Android编程加密算法小结(AES、Base64、RAS加密算法)

System.out.println("public:n" + publicKeyString); String privateKeyString = getKeyString(privateKey);

System.out.println("private:n" + privateKeyString); //加解密类

Cipher cipher = Cipher.getInstance("RSA");//Cipher.getInstance("RSA/ECB/PKCS1Padding"); //明文

byte[] plainText = "我们都很好！邮件：@sina.com".getBytes(); //加密

cipher.init(Cipher.ENCRYPT_MODE, publicKey); byte[] enBytes = cipher.doFinal(plainText);

//通过密钥字符串得到密钥 publicKey = getPublicKey(publicKeyString);

privateKey = getPrivateKey(privateKeyString); //解密

cipher.init(Cipher.DECRYPT_MODE, privateKey); byte[]deBytes = cipher.doFinal(enBytes);

publicKeyString = getKeyString(publicKey); System.out.println("public:n" +publicKeyString);

privateKeyString = getKeyString(privateKey); System.out.println("private:n" + privateKeyString);

String s = new String(deBytes); System.out.println(s);

} }
