Ionic2中的AES实现

Question

我已实施AES加密。请找到以下代码

   import { Injectable } from '@angular/core';
import CryptoJS from 'crypto-js';

@Injectable()
export class AesProvider {
  key: any = '';
  constructor() {
    this.key = 'asfda75vzv866@#$#';//CryptoJS.enc.Hex.parse("asfda75vzv866@#$#");
  }

  padOrTruncate(str: string): string {
    let result: string = '';
    if (str.length % 32 == 0)
      return str;
    result = str + '';
    while (!(result.length % 32 == 0)) {
      result = result + " ";
    }
    return result;
  }

  encrypt(plainText): string {
    let text = this.padOrTruncate(plainText);
    let encrypted = CryptoJS.AES.encrypt(text, this.key, {
            mode: CryptoJS.mode.ECB,
            padding: CryptoJS.pad.NoPadding
          });
  return CryptoJS.enc.Hex.stringify(encrypted.ciphertext);
}

decrypt(encryptedText): string {
  let decrypted = CryptoJS.AES.decrypt(encryptedText, this.key, {
                                        mode: CryptoJS.mode.ECB,
                                        padding: CryptoJS.pad.NoPadding
                                      }).toString();                             


 //var plaintext = decrypted.toString(CryptoJS.enc.Utf8);

  return decrypted;

}
}

问题是解密文本与纯文本不同。有人可以帮帮我吗？

1. 如何为用户生成私钥和公钥？

谢谢和问候
