Returns | 返回值

An XofWrapper that can:

• Create readers for streaming output
• Generate arbitrary-length pseudorandom data
• Support domain separation with salt and info parameters
• Provide algorithm introspection

可以执行以下操作的 XofWrapper：

• 为流式输出创建读取器
• 生成任意长度的伪随机数据
• 支持使用盐和信息参数的域分离
• 提供算法内省

Examples | 示例

use seal_crypto_wrapper::algorithms::xof::XofAlgorithm;
use seal_crypto_wrapper::prelude::XofAlgorithmTrait;

let algorithm = XofAlgorithm::build().shake128();
let xof = algorithm.into_wrapper();

// Create a reader with input key material
let mut reader = xof.reader(
    b"input_key_material",
    Some(b"optional_salt"),
    Some(b"context_info")
)?;

// Read different amounts of data
let key1 = reader.read_boxed(32);  // 32-byte key
let key2 = reader.read_boxed(16);  // 16-byte key
let nonce = reader.read_boxed(12); // 12-byte nonce
