+## Encrypted Private Key

+MinIO supports encrypted KES client private keys. Therefore, you can use
+an password-protected private keys for `MINIO_KMS_KES_KEY_FILE`. 
+
+When using password-protected private keys for accessing KES you need to
+provide the password via:
+```
+export MINIO_KMS_KES_KEY_PASSWORD=<your-password>

+Certificates are no secrets and sent in plaintext as part of the TLS handshake.

+// An AWS S3 ETag is 16 bytes long and, in case of a multipart
+// upload, has a `-N` suffix encoding the number of object parts.
+// An ETag is not AWS S3 compatible when encrypted. When sending
+// an ETag back to an S3 client it has to be formatted to be
+// AWS S3 compatible.
+//
+// Therefore, Format returns the last 16 bytes of an encrypted
+// ETag.
+//
+// In general, a caller has to distinguish the following cases:
+//  - The object is a multipart object. In this case,
+//    Format returns the ETag unmodified.
+//  - The object is a SSE-KMS or SSE-C encrypted single-
+//    part object. In this case, Format returns the last
+//    16 bytes of the encrypted ETag which will be a random
+//    value.
+//  - The object is a SSE-S3 encrypted single-part object.
+//    In this case, the caller has to decrypt the ETag first
+//    before calling Format.
+//    S3 clients expect that the ETag of an SSE-S3 encrypted
+//    single-part object is equal to the object's content MD5.
+//    Formatting the SSE-S3 ETag before decryption will result
+//    in a random-looking ETag which an S3 client will not accept.

+// Hence, a caller has to check:
