Hi,

I’d like to ask about the reasoning behind the choice of base64url as the encoding format for binary data.

I am working on the I-D

http://tools.ietf.org/html/draft-ietf-netmod-yang-json-00

which defines JSON encoding for data modelled with the YANG language [RFC6020]. Such data are primarily intended to be used in remote configuration protocols such as NETCONF or RESTCONF, so it seems to be a good use case for I-JSON and we would certainly like to comply with I-JSON rules.

However, YANG has the data type “binary” which requires base64 encoding. So I wonder - is there any reason for preferring base64url over base64? We most likely don’t need the encoded data to be URL-safe.

Thanks, Lada
