HarmonyOS DES加解密和JAVA加密后不一样？

发布于

尝试着使用了， Crypto Architecture Kit 中的 3DES 发现加解密和java不一样，请教下，对于下面的加解密方法该怎么翻译成 ArkTS ？

import org.apaches.commons.codec.binary.Base64
import java.net.URLEncoder
import java.security.SecureRandom
import javax.crypto.Cipher
import javax.crypto.SecretKey
import javax.crypto.SecretKeyFactory
import javax.crypto.spec.DESKeySpec
import javax.crypto.spec.IvParameterSpec
import javax.crypto.spec.SecretKeySpec

object SecurityUtil {
  //加密
  fun encryptByDES(data: String, password: String): String? {
    val cipher = Cipher.getInstance("DES")
    val datasource: ByteArray = data.toByteArray()
    val random = SecureRandom()
    val desKey = DESKeySpec(password.toByteArray())
    val keyFactory: SecretKeyFactory = SecretKeyFactory.getInstance("DES")
    val securekey: SecretKey = keyFactory.generateSecret(desKey)

    cipher.init(Cipher.ENCRYPT_MODE, securekey, random)
    return Base64.encodeBase64String(cipher.doFinal(datasource))
  }
    //解密 
    fun decryptByDES(srcc: String, password: String): ByteArray? {
    val src = Base64.decodeBase64(srcc)
    val random = SecureRandom()
    // 创建一个DESKeySpec对象
    val desKey = DESKeySpec(password.toByteArray())
    // 创建一个密匙工厂
    val keyFactory = SecretKeyFactory.getInstance("DES")
    // 将DESKeySpec对象转换成SecretKey对象
    val securekey = keyFactory.generateSecret(desKey)
    // Cipher对象实际完成解密操作
    val cipher = Cipher.getInstance("DES")
    // 用密匙初始化Cipher对象
    cipher.init(Cipher.DECRYPT_MODE, securekey, random)
    return cipher.doFinal(src)
  }
}

3DES算法的加解密过程分别是对明文/密文数据进行三次DES加密或解密，得到相应的密文或明文。参考链接：

目前支持3DES，还不支持DES（DES是不安全算法）。

三方库也可以实现DES的加解密，三方库参考链接：
