Lock down DRM keys. Unlock peace of mind.
License Cipher adds an extra layer of protection to Widevine and PlayReady, preventing client-side exploits and ensuring content and license integrity.
Trusted by the world’s most-recognized companies.
The challenge and the solution.
DRM license workflows are increasingly under attack.
When attackers extract keys, the impact goes beyond piracy. It undermines licensing agreements, erodes customer confidence, and exposes platforms to legal and compliance risks.
Problem
- Software-level DRM operates at a layer where it is susceptible to reverse engineering.
- Automated extraction tools target license exchanges to harvest keys at scale.
- Compromised Content Decryption Modules (CDMs) enable attackers to request valid licenses and the keys needed to decrypt the content.
- New attack methods are now available, exposing premium content to piracy.
DoveRunner License Cipher: The missing layer of DRM defense.
License Cipher introduces a dedicated protection layer that fortifies license transactions and prevents unauthorized access. It strengthens protection for DRM systems like Widevine and PlayReady, which can have CDM security vulnerabilities.
Solution
- Protects license exchanges against manipulation and tampering attempts.
- Validates client authenticity to block compromised or illegitimate requests.
- Defends against automated key-extraction tools that exploit client-side DRM weaknesses.
- Provides consistent safeguards across environments, ensuring premium content stays secure.
Choose the deployment that fits your infrastructure.
License Cipher delivers license-level protection through two deployment models, both designed to strengthen your existing DRM without replacing it.
| License Cipher Cloud | License Cipher Gateway |
|---|---|
Integrated protection for DoveRunner Multi-DRM customers
|
Standalone protection that integrates with any Multi-DRM solution
|
Protecting the license exchange at every step.
Ciphered Workflows
Every license request is encrypted and validated, blocking unauthorized or manipulated requests before they ever reach the server.
Whitebox Cryptography
Keys are embedded directly into obfuscated algorithms, ensuring secrets cannot be isolated, even with full client access.
Adaptive Client Validation
Dynamic authentication verifies device integrity and user authenticity on every request, reducing the risk of compromised CDMs.
Runtime Attack Protection
Built-in defenses detect and disrupt debugging, tampering, and injection attempts in real time across environments.
Cross-Platform SDKs
Dedicated SDKs for web, Android, Android TV, Universal Windows Platform, Samsung Tizen, and LG webOS deliver consistent protection without disrupting playback performance.

It has helped us a lot in putting a check on threats from hacker gaming platforms.
Verified user on Gartner
Its ability to obfuscate code is very good, it can also hide and mess up the whole directory tree, you can’t find any hardcode in the old app on it, even in the small code, it almost always encrypts the source code. It’s almost impossible to do any static analysis on it.
