing raise before Exception

Section 5.1.7 says:

Decode the first half as a point R, and the second half as an integer S,
in the range 0 <= s < L.

It should say:

Decode the first half as a point R, and the second half as an integer S,
in the range 0 <= S < L.

Notes:

original document expression is ' 0 <= s < L', but it must be '0 <= S < L'. upper/lower case problem.

Section 8.7 says:

   As an API consideration, this means that any Initialize Update
   Finalize (IFU) verification interface is prone to misuse.

It should say:

   As an API consideration, this means that any Initialize Update
   Finalize (IUF) verification interface is prone to misuse.

Notes:

Typo in acronym.

Section 3.1 says:

3.1.  Encoding

   An integer 0 < S < L - 1 is encoded in little-endian form as a b-bit
   string ENC(S).

It should say:

3.1.  Encoding

   An integer 0 <= S <= L - 1 is encoded in little-endian form as a b-bit
   string ENC(S).

Notes:

The range of the scalar should include the end-points: 0 and L-1.

Section 5.1.7 says:

       Decode the first half as a
       point R, and the second half as an integer S, in the range
       0 <= s < L.  Decode the public key A as point A'.  If any of the
       decodings fail (including S being out of range), the signature is
       invalid.

   2.  Compute SHA512(dom2(F, C) || R || A || PH(M)), and interpret the
       64-octet digest as a little-endian integer k.

   3.  Check the group equation [8][S]B = [8]R + [8][k]A'.  It's
       sufficient, but not required, to instead check [S]B = R + [k]A'.

It should say:

       Decode the first half R as a
       point R', and the second half as an integer S, in the range
       0 <= S < L.  Decode the public key A as point A'.  If any of the

       sufficient, but not required, to instead check [S]B = R' + [k]A'.

Notes:

1) public key R' and its encoding R are confused
2) s changed to S (this errata has been reported already)

Section 3.4 says:

Compute h = H(ENC(R) || ENC(A) || M), and check the group
equation [2^c * S] B = 2^c * R + [2^c * h] A in E.

It should say:

Compute h = H(ENC(R) || ENC(A) || M), and check the group
equation [2^c * S] B = [2^c] R + [2^c * h] A in E.

Notes:

Section 2 uses a separate notation, [n]X, for point multiplication, so this operation should use the brackets.
