zeroward is a command-line zero-knowledge encryption command-line program to secure user files at all stages(locally, on transmission, and on rest(while they are stored on the cloud storages)), it meant to and for different cloud storage providers, but for the moment it is just integrated with Yandex Cloud Storage.

• Yandex Cloud Storage [:page_facing_up:] (https://cloud.yandex.com/en/services/storage)

• Secures (Encrypts) user files before uploading them to the cloud.
• Utilizes two keys for encryption/decryption:
  • A KEK (Key-Encryption-Key) to encrypt the DEK (Data-Encryption-Key).
  • The DEK is used to encrypt files and is attached to the file as metadata.
• The KEK is in the possession of the user.
• The KEK is generated from a passphrase defined by the user during the first use.
• The KEK is then stored securely on the user's system.
• Provides a user-friendly interface for interacting with objects/buckets on cloud storage.
• Uses the AES-256-GCM algorithm for file and key encryption.
