Automated downloading handles file encryption and decryption through predefined workflows that integrate encryption standards and decryption keys into the download process. Here's how it works:
Encryption During Upload: Files are encrypted before or during upload using protocols like AES (Advanced Encryption Standard) or TLS (Transport Layer Security). For example, a file uploaded to a cloud storage service may be encrypted with AES-256 at rest.
Secure Transmission: During automated download, the file is transferred over an encrypted channel (e.g., HTTPS or SFTP) to prevent interception.
Decryption After Download: The downloaded file is decrypted using the corresponding key. This can be done automatically if the key is stored securely (e.g., in a key management system).
Example:
A company uses automated scripts to download daily reports from a secure server. The reports are encrypted with AES-256 before upload. The script authenticates with the server, downloads the file over HTTPS, and decrypts it using a pre-configured key stored in Tencent Cloud's Key Management Service (KMS).
For secure key management, Tencent Cloud KMS ensures encryption keys are stored and managed with strict access controls, supporting automated decryption workflows.
