example/example.md

Example

By default csp_hasher will hash scripts tags in the given html with sha256

Example 1

import 'dart:io';
import 'package:csp_hasher/csp_hasher.dart';

void main() {
    final cspHashes = hashScripts(File('mySuperNice.html'));
    print(cspHashes.first); // sha256-<hash>
    print(cspHashes.first.hash); // The base64 encoded hash
    print(cspHashes.first.hashType); // The hash type which is sha256 by default
    print(cspHashes.first.lineNumber); // Gives you the line number of the script tag in the html
    print(cspHashes.first.hashMode); // Gives you type which can be style or script
}

Example 2

If you want to change the hash type you can do so by passing the hashType parameter to the hashScripts function.

import 'dart:io';
import 'package:csp_hasher/csp_hasher.dart';

void main() {
    final cspHashes = hashScripts(File('mySuperNice.html'), hashType: sha384);
    print(cspHashes.first); // sha384-<hash>

    final cspHashes = hashScripts(File('mySuperNice.html'), hashType: sha512);
    print(cspHashes.first); // sha512-<hash>
}

Example 3

If you want to hash style tags you can do so by passing the hashMode parameter to the hashScripts function.

import 'dart:io';
import 'package:csp_hasher/csp_hasher.dart';

void main() {
    final cspHashes = hashScripts(File('mySuperNice.html', hashMode: HashMode.style);
    print(cspHashes.first.hashMode); // HashMode.style
}
