Hi ML,

i'm new to GPG, so please excuse asking silly questions.
I managed to create my keys with "gpg2 --gen-key"
I wrote an e-Mail to adele at with the subject "Mein öffentlicher Schlüssel", which is german for "my public key".
Shortly thereafter i got an encrypted response which, i assume, i have to decrypt with my private key.
I pasted the encrypted stuff into a file and then tried to decrypt:

gpg2 -d nachricht.txt

I've been asked for the passphrase for my private key which i entered, but then i got the following error:

gpg: encrypted with 2048-bit RSA key, ID F742DB29, created 2019-07-23
      "Bernd Lentes (Helmholtz GPG Schluessel) <bernd.lentes at>"
gpg: Fatal: zlib inflate problem: invalid code lengths set

The file has a size of 68 KB, could that be the culprit ?
