The principle holds that a cryptosystem should be secure, even if everything about the system, except the key, is public knowledge. This concept is widely embraced by cryptographers, in contrast to security through obscurity, which is not.

Secrets are being used everywhere nowadays, especially with the popularity of the DevOps movement. Application Programming Interface (API) keys, database credentials, Identity and Access Management (IAM) permissions, Secure Shell (SSH) keys, certificates, etc. Many organizations have them hardcoded within the source code in plaintext, littered thro...
Building, testing and deploying changes generally requires access to many systems. Continuous Integration (CI) and Continuous Deployment (CD) tools typically store secrets to provide configuration to the application or during deployment. Alternatively, they interact heavily with the secrets management system. Various best practices can help smooth ...
For cloud providers, there are at least four essential topics to touch upon: 1. Designated secret storage/management solutions. Which service(s) do you use? 2. Envelope & client-side encryption 3. Identity and access management: decreasing the blast radius 4. API quotas or service limits
You can enrich containers with secrets in multiple ways: build time (not recommended) and during orchestration/deployment.
In this section, we will discuss implementation. Note that it is always best to refer to the official documentation of the secrets management system of choice for the actual implementation as it will be more up to date than any secondary document such as this cheat sheet.
Secrets Management goes hand in hand with encryption. After all, secrets must be stored encrypted somewhere to protect their confidentiality and integrity.
There are many approaches to secrets detection and some very useful open source projects to help with this. The Yelp Detect Secrets project is mature and has signature matching for around 20 secrets. For more information on other tools to help you in the detection space, check out the Secrets Detectiontopic on GitHub.
Quick response in the event of a secret exposure is perhaps one of the most critical considerations for secrets management.
Sep 5, 2024 · Key rotation involves the periodic replacement of old keys with new ones on a scheduled basis, in order to reduce the impact a key exposure or compromise may cause. This practice ensures that in the event of a key compromise, the usefulness of such a key is confined by the rotation policy.
Mar 15, 2024 · The exposure of API secret keys, which authenticate and authorize requests to your API, to outsiders can jeopardize the security and privacy of your application and have a substantial financial impact - think $17M we discovered via one exposed Stripe token.
Oct 23, 2019 · By Jackson Bates. The Problem. All you want to do is fetch some JSON from an API endpoint for the weather, some book reviews, or something similarly simple. The fetch query in your front-end is easy enough, but you have to paste your secret API key right there in the front-end code for anybody to find with a trivial amount of digging!
