Source §

impl SignatureAlgorithm

Source

pub fn into_wrapper(self) -> SignatureAlgorithmWrapper

Converts the algorithm enum into a concrete wrapper implementation.

将算法枚举转换为具体的包装器实现。

§Purpose | 目的

This method creates a wrapper that implements the signature algorithm trait, enabling actual cryptographic operations like key pair generation, message signing, and signature verification with type safety guarantees.

此方法创建一个实现签名算法 trait 的包装器，启用实际的密码操作，如密钥对生成、消息签名和签名验证，并提供类型安全保证。

§Returns | 返回值

A SignatureAlgorithmWrapper that can perform:

Key pair generation
Message signing
Signature verification
Algorithm introspection

可以执行以下操作的 SignatureAlgorithmWrapper：

密钥对生成
消息签名
签名验证
算法内省

§Examples | 示例

use seal_crypto_wrapper::algorithms::asymmetric::signature::SignatureAlgorithm;

let algorithm = SignatureAlgorithm::build().ed25519();
let signer = algorithm.into_wrapper();

// Generate key pair
let keypair = signer.generate_keypair()?;
let (public_key, private_key) = keypair.into_keypair();

// Sign a message
let message = b"Hello, World!";
let signature = signer.sign(message, &private_key)?;

// Verify the signature
signer.verify(message, &public_key, &signature)?;
