If you’ve recently installed or upgraded phpMyAdmin on a Server, you may be displayed with this phpmyadmin blowfish_secret warning message.<\/p>\n\n\n\n
\"The configuration file now needs a secret passphrase (blowfish_secret).\"<\/code><\/pre>\n\n\n\nThis might be alarming, but it\u2019s actually a quick fix \u2014 and it\u2019s essential for security.<\/p>\n\n\n\n
What Is blowfish_secret?<\/strong><\/h2>\n\n\n\nphpMyAdmin uses cookie-based authentication by default. To secure this process, it encrypts credentials stored in cookies using the Blowfish cipher<\/strong>. For that encryption to work, a secret passphrase (called blowfish_secret) is required.<\/p>\n\n\n\nIf this value is missing or too short, phpMyAdmin will display a warning.<\/p>\n\n\n\n
Step-by-Step Fix<\/strong><\/h2>\n\n\n\n1. Locate the phpMyAdmin Configuration File<\/strong><\/h2>\n\n\n\nOn the server, locate the the main configuration file for phpMyAdmin<\/mark><\/a>. For example<\/p>\n\n\n\n\/var\/www\/phpmyadmin\/config.inc.php<\/strong><\/p>\n\n\n\nTo edit it, open the file with a text editor:<\/p>\n\n\n\n
vim \/var\/www\/phpmyadmin\/config.inc.php<\/code><\/pre>\n\n\n\nIf the file doesn\u2019t exist, make sure phpMyAdmin is properly installed.<\/p>\n\n\n\n
2. Generate a Secure Blowfish Secret<\/strong><\/h2>\n\n\n\nTo create a secure, 32-character random string, use the openssl command:<\/p>\n\n\n\n
openssl rand -base64 24<\/code><\/pre>\n\n\n\nThis will return a value like:<\/p>\n\n\n\n
rS43xKrJz7RPv7wHf+Y6v1HbUG1rAXqw<\/code><\/pre>\n\n\n\nCopy that value.<\/p>\n\n\n\n
3. Update the Config File<\/strong><\/h2>\n\n\n\nNow, find this line in config.inc.php:<\/p>\n\n\n\n
$cfg['blowfish_secret'] = ' ';<\/code><\/pre>\n\n\n\nAnd replace it with your generated key from the above command:<\/p>\n\n\n\n
$cfg['blowfish_secret'] = 'rS43xKrJz7RPv7wHf+Y6v1HbUG1rAXqw';<\/code><\/pre>\n\n\n\nMake sure the passphrase is exactly 32 characters<\/strong>, otherwise phpMyAdmin will still show a warning.<\/p>\n\n\n\nSave and exit the config.inc.php file <\/p>\n\n\n\n
4. Restart Apache (if needed)<\/strong><\/h2>\n\n\n\nAlthough not always required, it\u2019s good practice to restart your web server:<\/p>\n\n\n\n
systemctl restart apache2<\/code><\/pre>\n\n\n\nIf you’re using Nginx with PHP-FPM:<\/p>\n\n\n\n
systemctl restart php8.4-fpm\nsystemctl restart nginx<\/code><\/pre>\n\n\n\nNow, refresh phpMyAdmin in your browser. The warning about the missing blowfish secret should be gone.<\/p>\n\n\n\n
Conclusion<\/strong><\/h3>\n\n\n\nSetting the blowfish_secret is a small but critical security step. It ensures the credentials stored in cookies are encrypted, keeping your login sessions secure.<\/p>\n\n\n\n
