So if we want to allow multiple b= keys, we would have to change this definition, which might
cause issues with existing libraries that were built on this invariant.
Or we could slice it the other way as I suggested a few messages back,
... s=sel1:sel2:sel3 a=alg1:alg2:alg3 b=hash1:hash2:hash3 ...
When programming, it is always preferable to define structures rather than
using coordinated arrays.
If we go with my proposal to allow a single selector to have multiple keys
with different algorithms, we could simplify it to
... s=sel a=alg1:alg2:alg3 b=hash1:hash2:hash3 ...
That's a bit better, as it eliminates one array. However, what about:
... s=sel; ab=alg1:hash1, alg2:hash2, alg3:hash3 ...?
Best
