SubtleCrypto class
Secure context: This feature is available only in secure
contexts (HTTPS), in some or all supporting browsers.
The interface of the Web Crypto API provides a number of
low-level cryptographic functions. Access to the features of is
obtained through the subtle property of the Crypto object you
get from the crypto property.
Warning: This 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. Please learn and experiment, but don't guarantee or imply the security of your work before an individual knowledgeable in this subject matter thoroughly reviews it. The Crypto 101 Course can be a great place to start learning about the design and implementation of secure systems.
