Hello, we changed ower key for pgp a while ago. Some partners now send us mails te gateway can not decrypt. We create a new key with ed25519 and import this key to the gateway. When I test sending a mail with this key I can send it via Thunderbird from private to the mail behind the gateway. But our partner see on his gateway that the message was encrypted, but the ciphermail gateway did not decrypt the message. I just receive an asc file. So to verify we also create a RSA4096 ke also with no success. When the partner changed back to 2048 everthing is fine. Is it possible to modify the log settings so I can see for what header the ciphermail gateway is looking or some other possibility to check where the problem is located. Regards Robert ---

To make sure I understand the issue, so you can send an email encrypted with ed25519 from your Thunderbird to the gateway and this email is then decrypted but, not when your partner sends the email? ---

Correct. The email from Thunderbird is working. The partner gateway is “Julia Mailoffice” and the log from them say it was encrypted correctly. I cann decrypt the received \*asc file local via gpg so the key is the correct one. ---

Maybe some usefull header from t different senders where the message isn’t decrypted when it comes with ed25519 ```auto Content-Type: multipart/encrypted; boundary=--mime6428d0b64adc0a4ee6cd2e1cd7b42916; protocol="application/pgp-encrypted" ----mime6428d0b64adc0a4ee6cd2e1cd7b42916 Content-Type: application/pgp-encrypted Version: 1.0 ----mime6428d0b64adc0a4ee6cd2e1cd7b42916 Content-Type: application/octet-stream; name=encrypted.asc ``` and the other ```auto Content-Type: multipart/encrypted; boundary=NoSpamProxy_efaed941-2aae-4e6b-a260-2c1430f86bf6; protocol="application/pgp-encrypted" Content-Language: de-DE This is an OpenPGP/MIME encrypted message (RFC 2440 and 3156) --NoSpamProxy_efaed941-2aae-4e6b-a260-2c1430f86bf6 Content-Type: application/pgp-encrypted; Content-Disposition: inline; Version: 1 --NoSpamProxy_efaed941-2aae-4e6b-a260-2c1430f86bf6 Content-Type: application/octet-stream; charset=us-ascii; name=encrypted.asc Content-Disposition: attachment; filename=encrypted.asc ``` ---

Dear Martijn, I found the solution. The ed25519 key I had generated with gpg2 had the following attributes: Enc.: AES256, AES192, AES, 3DES AEAD: OCB Digest: SHA512, SHA384, SHA256, SHA224, SHA1 Compression: ZLIB, BZIP2, ZIP, not comp Attributes: MDC, AEAD, Keyserver no-modify The problem seems to be the AEAD, after I removed the attribute, no one can use it (without manuell modification) so I can not get a message with the following info if I use gpg2 external: AES256.OCB That seems the problem. This attribute is for example also added in Outlook and the gpg Addon, if the generate key supports it. So maybe a update is possible where the AEAD attribute is supported, because anyone could add this attribute, if he modify the key or the gateway on the other hand use it. Regards Robert ---

Can you try the version from the following post? This contains some updated libraries > [@Aes128 gcm / aes128 cbc?](https://community.ciphermail.com/t/aes128-gcm-aes128-cbc/942/8): > > Hello Martijn, would it be possible to provide the GCM support in a hotfix? From 01.10. new regulations apply and Ciphermail would no longer be edi-compliant in Germany. I would appreciate a prompt reply on this topic. Many thanks in advance We have been working for the past couple of years on a major rewrite. It should be ready soon but if the above version is not working for you, you might try the new version. ---
