Struct HashAlgorithmBuilder

pub struct HashAlgorithmBuilder;

Builder for constructing hash algorithm instances.

用于构建哈希算法实例的构建器。

Usage Pattern | 使用模式

The builder provides a fluent interface for algorithm selection:

构建器为算法选择提供流畅的接口：

use seal_crypto_wrapper::algorithms::hash::HashAlgorithm;

// General purpose
let sha256 = HashAlgorithm::build().sha256();

// High security
let sha384 = HashAlgorithm::build().sha384();

// Maximum security
let sha512 = HashAlgorithm::build().sha512();
