This feature is deprecated! We highly recommend generating your own keys and salts instead of relying on a remote service to do this for you.

If you have python installed, try running this command (all on one line):

python -c "import random; import string; r = random.SystemRandom(); print(chr(10).join('define( {q}{0}{q}{1}, {q}{2}{q} );'.format(key,' '*(16-len(key)),''.join(r.choice(string.ascii_letters+string.digits)for _ in range(64)),q=chr(39))for key in 'AUTH_KEY SECURE_AUTH_KEY LOGGED_IN_KEY NONCE_KEY AUTH_SALT SECURE_AUTH_SALT LOGGED_IN_SALT NONCE_SALT'.split(' ')))"

Or, if you're using a .env file for configuration (also recommended), try this:

python -c "import random; import string; r = random.SystemRandom(); print(chr(10).join('{0}={q}{1}{q}'.format(key,''.join(r.choice(string.ascii_letters+string.digits)for _ in range(64)),q=chr(34))for key in 'AUTH_KEY SECURE_AUTH_KEY LOGGED_IN_KEY NONCE_KEY AUTH_SALT SECURE_AUTH_SALT LOGGED_IN_SALT NONCE_SALT'.split(' ')))"
