What is @aws-crypto/ie11-detection?

@aws-crypto/ie11-detection is a utility package designed to detect the presence of Internet Explorer 11 (IE11) and its specific cryptographic capabilities. This is particularly useful for applications that need to ensure compatibility with IE11's cryptographic features or need to provide fallbacks for unsupported features.

What are @aws-crypto/ie11-detection's main functionalities?

Detect IE11

This feature allows you to detect if the current browser is Internet Explorer 11. The `isMsWindow` function checks the window object to determine if it matches IE11's characteristics.

const { isMsWindow } = require('@aws-crypto/ie11-detection');

if (isMsWindow(window)) {
  console.log('This is IE11');
} else {
  console.log('This is not IE11');
}

Detect SubtleCrypto

This feature checks if the SubtleCrypto interface is supported in the current browser. SubtleCrypto is a Web Crypto API that provides cryptographic primitives.

const { supportsSubtleCrypto } = require('@aws-crypto/ie11-detection');

if (supportsSubtleCrypto(window)) {
  console.log('SubtleCrypto is supported');
} else {
  console.log('SubtleCrypto is not supported');
}

Detect MsCrypto

This feature checks if the MsCrypto interface is supported in the current browser. MsCrypto is a legacy API specific to Internet Explorer for cryptographic operations.

const { supportsMsCrypto } = require('@aws-crypto/ie11-detection');

if (supportsMsCrypto(window)) {
  console.log('MsCrypto is supported');
} else {
  console.log('MsCrypto is not supported');
}
