PhpMyAdmin 4.6.6 OpenSSL error

Question

At launch of PhpMyAdmin 4.6.6 under the access dialog box, there is:

OpenSSL error: error:06065064:digital envelope routines:EVP_DecryptFinal_ex:bad decrypt

With PHP 7.1.1 or 7.0.15 or 5.6.30.

Answer 1

I confirm this is an issue on the upgrade, due to the cookie encryption. The error should disappear on the next login.

This will happen to users using openssl direcly (not via phpseclib) on upgrade.
