Too Long; Didn't Read
The Web Crypto API is an interface allowing a script to use cryptographic primitives in order to build systems using cryptography. It's very easy to misuse these primitives, and the pitfalls involved can be subtle. Some browsers implemented an interface called 'Crypto' without having it well defined or being cryptographically sound. The API methods are now available on a new interface:SubtleCrypto.subtlecrypto.property. The new interface gives access to an object implementing it. The API is now available to browsers implementing the Web Crypto. API.
