RSA公钥加解密、AES加解密

 jsencrypt 只能公钥加密私钥解密

//安装依赖
npm install jsencrypt --save

import JsEncrypt from "jsencrypt"; //rsa加密
//公钥加密
export function RSAencrypt(pas) {
	//实例化jsEncrypt对象
	let jse = new JsEncrypt();
	//设置公钥
	jse.setPublicKey(
		"-----BEGIN PUBLIC KEY-----\n" +
	
		"-----END PUBLIC KEY-----"
	);
	//加密
	return jse.encrypt(pas);
}

export function RSAdecrypt(pas) {
	let jse = new JsEncrypt();
	// jse.setPrivateKey(
	jse.setPublicKey(
		"-----BEGIN PUBLIC KEY-----\n" +
		

		"-----END PUBLIC KEY-----"
	);
	return jse.decrypt(pas);
}

node-rsa 实现RSA解密

npm install node-rsa --save

export function decrypt(txt) {
	//公钥解密
	let privateKey = "-----BEGIN PUBLIC KEY-----\n" +
		"-----END PUBLIC KEY-----"
	try {
		const nodersa2 = new NodeRSA(privateKey);
		const decrypted2 = nodersa2.decryptPublic(txt, "utf8");
		return decrypted2
	} catch (error) {
		return ''
	}
}

export const encrypt = (password) => {
	// 私钥加密
	//  '-----BEGIN PRIVATE KEY-----\n'   '\n-----END PRIVATE KEY-----' 必须写
	let publicKey = '-----BEGIN PRIVATE KEY-----\n' + '***' + '\n-----END PRIVATE KEY-----'
	const nodersa = new NodeRSA(publicKey);
	const decrypted = nodersa.encryptPrivate(password, 'base64', "utf8");
	return decrypted
}

AES 加解密

npm install crypto-js --save
// 加密
export function AESencrypt(sing, data) {
	let secretKey = CryptoJS.enc.Utf8.parse(sing);
	let ciphertext = CryptoJS.AES.encrypt(JSON.stringify(data), secretKey, {
		mode: CryptoJS.mode.ECB,
		// iv: CryptoJS.enc.Utf8.parse("3zyJFPEzh5rUeUNi"),
		padding: CryptoJS.pad.Pkcs7,
	}).toString();
	return ciphertext;
}

//解密
export function AESdecrypt(sing, data) {
	let secretKey = CryptoJS.enc.Utf8.parse(sing);
	let bbb = CryptoJS.AES.decrypt(data, secretKey, {
		mode: CryptoJS.mode.ECB,
		// iv: CryptoJS.enc.Utf8.parse("3zyJFPEzh5rUeUNi"),
		padding: CryptoJS.pad.Pkcs7,
	});
	return CryptoJS.enc.Utf8.stringify(bbb);
}

生成随机字符串作为sign

export function generateRandomString(length) {
	const characters =
		"ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789";
	let result = "";
	const charactersLength = characters.length;
	for (let i = 0; i < length; i++) {
		result += characters.charAt(Math.floor(Math.random() * charactersLength));
	}
	return result;
}
