StartStreamEncryption

Enables or updates server-side encryption using an AWS KMS key for a specified stream.

Note

When invoking this API, you must use either the StreamARN or the StreamName parameter, or both. It is recommended that you use the StreamARN input parameter when you invoke this API.

Starting encryption is an asynchronous operation. Upon receiving the request, Kinesis Data Streams returns immediately and sets the status of the stream to UPDATING. After the update is complete, Kinesis Data Streams sets the status of the stream back to ACTIVE. Updating or applying encryption normally takes a few seconds to complete, but it can take minutes. You can continue to read and write data to your stream while its status is UPDATING. Once the status of the stream is ACTIVE, encryption begins for records written to the stream.

API Limits: You can successfully apply a new AWS KMS key for server-side encryption 25 times in a rolling 24-hour period.

Note: It can take up to 5 seconds after the stream is in an ACTIVE status before all records written to the stream are encrypted. After you enable encryption, you can verify that encryption is applied by inspecting the API response from PutRecord or PutRecords.

Request Parameters

The request accepts the following data in JSON format.

EncryptionType

The encryption type to use. The only valid value is KMS.

Type: String

Valid Values: KMS

Required: Yes

KeyId

The GUID for the customer-managed AWS KMS key to use for encryption. This value can be a globally unique identifier, a fully specified Amazon Resource Name (ARN) to either an alias or a key, or an alias name prefixed by "alias/".You can also use a master key owned by Kinesis Data Streams by specifying the alias aws/kinesis.

Key ARN example: arn:aws:kms:us-east-1:123456789012:key/12345678-1234-1234-1234-123456789012
Alias ARN example: arn:aws:kms:us-east-1:123456789012:alias/MyAliasName
Globally unique key ID example: 12345678-1234-1234-1234-123456789012
Alias name example: alias/MyAliasName
Master key owned by Kinesis Data Streams: alias/aws/kinesis

Length Constraints: Minimum length of 1. Maximum length of 2048.

Required: Yes

StreamARN

The ARN of the stream.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 2048.

Pattern: arn:aws.*:kinesis:.*:\d{12}:stream/\S+

Required: No

StreamName

The name of the stream for which to start encrypting records.

Type: String
