# @bfmeta/sign-util

    BFMeta 生成签名的工具包

## 使用

```node

export class CryptoHelper

  implements BFMetaSignUtil.CryptoHelperInterface

{

  async sha256(msg: string | Uint8Array) {

    if (msg instanceof Uint8Array) {

      return crypto.createHash("sha256").update(msg).digest();

    }

    return crypto

      .createHash("sha256")

      .update(new Uint8Array(Buffer.from(msg)))

      .digest();

  }

  async md5(data?: any): any {

    const hash = crypto.createHash("md5");

    if (data) {

      return hash.update(data).digest();

    }

    return hash;

  }

  async ripemd160(data?: any): any {

    const hash = crypto.createHash("ripemd160");

    if (data) {

      return hash.update(data).digest();

    }

    return hash;

  }

}

import { BFMetaSignUtil } from "@bfmeta/sign-util";

(async () => {

  const cryptoHelper = new CryptoHelper();

  const bfmetaSignUtil = new BFMetaSignUtil("c", Buffer as any, cryptoHelper);

  const keypair = await bfmetaSignUtil.createKeypair("123");

  const keypair2 = bfmetaSignUtil.createKeypairBySecretKey(keypair.secretKey);

  console.log(keypair2.publicKey.toString("hex"));

  // 获取公钥

  const publicKey = keypair.publicKey.toString("hex");

  console.log(publicKey);

  // 获取地址

  const address = bfmetaSignUtil.getAddressFromPublicKey(keypair.publicKey);

  console.log(address);

  console.log(bfmetaSignUtil.getAddressFromPublicKeyString(publicKey));

  // 校验地址

  console.log(bfmetaSignUtil.isAddress(address));

  console.log(bfmetaSignUtil.isAddress("abc"));

  // 生成签名

  const msg = new Uint8Array(Buffer.from("abc"));

  const signature = await bfmetaSignUtil.detachedSign(msg, keypair.secretKey);

  console.log(signature.toString("hex"));

  console.log(bfmetaSignUtil.signToString(msg, keypair.secretKey));

  // 验证签名

  const result = bfmetaSignUtil.detachedVeriy(msg, signature, keypair.publicKey);

  console.log(result);

})();
