not able to decrypt using the key from /flash/secure/key.txt

[tanishqjasoria]

I got the key: RRIOTJI00000524XXXXXXXXXXXXXXXXXXXXXXXXXXXX (<32 char string>) then i used this command to decrypt the back up file: openssl aes-128-cbc -d -pass file:key.txt -in RRIOTJI00000524_JCOW411.enc -out RRIOTJI00000524_JCOW411.txt openssl aes-128-cbc -d -md md5 -pass file:key.txt -in RRIOTJI00000524_JCOW411.enc -out RRIOTJI00000524_JCOW411.txt had the same error

Using -iter or -pbkdf2 would be better.

apparently it was not needed - found the server.key in the firmware and it decrypted using that. EDIT: it only decrypted the dbglog file and not the config file.

@Gangadhararao29 You can definitely downgrade your firmware from the WEB-UI and get root if you want.
