Hello, dear!
Have a nice day!
User accounts for logging in to Operation Portal and Maintenance Portal are stored after being encrypted.
The critical external interfaces support encryption.
OBS supports encryption. When uploading files using the OBS server side encryption mode, you can use the KMS encryption function to encrypt files. With this function, the files are automatically encrypted and stored on the cloud. During data use and download, only valid users who pass the identity authentication can obtain the KMS encryption key, which will be used to decrypt the stored data for plaintext.
Hope can help you!
