Quick question (can’t find in the archives whether that was discussed):

I this YANG-JSON valid for a `binary`?

"base64encodedvalue==“

Section 6.6 of RFC 7951 points to Section 9.8 of RFC 7950, which points to 
Section 4 of RFC 4648.  That says:

   When fewer than 24 input
   bits are available in an input group, bits with value zero are added
   (on the right) to form an integral number of 6-bit groups.

I read that as saying the `binary` should be encoded as:

"base64encodedvaluQ==“

(Q = 010000, e = 011110, only the first two bits are used after “u” has 
supplied six of eight for the last byte, so the rest must be zero.)

For those who don’t breathe base64, here’s the problem:

a = Base64.decode64("base64encodedvalue==").hexs
=> "6d ab 1e eb 87 a7 72 87 5e 76 f6 a5 b9”

But some bits were *not* zero in the discarded part, so we get:

Base64.encode64(a.xeh) => "base64encodedvaluQ==\n”

Of course, a strict base64classic decoder is not going to accept 
"base64encodedvalue==“ in the first place, because the sentence cited above is 
violated.
