非对称加密（RSA） ​

对于对称加密，目前我们仅提供了rsa相关函数：

since 0.5.2

js
fun rsaEncryptBase64(    data: String,    publicKey: String,): String 

fun rsaEncryptHex(    data: String,    publicKey: String,): String

fun rsaDecryptBase64(    data: String,    privateKey: String,): String

fun rsaDecryptHex(    data: String,    privateKey: String,): String

非对称加密（RSA）（新）@since v0.8.8 ​

预计在v0.8.8及之后提供新的的非对称加密支持！

提供全局类AsymmetricCrypto，其拥有的方法如下：

js
fun setPublicKey(key: ByteArray): T
fun setPublicKey(key: String): T
fun setPrivateKey(key: ByteArray): T
fun setPrivateKey(key: String): T

  

fun decrypt(data: Any, usePublicKey: Boolean? = true): ByteArray?
fun decryptStr(data: Any, usePublicKey: Boolean? = true): String?

  

fun encrypt(data: Any, usePublicKey: Boolean? = true): ByteArray?
fun encryptHex(data: Any, usePublicKey: Boolean? = true): String?
fun encryptBase64(data: Any, usePublicKey: Boolean? = true): String?

其中new AsymmetricCrypto(algorithm: String)

algorithm:

  • RSA
  • RSA/ECB/PKCS1Padding
  • RSA/ECB/NoPadding
  • RSA/None/NoPadding

使用举例：

  1. 使用公钥加密字符串：
js
var rsa = new AsymmetricCrypto('RSA/ECB/PKCS1Padding')  
rsa.setPublicKey('MFwwDQYJKoZIhvcNAQEBBQADSwAwSAJBAMbdeu9xLfvZg8E3h0vzQuN0VTzvaojqOOaXppoUQZ92vEAu7IFmbMoTGvfECdus3ivHOPJ2i/rmS1OnrNZ5UrkCAwEAAQ==');
var res = rsa.encryptBase64('123123', true)
log.log(res)

输出：Pl4nKRHJ3akKtyE6eT4xhrWGhkFThsmeiBUKClnDF+OCKoLR3WoCsB1Xlp29Q+Dm9wCwpAWJ2pQolSpiVKWOZg==

注意点：

  • 公钥不需要加-----BEGIN PUBLIC KEY-----，且中间没有换行
  • 公钥是Base64格式
  1. 使用私钥解密字符串
js
var rsa = new AsymmetricCrypto('RSA/ECB/PKCS1Padding')
rsa.setPrivateKey('MIIBPAIBAAJBAMbdeu9xLfvZg8E3h0vzQuN0VTzvaojqOOaXppoUQZ92vEAu7IFmbMoTGvfECdus3ivHOPJ2i/rmS1OnrNZ5UrkCAwEAAQJBAKunF2tAvVlril+oR5+WTYE5tC2R1tpxmkXoVsUegPpborrXE/SP1TIivtojkNHNnA93kKxNkrBmwTpqB4YGBYECIQD3cweJ2KiMfx9kWZOnzhDungftFFYyfDvqNw866uGNCQIhAM28qyPiP10lPeGGMp0/tVntso1UMIvTsTEa4RHUy7QxAiEAooLAQ66v2z2tvzj5OS6jfiL5b6F4jsV6j/LDJN2XbgkCIH5/yxq9OgijpXDNesGFMpSgunB7m33eI8z1of28waOBAiEA8q24KumgJ+8T9YRLcGUYpNK/bePIAwKY/LgPE6GhZFA=');
var res = rsa.decryptStr('wbbrCmI05ff3Gqt9P1yB7/Ht1ELI8HPR0c8l88CmgMbi6SE/yOx8mkBHoGO4cUs+x5DXdwQMF3qRdDt0bpL4eQ==', false)
log.log(res)

输出：123123

同样：

  • 私钥不需要加-----BEGIN RSA PRIVATE KEY----- 和 -----END RSA PRIVATE KEY-----
  • 私钥中间没有换行
  • 私钥是Base64格式
  • decryptStr第二个参数是false，代表是使用私钥，这主要作内部使用

使用CryptoJS @since v0.8.6 ​

@since v0.8.6

估计在v0.8.6及以上版本，会引入CryptoJS；

这样做的好处是：大多数网站进行加解密的库也是使用的CryptoJS，天然兼容性好！

CryptoJS的官网：https://cryptojs.gitbook.io/docs/

一些细节可以参考官网；下面，将以常见的加密方式举例；

MD5 ​

js
var res = CryptoJS.MD5('123456')
log.log(res.toString())

Output: e10adc3949ba59abbe56e057f20f883e

ShaX ​

js
var hash = CryptoJS.SHA1("123456");
log.log(hash.toString()) // 7c4a8d09ca3762af61e59520943dc26494f8941b
log.log(hash.toString(CryptoJS.enc.Base64)) // fEqNCco3Yq9h5ZUglD3CZJT4lBs=

var hash = CryptoJS.SHA256("123456");
log.log(hash.toString()) // 8d969eef6ecad3c29a3a629280e686cf0c3f5d5a86aff3ca12020c923adc6c92

var hash = CryptoJS.SHA512("123456");
log.log(hash.toString()) 
//a3253876aed6bc22d4a6ff53d8406c6ad864195ed144ab5c87621b6c233b548baeae6956df346ec8c17f5ea10f35ee3cbc514797ed7ddd3145464e2a0bab413

// ujJTh2rta8ItSm/1PYQGxq2GQZXtFEq1yHYhtsIztUi66uaVbfNG7IwX9eoQ817jy8UUeX7X3dMUVGTioLq0Ew==

Sha3 ​

js
var hash = CryptoJS.SHA3("123456", { outputLength: 512 });
log.log(hash.toString())

Output: 808d63ba47fcef6a7c52ec47cb63eb1b747a9d527a77385fc05c8a5ce8007586265d003b4130f6b0c8f3bb2ad89965a5da07289ba5d1e35321e160bea4f766f8

HmacX ​

var hash = CryptoJS.HmacMD5("Message", "Secret Passphrase");
log.log(hash.toString())//5e03d0c1b42ef0b7e61fb333f3993949
log.log(hash.toString(CryptoJS.enc.Base64))//XgPQwbQu8LfmH7Mz85k5SQ==

AES ​

aes是目前网站最常见的加密方式，其需要key, iv,mode

下面以加密字符串：123456 举例：

js
var key = CryptoJS.enc.Utf8.parse("1234567890009876");
var iv = CryptoJS.enc.Utf8.parse("1234567890009876");
var encrypted = CryptoJS.AES.encrypt("123456", key, {
  iv: iv,
  mode: CryptoJS.mode.CBC,
  padding: CryptoJS.pad.Pkcs7
});
log.log(encrypted.toString()) // Base64
var hexStr = encrypted.ciphertext.toString(); // Hex
log.log(hexStr)

Output:

fUp2G0ORpNqhmWpiTVhxPg==

7d4a761b4391a4daa1996a624d58713e

如上所写，aes加解密主要有两种格式，一种是Base64,一种是Hex（二进制）

mode可选：

  • CBC
  • CFB
  • CTR
  • OFB
  • ECB

Padding可选：

  • Pkcs7
  • Iso97971
  • AnsiX923
  • Iso10126
  • ZeroPadding
  • NoPadding

DES ​

js
var key = CryptoJS.enc.Utf8.parse("1234567890009876");
var iv = CryptoJS.enc.Utf8.parse("1234567890009876");
var encrypted = CryptoJS.DES.encrypt("123456", key, {
    iv: iv,
    mode: CryptoJS.mode.CBC,
    padding: CryptoJS.pad.Pkcs7
});
log.log(encrypted.toString()) // Base64
var hexStr = encrypted.ciphertext.toString(); // Hex
log.log(hexStr)

Output:

HUX+7VtHgb0=

1d45feed5b4781bd

注意：

内置的CryptoJS不并不是支持所有原生的方法，如果提示：

Error: Native crypto module could not be used to get secure random number. (crypto.js#56)

也就说明不支持！
