Re: gpg: [don't know]: 1st length byte missing

Thanks, Werner!

No backup, and I think there is no way to recover the password, which
- in this case - is very unfortunate. :( I wonder how this happened.
The drive is a Samsung EVO SSD with NTFS.

The data is corrupted.  It consists of a probably corrected public key
encrypted packet (with the encrypted session key) followed by a single
byte 0xD2 which indicates the encrypted data packet.  However this is
the last byte of the data and the length bytes as well as as the header
of the encrypted data packet is missing. 

I can't tell why this message was truncated.  Its truncated length is
512 + 16.  I hope you have a backup.



Salam-Shalom,

   Werner

See the attached file. When I try to decrypt it using `gpg -d`, I get:

IIRC I haven’t updated gpg since I encrypted the file. So I assume that
the same gpg 2.2.1 has been used for encryption.

The private key is on an OpenPGP smartcard by ZeitControl.

*Any idea how to fix the issue?*
