Features

• Simple API
• Uses Web Workers in Web platforms to speed up parsing.
• Uses Isolate.run in other platforms

Why was this made?

Originally, it was created for the web platform to speed up digest creation through web workers. As parsing a large file in the main thread would freeze the app.

Example

From Uint8List file data

final Uint8List data = ...;

final String sha256 = await FileDigest(data).sha256();
final String sha512 = await FileDigest(data).sha512();

From String content

const input = 'Test content';
final String sha256 = await FileDigest.fromString(input).sha256();
final String sha512 = await FileDigest.fromString(input).sha512();
