 If you need to use your DEK, you can decrypt it using the [Decrypt data operation](https://www.scaleway.com/en/developers/api/key-manager/#path-keys-decrypt-data) specifying the `kek_id` parameter used to encrypt it.
 
-Key Manager **does not allow the use of data encryption keys for data encryption**.
+**Key Manager does not handle direct data encryption**. It is specifically designed to **encrypt and decrypt Data Encryption Keys (DEKs) and is limited to processing inputs up to 64KB in size**.
 
 However, you can use the DEK independently from Key Manager, for example with the [Tink extension](/encrypt-decrypt-dek-/#encrypt-and-decrypt-data-with-tink-and-key-manager) or with [OpenSSL](/encrypt-decrypt-dek/#manually-encrypt-and-decrypt-data-with-a-key-manager-dek).
