Quoting your original e-mail: "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 [email protected] 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) <[email protected]>" gpg: Fatal: zlib inflate problem: invalid code lengths set The file has a size of 68 KB, could that be the culprit ?" Now addressing what I think is the culprit: You encrypt your e-mail with the public key of the recipient. When you are the recipient of an encrypted e-mail, the sender needs your publick key to be able to encrypt the e-mail that will be send to you. You, the recipient, will use your private key to decrypt this e-mail. That having been said, as far as I know, you need to configure your e-mail client (TB/Enigmail, Mutt ...) to do that for you . In otherwords, the encrypted stuff should not be pasted into the file "nachricht.txt". -- John Doe _______________________________________________ Gnupg-users mailing list [email protected] http://lists.gnupg.org/mailman/listinfo/gnupg-users
