[Curdle] Key examples in draft-ietf-curdle-pkix-03

[str4d <[e-mail]>]

Hello,

I am currently updating my EdDSA Java library to implement the current
spec for key encoding [0] (previously I used
draft-josefsson-pkix-eddsa-04 for public keys, and the equivalent in
PKCS#8 format for private keys). The example public key given in
draft-ietf-curdle-pkix-03 [1] passes my tests, however the example
private key [2] does not.

It appears that the private key material within the example is 34 bytes,
but according to Section 3.2 of draft-irtf-cfrg-eddsa-08 [3] (which
AFAICT the present draft defers to for encoding), the private key is the
b-bit seed k, which is 32 bytes.

Am I missing something? If the example keys in the present draft are
correct, it would be helpful to add a reference that clarifies their
exact encoding.

Thanks,
Jack Grigg
