Export feature is broken

[OlliV]

It seems that I can't export anymore. I can decrypt my old backups just fine but since I don't know when the new backups can't be decrypted anymore. This is the error I'm getting with openssl enc -d -a -aes-256-cbc -in <file>:

bad decrypt
88625:error:06065064:digital envelope routines:EVP_DecryptFinal_ex:bad decrypt:/BuildRoot/Library/Caches/com.apple.xbs/Sources/OpenSSL098/OpenSSL098-64.30.2/src/crypto/evp/evp_enc.c:330:

Maybe something is appended to the key?

I'm using Sailfish OS 2.1 and SailOTP 1.5

Probably the same issues as #14

Seems like there is some kind of problem with the encryption, I agree that this and #14 probably have a common cause. Strange thing is that I didn't change anything in the encryption code since a long time.. maybe some kind of incompatibility with new QT-Version in SFOS 2.1. I'll investigate this further as soon as I get some free time an my hands..

Just out of interest, are you seeing this on a Phone or a Tablet, or both, since #14 was specifically only happening on a Jolla Tablet?

I'm using Jolla C.

I created a test build with a changed AES-Engine, which seems to be more stable after my limited Tests. You can get it here: https://mail.seiichiro0185.org/index.php/s/GJQoXPM5BNR2r6o

Decrypting the created files using the Terminal should work with:
base64 -d sailotp_20170319.aes | openssl enc -d -aes-256-cbc

Let me know If you see any improvements with the new build

I hit the same issue with the SailOTP app from the Jolla store; your temporary build gives legible JSON after decryption 👍

I see the same issue; tried to decrypt an exported tokens file, unsuccessfully.

[seiichiro0185]

Should be fixed (according to my tests) with Version 1.6. Also on some versions of openssl you may need an adapted command to decrypt the export file due to some changed defaults:

openssl enc -d -a -A -md md5 -aes-256-cbc -in sailotp_20160723.aes

I'm closing this issue, should it still be there feel free to reopen.

[physkets]

Can you make it so that the app displays instructions to decrypt when one exports? That will make it convenient for people unfamiliar with openssl.

[seiichiro0185]

I'll add the openssl commandline to the export screen in the next release.
