[IC-Auth](https://github.com/ldclabs/ic-auth) is a web authentication system based on the Internet Computer.

`ic_auth_types` is a Rust types library used for integrating with IC-Auth. It provides essential data structures and utilities for working with Internet Computer authentication.

## Features

- **Efficient Byte Handling**: Includes `ByteBufB64` and `ByteArrayB64` types for efficient serialization and deserialization of binary data with automatic Base64URL encoding for human-readable formats.
- **Unique Identifiers**: Provides `Xid` type, a compact and lexicographically sortable globally unique identifier (12 bytes vs UUID's 16 bytes).
- **Authentication Primitives**: Includes types for delegations, signed delegations, and authentication responses.
- **Candid Compatibility**: All types implement `CandidType` for seamless integration with the Internet Computer.
- **Serde Support**: Full serialization/deserialization support for both human-readable (JSON) and binary formats (CBOR).

## Usage

Add this to your `Cargo.toml`:
```toml
[dependencies]
ic_auth_types = "0.4"
```

Enables interoperability with the original `xid` crate:
```toml
[dependencies]
ic_auth_types = { version = "0.4", features = ["xid"] }
```
