It would be so cool if viewkeys were generated along with the addresses & shown as QRcode :-)

Lots of benefits - from showing users how they can monitor a paperwallet without losing security, apps can scan QRcode viewkeys to join services, lots of good stuff.

I downloaded the app from [this link]
debug.log
(https://github.com/ZcashFoundation/zecwallet/releases/download/v0.9.17/Zecwallet.Fullnode-0.9.17-win.zip), and it threw me the following message upon its the very first start:

Failed to start zcashd. Giving up! Please look at the debug.log file.
C:\Users\sengl_000\AppData\Roaming\Zcash/debug.log
Please file an issue with Zecwallet

Attached you may find the corresponding log file.

Hi,

I'm trying to compile zec paper wallet from code but it's keep giving me error for aes dependency. I checked on https://crates.io/crates/aes/versions which shows the specific version of aes which is used at git hash of librustzcash dependency got deleted about 3 years ago.

I'm not a rust native programmer. Can you please help fix this issue?
Would very much appreciate your help on it.

Thanks
Satinder

Her the log trying to compile zecpaperwallet as of current state:

On line 65 and line 74 of paper.rs, the zviewkey_prefix parameter values are reversed for testnet and mainnet:

if is_testnet {
        CoinParams {
            taddress_version : [0x1D, 0x25],
            tsecret_prefix   : [0xEF],
            zaddress_prefix  : "ztestsapling".to_string(),
            zsecret_prefix   : "secret-extended-key-test".to_string(),
            zviewkey_prefix  : "zviews".to_string(),
            cointype         : 1
        }
    } else {
        CoinParams {
            taddress_version : [0x1C, 0xB8],
            tsecret_prefix   : [0x80],
            zaddress_prefix  : "zs".to_string(),
            zsecret_prefix   : "secret-extended-key-main".to_string(),
            zviewkey_prefix  : "zviewtestsapling".to_string(),
            cointype         : 133
        }
    }

I have confirmed this with Section 5.6.7 of the Zcash protocol PDF:

For incoming viewing keys on the production network, the Human-Readable Part is “zviews”. For incoming viewing keys on the test network, the Human-Readable Part is “zviewtestsapling”.
