You can update the name and description of symmetric and asymmetric keys in Key Management Service (KMS). For symmetric keys, you can also update the key rotation period. You can’t update the algorithm of an existing key. Create a new key if you need to use a different algorithm.

​
Prerequisites

Make sure you are in a group that has at least the editor role within your tenant or project; for example, the default editors group. Alternatively, you can have an access permit with the editor role assigned to the required key. To check your access rights, go to the Administration → IAM section in the web console.
