dargon2_flutter
A wrapper plugin over the dargon2 plugin to handle the platform-specific dart:ffi integrations for iOS and Android Uses the reference C implementation of Argon2, winner of the Password Hash Competition
Pure Objective-C iOS
If you're using Objective-C for the iOS portion of your application (created with Objective-C and no Swift code), there's a few extra steps:
- Open the Xcode workspace (type in
open iOS/Runner.xcworkspace
in the terminal in the project's root directory) - Right click the
Runner
directory (Folder, not project/workspace) - Click
New File
- Select
Swift File
in the prompt - (This is the Important Step) Select
Create Bridging Header
when the prompt comes up - You don't have to add anything to that swift file or the bridging header, but it needs to be there along with the bridging header in order for the plugin to compile correctly for iOS
Usage
High-level hashing and verification (for direct hashing & verification of byte arrays, check the example on dargon2)
void _hash() async {
var password = 'password';
//use Salt(List<int> bytes) for a salt from an Integer list
var s = Salt.newSalt();
//Hash with pre-set params (iterations: 32, memory: 256, parallelism: 2,
//length: 32, type: Argon2Type.i, version: Argon2Version.V13)
var result = await argon2.hashPasswordString(password, salt: s);
//Raw hash values available as int list, base 64 string, and hex string
var bytesRaw = result.rawBytes;
var base64Hash = result.base64String;
var hexHash = result.hexString;
//Encoded hash values available as int list and encoded string
var bytesEncoded = result.encodedBytes;
var stringEncoded = result.encodedString;
//Verify password (returns true/false), uses default type (Argon2Type.i)
var verified = await argon2.verifyHashString(password, stringEncoded);
}
