Authenticated encryption
AES-256-GCM protects file confidentiality and authenticity using a server-side application key.
Cybte Secure Vault encrypts approved document types before storage and restricts retrieval to the authenticated account that uploaded them, with integrity checking and auditable access events.
The current MVP implements authenticated ownership checks, AES-256-GCM encryption, content-type restrictions, integrity verification and audit records.
AES-256-GCM protects file confidentiality and authenticity using a server-side application key.
Download and delete operations require an authenticated session and match documents to their owner.
A SHA-256 digest is checked after decryption before a document is returned to the user.
Upload, download and deletion events are recorded in a dedicated audit table.
File size and server-detected MIME type are validated before content is accepted.
Encrypted payloads default to a storage directory outside the public document root.
This is a functional MVP, not a certification claim. Before storing regulated or highly sensitive customer information, complete centralized key management, backup/recovery controls, malware scanning, MFA and independent penetration testing.
