Android使用facebook隐藏库加密plaint文本

概述我尝试使用以下代码加密明文.代码似乎加密了文本但它没有解密到明文.我究竟做错了什么？代码：Entityentity=newEntity("password");byte[]ciphertext=crypto.encrypt(("datatoencrypt").getBytes(),entity);plaintext=crypto.decrypt(ciphertext,entity)输出：Ecry

我尝试使用以下代码加密明文.代码似乎加密了文本但它没有解密到明文.我究竟做错了什么 ？

代码：

Entity entity = new Entity("password");byte[] ciphertext = crypto.encrypt(("data to encrypt").getBytes(),entity);plaintext = crypto.decrypt(ciphertext,entity)

输出：

Ecrypted text:[B@417a110Decrypted text:[B@417df20

解决方法:

以下代码可以加密/解密字符串

KeyChain keyChain = new SharedPrefsBackedKeyChain(context, CryptoConfig.KEY_256);crypto = AndroIDConceal.get().createDefaultCrypto(keyChain);public static String encrypt(String key, String value) throws KeyChainException, CryptoInitializationException, IOException {    ByteArrayOutputStream bout = new ByteArrayOutputStream();    OutputStream cryptoStream = crypto.getCipherOutputStream(bout, Entity.create(key));    cryptoStream.write(value.getBytes("UTF-8"));    cryptoStream.close();    String result = Base64.encodetoString(bout.toByteArray(), Base64.DEFAulT);    bout.close();    return result;}public static String decrypt(String key, String value) throws KeyChainException, CryptoInitializationException, IOException {    ByteArrayinputStream bin = new ByteArrayinputStream(Base64.decode(value, Base64.DEFAulT));    inputStream cryptoStream = crypto.getCipherinputStream(bin, Entity.create(key));    ByteArrayOutputStream bout = new ByteArrayOutputStream();    int read = 0;    byte[] buffer = new byte[1024];    while ((read = cryptoStream.read(buffer)) != -1) {        bout.write(buffer, 0, read);    }    cryptoStream.close();    String result = new String(bout.toByteArray(), "UTF-8");    bin.close();    bout.close();    return result;}
