Documented steps
Run `mc encrypt set ALIAS/BUCKET` with an algorithm flag: `--enc-sse-s3` (SSE-S3 server-managed), `--enc-sse-kms` with `--key <name>` (SSE-KMS via KEK), or `--enc-sse-c` (SSE-C customer-provided keys).
MinIO AIStor then automatically encrypts all new objects written to that bucket using the selected default mode.
Verify with `mc encrypt info ALIAS/BUCKET` to show the current default encryption mode.
Remove the default with `mc encrypt clear ALIAS/BUCKET` so new objects are no longer auto-encrypted.
Known gotchas
SSE-S3 is the simplest default and needs no key management; SSE-KMS requires a configured KES/KMS server.
Default bucket encryption affects only NEW objects; existing objects are not retroactively re-encrypted.
SSE-C uses customer-provided 32-byte keys and `--enc-c` rejects `=`-padded RawBase64 keys - use a 64-byte hex key.
For per-request SSE on a specific upload use `mc cp --enc-c` or SDK put options rather than the bucket default.
