 The following rules apply to all ciphers:
 
 - Providing only a `configId` without a `projectId` is not allowed. Similarly, providing only `branchType` without `projectId` is also not allowed.
-- Cipher decryption is only possible in the [region](/overview/api/#regions-and-endpoints) where the cipher was created. For example, ciphers with prefixes `KBC::ProjectSecureKV::` (Azure) or `KBC::ProjectSecureGKMS::` (GCP), instead of `KBC::ProjectSecure::` (AWS), use the same business logic but are specific to their region and technology and are not interchangeable.

 - There is no decryption API; the cipher is decrypted internally before a component is run.
 - Ciphering a value that is already encrypted does not change its encryption.
 - There is no way to retrieve the component, project, configuration ID, or branch type from the cipher.
