Daira Emma Hopwood a95a0296ac ZIP 316, Revision 1: Change the Human-Readable Part for Revision 1 unified encodings. 
This change ensures that wallets that have not yet been updated to ZIP
316 Revision 1 will fail to recognise Unified Addresses with
MUST-understand metadata, and consequently will not violate any
restrictions imposed on transfers by those metadata items'
requirements.

This reverts commit 7064e8229a, reversing
changes made to 82f98ec91b.

Revision 1 will be amended to include a change to the Human-Readable
Part of UA/UVK encodings in order to ensure that MUST-understand
metadata cannot be ignored by existing wallets.

Kris Nuttycombe d4d34ed6ff ZIP 316, Revision 1: MUST-understand metadata items 
Reserve a range of metadata typecodes that unified container parsers
must understand; if a parser does not understand a typecode in the
specified range, then it must treat the entire unified address as
unsupported.

dk is already a byte sequence. 2023-08-22 20:30:42 +01:00
Andrew Arnott 61654491ce
Fix ZIP-316 bug in expected `dk` length 
The `dk` value is 256 bits long. It's the *diversifier* that is only 88 bits long. The incoming viewing key requires the diversifier key -- not the diversifier.

This change also reflects the de facto standard in implementations up to this point, including YWallet and the [zcash_address crate](https://docs.rs/zcash_address/latest/src/zcash_address/kind/unified/ivk.rs.html).
