dkim.KeyFormatError: Unparsable private key: Unexpected tag (got 30, expecting 02)

HI,

i have installed docker and everything new and doubled checked everything (DNS, FILES, Conf).
I can't register at the app because activation Mail not arriving. If i resend the activation mail, i will get Error 500 in Frontend.

So i looked at the logs from sl-app. I found something related to dkim:

dkim.KeyFormatError: Unparsable private key: Unexpected tag (got 30, expecting 02)

dkim.asn1.ASN1FormatError: Unexpected tag (got 30, expecting 02)

root@simplelogin:~# ls -l
total 20
-rw-r--r-- 1 root root  916 May 31 10:58 dkim.key
-rw-r--r-- 1 root root  272 May 31 10:58 dkim.pub.key
-rw-r--r-- 1 root root  823 May 31 10:19 simplelogin.env

whats that about? I recreated the DKIM Keys and readded, rebooted and so on but nothing, same Error.

Am i missing something?

Okay,
i had openSSL 3.x on Ubuntu 22.x
i used locally OpenSSL 1.x and now DKIM Keys where accepted. Everything is working fine.

THANK YOU.

Glad that the issue is solved 👍

So, can't we use openssl 3.X? I'm facing the same issue. am I required to use openssl 1.X?

You can use the -traditional switch like this to create a PKCS#1 key:

openssl genrsa -traditional -out privkey.pem 2048

Newer versions default to PKCS#8
