Magento's built in function to replace Crypt key will not work if you are still working with data that has already been encrypted with a different Crypt key. This is because magento adds an index position of the crypt key used from the crypt key array to the encrypted data. **E.g. Old Setup:** Crypt Key Array: ``` [ 0 => OLD_CRYPT_KEY ] ``` Previously Encrypted Data Value: **\[0\]**:34JHSDJ3H4JHDFJH34JJHFJHDFJHDF **(SUCCESS)** **New Setup:** If you use Magento's built-in feature to add a new crypt key, it will be added as the 2nd index of the array. Crypt Key Array: ``` [ 0 => NEW_CRYPT_KEY 1 => OLD_CRYPT_KEY ] ``` Previously Encrypted Data Value: **\[0\]**:34JHSDJ3H4JHDFJH34JJHFJHDFJHDF **(FAIL)** The index 0 (Zero) of the crypt key array is no longer the old encryption key thus it will fail to decrypt the data and give up. ### Solution [](#solution) This module adds the encryption key configured in magento admin as the first item in the crypt key array. `PLEASE NOTE: Any new data encrypted with the new encryption key will not decrypt` ### How to use [](#how-to-use) Simply install the module using composer. `composer require muhammadmian/magento-2-crypt-key-replace` **Admin Config** Set the following config to **YES** and configure your new crypt key `Store > Configuration > Advanced > System > Enable Crypt Key Override` Enjoy. ### Health Score 27 — LowBetter than 49% of packages Maintenance20 Infrequent updates — may be unmaintained Popularity16 Limited adoption so far Community9 Small or concentrated contributor base Maturity53 Maturing project, gaining track record Bus Factor1 Top contributor holds 50% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
