Can't authorize on Win7 E_AUTH_INVALID_KEY_DATA bad padding

[r2p2]

If I want to authorize my Digital Editions program on my Windows 7 32bit. If I enter my credentials I geht the

error message you see in the subject.

Tried it over several days.

I'm afraid I don't think this suggestion will work in your case, but probably worth a try anyway ...

Sometimes ADE gets its registration/activation confused and in a semi-authorized state.

Unfortunately, it often then gives misleading error messages about what is wrong.

Try completely removing any authorization using ctrl-shift-D to ADE (cmd-shift-D if on Mac).

Restart ADE, and then reauthorize with your Adobe ID.

It sounds plausible, but sadly didn't help. Nevertheless thank you for the try.

I'm having the same problem.

ETA: Try using ADE 1.7 (you can find it here). It worked for me.

Preface: I know this thread is old, but I'm replying here because it's the #1 Google hit for the error.

I was receiving this error across multiple devices AND accounts. The common thread turned out to be my very long passwords (I use keychain software instead of trying to remember/type them manually.) Once I reduced my password from my usual 100 chars to a more manageable 12, the issue cleared up immediately and I was able to log in.

Length of the password turned out to be the issues on my side as well. Thanks for sharing as it solved my problem.

This was the issue for me as well. My ~100 character long password failed, and when I changed my password to a much shorter one, it worked perfectly.

How odd that you must sacrifice security for this product.

Same here, got the E_AUTH_INVALID_KEY_DATA  error when logging in from my macbook. Resetting the password to 12 chars it just worked.

Thanks!

Hey Adobe, why is this still an issue? Seriously since 2013 people have to sacrifice security to use this product! It's 2020 now and I faced this issue just now.

The solution was to have a shorter password, that shouldn't be a solution!

Unbelievable. It's been a long time since I had to use software as low quality as ADE. Just incredible.
