Enum KdfAlgorithm

pub enum KdfAlgorithm {
    Key(KdfKeyAlgorithm),
    Password(KdfPasswordAlgorithm),
}

Key Derivation Function algorithm enumeration.

密钥派生函数算法枚举。

Algorithm Selection | 算法选择

This enum provides access to two main categories of KDF algorithms:

此枚举提供对两个主要 KDF 算法类别的访问：

• Key-based: For deriving keys from existing high-entropy key material

• Password-based: For deriving keys from user passwords or low-entropy sources

• 基于密钥: 用于从现有高熵密钥材料派生密钥

• 基于密码: 用于从用户密码或低熵源派生密钥

Usage Examples | 使用示例

use seal_crypto_wrapper::algorithms::kdf::KdfAlgorithm;

// Key-based derivation (high entropy input)
let hkdf = KdfAlgorithm::build().key().hkdf_sha256();

// Password-based derivation (low entropy input)
let pbkdf2 = KdfAlgorithm::build().passwd().pbkdf2_sha256_with_params(10000);
let argon2 = KdfAlgorithm::build().passwd().argon2_with_params(65536, 3, 4);

Variants

Key(KdfKeyAlgorithm)

Key-based derivation functions for high-entropy inputs.

用于高熵输入的基于密钥的派生函数。

Suitable when the input key material already has sufficient entropy, such as cryptographic keys, shared secrets, or random values.

适用于输入密钥材料已具有足够熵的情况， 如密码密钥、共享密钥或随机值。

Password(KdfPasswordAlgorithm)

Password-based derivation functions for low-entropy inputs.

用于低熵输入的基于密码的派生函数。

Designed to handle user passwords and other low-entropy sources, with built-in protection against brute-force attacks.

设计用于处理用户密码和其他低熵源， 内置对暴力攻击的保护。
