DartArgon2id class

Argon2id (RFC 9106) implemented in pure Dart.

The implementation uses DartArgon2State. You can use the state object directly if you are computing many hashes and want to minimize memory allocations.

You can control the number of created isolates with maxIsolates and minBlocksPerSliceForEachIsolate. The default values are usually good.

Examples

See documentation for the class Argon2id.
