Hi folks,

 

In contrast to RFC 5280,  X.509 does not require DER encoding. It only
requires that the signature is generated across a DER encoded certificate,
but the itself certificate may be encoded using BER.

 

Should we add a sentence somewhere in X.509 and possibly in RFC 5280
specifying that when verifying a signature a relying party shall decode and
then encode the certificate in DER to verifying the signature?
