AES加解密

以下是AES加解密Kotlin实现：

object AESCrypt {
    /**
     * AES加密
     */
    fun enCrypt(str: String, pwd: String): String {
        //创建cipher对象
        val cipher = Cipher.getInstance("AES")
        val secretKeySpec: SecretKeySpec? = SecretKeySpec(pwd.toByteArray(), "AES")
        cipher.init(Cipher.ENCRYPT_MODE, secretKeySpec)
        val enCryptRes = cipher.doFinal(str.toByteArray())
        val result = Base64.encode(enCryptRes)
        return result
    }


    /**
     * 解密
     */
    fun deCrypt(str: String, pwd: String): String {
        //创建cipher对象
        val cipher = Cipher.getInstance("AES")
        val secretKeySpec: SecretKeySpec? = SecretKeySpec(pwd.toByteArray(), "AES")
        cipher.init(Cipher.DECRYPT_MODE, secretKeySpec)
        val deCryptRes = cipher.doFinal(Base64.decode(str))
        val result = String(deCryptRes)
        return result
    }


}


fun main(args: Array<String>) {
    val str = "老婆我爱你"
    val pwd = "1234567812345678"

    val enCrypt = AESCrypt.enCrypt(str, pwd)
    println("加密后的结果：$enCrypt")
    val deCrypt = AESCrypt.deCrypt(enCrypt, pwd)
    println("解密后的结果：$deCrypt")

}
