Use client tools like `mc` to set and listen for event notifications using the [`event` sub-command](https://docs.min.io/community/minio-object-store/reference/minio-mc/mc-event-add.html). MinIO SDK's [`BucketNotification` APIs](https://docs.min.io/community/minio-object-store/developers/go/API.html#setbucketnotification-ctx-context-context-bucketname-string-config-notification-configuration-error) can also be used. The notification...

	// is unique for a sequence of bytes. See also compareSignatureV2.
	return subtle.ConstantTimeCompare([]byte(sig1), []byte(sig2)) == 1
}

// doesPolicySignatureMatch - Verify query headers with post policy
//   - http://docs.aws.amazon.com/AmazonS3/latest/API/sigv4-HTTPPOSTConstructPolicy.html
//
// returns ErrNone if the signature matches.
func doesPolicySignatureV4Match(formValues http.Header) (auth.Credentials, APIErrorCode) {

Esse é o benefício dos padrões...
