Kinesis / Client / stop_stream_encryption



Disables server-side encryption for a specified stream.


When invoking this API, it is recommended you use the StreamARN input parameter rather than the StreamName input parameter.

Stopping 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. Stopping 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, records written to the stream are no longer encrypted by Kinesis Data Streams.

API Limits: You can successfully disable 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 no longer subject to encryption. After you disabled encryption, you can verify that encryption is not applied by inspecting the API response from PutRecord or PutRecords.

Request Syntax

response = client.stop_stream_encryption(
  • StreamName (string) – The name of the stream on which to stop encrypting records.

  • EncryptionType (string) –


    The encryption type. The only valid value is KMS.

  • KeyId (string) –


    The GUID for the customer-managed Amazon Web Services 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

  • StreamARN (string) – The ARN of the stream.
