SPEKE
Axinom Key Service supports an AWS protocol for key acquisition called SPEKE (Secure Packager and Encoder Key Exchange).
The integration endpoint is /Speke
of the Key Acquisition API (or /SpekeV2
for the SPEKE 2.0).
See also:
- Online tool for executing SPEKE requests
- Sample code for requesting keys using SPEKE v2
- Sample code for requesting keys using SPEKE v1
Functionalityβ
The Client requests one or more content keys. The Key Service generates the necessary keys using the Key Seed model and returns the keys with additional DRM-specific metadata where needed.
Authorizationβ
This endpoint requires an authorization header - the same as described under the Key Service Management API.
Request/Response Formatβ
The original SPEKE version is 1.0. Since March 2021, AWS also supports the version 2.0.
SPEKE 2.0 brings the following evolutions compared to SPEKE v1.0:
- Support for multiple content keys
- All tags from the SPEKE XML namespace are deprecated in favor of equivalent tags in the CPIX XML namespace
SPEKE:ProtectionHeader
is deprecated and replaced byCPIX:DRMSystem.SmoothStreamingProtectionHeaderData
CPIX:URIExtXKey
,SPEKE:KeyFormat
andSPEKE:KeyFormatVersions
are deprecated and replaced byCPIX:DRMSystem.HLSsignallingData
CPIX@id
is replaced byCPIX@contentId
- New mandatory CPIX attributes:
CPIX@version
,ContentKey@commonEncryptionScheme
- New optional CPIX element:
DRMSystem.ContentProtectionData
- Cross-versioning mechanism between SPEKE and CPIX
- HTTP headers evolution: new
X-Speke-Version
header,Speke-User-Agent
header renamed toX-Speke-User-Agent
- Heartbeat API deprecation
Axinom Key Service supports both versions: 1.0 and 2.0, there are two separate endpoints. Below, you can find request/response samples for both versions.
In both cases, the Client creates a CPIX document in the format which it desires to get, just without the values for the keys, and sends this document to the Key Service. The Key Service generates the specified keys, adds this information to the document, and returns the CPIX document to the Client.
SPEKE 2.0β
For SPEKE 2.0 to work, you need to add the following HTTP Header to your request:
X-Speke-Version: 2.0

ContentKeyPeriodList | A list of the ContentKeyPeriod elements. |
ContentKeyUsageRuleList | Content key usage rules for the key. Itβs a pass-through that will only be returned to the Client. |

How to get the KeyID?β
Packagers, when they request encryption keys from a Key Service, usually generate the related KeyID automatically. Itβs important for the downstream DRM processes to know the Key ID, but not all packagers report the assigned Key ID back to the user. For example, AWS doesnβt report the Key ID.
They Key ID can be extracted from the created DASH/HLS manifest, but this can be inconvenient and can only be done after packaging is completed.
There are two possible workarounds for this issue.
It is possible to override the Key ID assigned by a packager by supplying a flag: ?overrideKeyIds=true
. The new Key ID is then generated using a deterministic algorithm, see SPEKE Override Functionality.
An alternative solution can be a proxy which sits between a packager and the Key Service and reports the Key ID. Read Extracting Key ID from SPEKE requests for guidelines.
Encryption Schemesβ
In SPEKE 2.0 the attribute commonEncryptionScheme
is mandatory for each requested key.
Values supported for 'commonEncryptionScheme' and each of the DRM technologies
Scheme | Widevine | PlayReady | FairPlay |
---|---|---|---|
cenc | X | X | |
cbcs | X | X | X |
cens | X | ||
cbc1 | X |
For SPEKE 1.0, If 'CMAF' is used with the encryption method 'AES-CBC subsample', the optional 'protectionScheme' parameter in the Key Service URL must be set to 'cbcs'.
