A utility for Magento 2 encryption key rotation and management. CVE-2024-34102(aka Cosmic Sting) victims can use it as an aftercare.
- Development usage
- Deployment automation
- CVE-2024-34102(aka Cosmic Sting) aftercare
After applying security patches, you need to perform a key rotation to completely deny the attacker's Admin level WebAPI access.
If you cannot upgrade or apply the official isolated patch, see Our Patches.
If the official encryption key rotation command php bin/magento encryption:key:change is not available, you can use this extension and this extension has more features as a "Key Manager".
This extension offers 3 commands.
- Generate new encryption key(for development/scripting purpose)
php bin/magento ww:encryption-key-manager:genkey [-f|--format FORMAT]
Example:
$ php bin/magento ww:encryption-key-manager:genkey
5f81fe506a1025b8ea439fd49c6fa8e3
- List all/newest encryption keys
php bin/magento ww:ekm:list [--newest]
Tip: you can use ekm shorthand for encryption-key-manager.
Example:
$ php bin/magento ww:ekm:list
Encryption key count: 3

- Encryption key rotation (most important)
php bin/magento ww:encryption-key-manager:rotate [-k|--key KEY]
Tip: if -k|--key is not provided, a random generated key will be used.
Example:
$ php bin/magento ww:encryption-key-manager:rotate
Encryption key has been rotated successfully.
Encryption keys are stored in `app/etc/env.php`. Caution: do not delete old keys!
Starting from version 2.4.7, encryption key format is changed from hex to base64.
New format example(note it has a base64 prefix):
base64bDr+HSz4tZ+cjZA89J5RvbZzCfDKWO1iXgDfmqeZL0c=
By default, php bin/magento ww:encryption-key-manager:genkey generates a key that is compatible with your current Magento version.
But you can force the format(for development purpose)
php bin/magento ww:encryption-key-manager:genkey --format base64
php bin/magento ww:encryption-key-manager:genkey --format hex
More details of the key generation process are in this blog post.
