Question

我想在Android中将String转换为RSAPublicKey。我试过下面的代码，但它给出了异常。我想使用该键从键中提取模量和指数。

  String PUBLIC_KEY = "BgIAAACkAABSU0ExAAQAAAEAAQBJGj09Gbyl7BS/8MytvjBUUfaktW984VHHW4lSI9y2OwaeOq4qqSD6IOHU9HL/QtwZ+wELq28eAOQSnr11hifMf6zWjIsCBHOEpLNJjL3wxjl7dUBEGMJOeZj2rmcf8v7lP/rpAtO/G8wKXhAIKLIFxcChkXwQKbQbHQ/FtX2bwg==";


  byte[] keyBytes = DatatypeConverter.parseBase64Binary(PUBLIC_KEY);
  X509EncodedKeySpec keySpec = new X509EncodedKeySpec(keyBytes);
  KeyFactory keyFactory = KeyFactory.getInstance("RSA");
  PublicKey pubKey = keyFactory.generatePublic(keySpec);

异常
