All IAM APIs support HTTPS to encrypt data during transmission. Parent topic: Data Protection
Personal Data Storage IAM uses encryption algorithms to encrypt user data before storing it. Usernames and AKs: non-sensitive data, which is stored in plaintext. Passwords and SKs: encrypted Access Control Personal data is stored in the IAM database after being encrypted.
For example, when SSE-KMS is used to encrypt objects, OBS uses FAS to call KMS to decrypt the objects. When downloading an SSE-KMS encrypted object, the user directly calls OBS to obtain the object, instead of calling KMS to obtain the key to decrypt the object.
