I hope this is the correct category for my question.
I'm trying to decrypt my messages without involving the Joplin App (for a project I'm doing). When using openssl_decrypt (in PHP) I get this message "Setting of IV length for AEAD mode failed"
What am I missing to get the IV length correct? (I'm base64 decoding it before usage, as it looks base64 encoded)
Do any of you have experience with this?
@kimdk welcome to the forum.
I am not knowledgeable about Joplin encryption but I have seen the below information linked in other posts. Thought I'd mention it just in case it helps.
This page gives further information on Joplin E2EE.
Thanks for your answer.
I saw those posts, but I can't figure out why I can’t make it work.
From this git hub (dot) com/laurent22/joplin/issues/3937 (sorry for the bad link - I'm not allowed to use links) I infer that PHP is not a preferable way for decoding Joplin messages.
Then I tried in plain bash using OpenSSL, and using the "aes-128-ccm" cipher, I am getting another error saying "AEAD ciphers not supported". Using "aes-128-cbc" I get a "bad magic number" error.
Some things I definitely miss in my understanding
