MinIO Security Overview
MinIO encrypts data when stored on disk and when transmitted over the network. MinIO’s state-of-the-art encryption schemes support granular object-level encryption using modern, industry-standard encryption algorithms, such as AES-256-GCM, ChaCha20-Poly1305, and AES-CBC. MinIO is fully compatible with S3 encryption semantics, and also extends S3 by including support for non-AWS key management services such as Hashicorp Vault, Gemalto KeySecure, and Google Secrets Manager.
