Web Crypto API: A Low-Level Interface for Internet Security

The Web Crypto API is an interface allowing a script to use cryptographic primitives in order to build systems using cryptography.

The Web Crypto API is an interface allowing a script to use cryptographic primitives in order to build systems using cryptography.

Warning: The Web Crypto API provides a number of low-level cryptographic primitives. It's very easy to misuse them, and the pitfalls involved can be very subtle.

Even assuming you use the basic cryptographic functions correctly, secure key management and overall security system design are extremely hard to get right, and are generally the domain of specialist security experts.

Errors in security system design and implementation can make the security of the system completely ineffective.

If you're not sure you know what you are doing, you probably shouldn't be using this API.
