Error: Hi bit unset in PGP packet header.

[yuangezhizao]

Hi，i use my PGP key but a error occur.

# node -v
v13.8.0
# npm -v
6.13.7

At first i export my private key like this.

C:\Users\yuangezhizao>gpg -K
C:/Users/yuangezhizao/AppData/Roaming/gnupg/pubring.kbx
-------------------------------------------------------
sec   rsa2048 2018-09-29 [SC] [expires: 2020-09-29]

C:\Users\yuangezhizao>gpg -a -o secring.gpg  --export-secret-keys CDBEC3268512836F92AA92DCED075DCBF4BFFD51

Then，i use the hs-airdrop command tools.

# ./bin/hs-airdrop ../secring.gpg CDBEC3268512836F92AA92DCED075DCBF4BFFD51 <rm> 0.01

So，how to fix it? Thanks.

@yuangezhizao can you try exporting your key in binary format, i.e. unarmored.

I got an error says Error: Unknown S2K function. after export my seckey unarmored using GnuPG2, could you help?

Edit: my exported key file is: secring.gpg: PGP Secret Key - 4096b created on Fri Apr 8 06:40:52 2016 - RSA (Encrypt or Sign) e=65537 hashed AES with 128-bit key Salted&Iterated S2K SHA-1

And cat secring.gpg | gpg --list-packets | grep S2K shows:

@yuangezhizao can you try exporting your key in binary format, i.e. unarmored.

@yuangezhizao lternatively, you can use a .asc extension on the armored file. It looks like hs-airdrop expects .gpg files to be in binary format, while armored files should have .asc extensions.

@boymanjor It works，thanks a lot！

C:\Users\yuangezhizao>gpg --armor --output secret.asc --export-secret-keys CDBEC3268512836F92AA92DCED075DCBF4BFFD51

# ./bin/hs-airdrop ../secret.asc CDBEC3268512836F92AA92DCED075DCBF4BFFD51 <rm> 0.01
I found key 0xCDBEC3268512836F92AA92DCED075DCBF4BFFD51, but it's encrypted.

This means your key was not found in the airdrop tree.
If you registered at handshake.org, use that address.
Usage: $ hs-airdrop [addr]

However, unfortunately my key was not found. :joy:
