I think NBitcoin is probably ignoring the whitespace since it seems the key is valid.

Hi sir @brunoerg can I work on this one...

Oct 20 '25 14:10 Sukuna0007Abhi

@Sukuna0007Abhi There is nothing to work about it from our side. Thanks.

We need to check if the BIP mentions anything about this spaces.
