Web加密与安全为什么需要加密加密是为了保护信息的安全，防止有非法人员访问，篡改或破坏伪造信息。在如今的信息时代，为了保护用户及国家政府的权益，维护信息安全变得极其重要，为此，出现了一批批优秀的加密算法 Web也就是说，如果我们定义的密钥(我们可以通过 java.security.KeyPairGenerator.initialize(int keysize) 来定义密钥长度)长度为 1024(单位是位，也就是 bit)，生成的密钥长度就是 1024位 / 8位/字节 = 128字节，那么我们需要加密的明文长度不能超过 128字节 - 11 字节 = 117字节。 most interesting cell phoneWebJava Code Examples for java.security.keypairgenerator # genKeyPair() The following examples show how to use java.security.keypairgenerator #genKeyPair() .

"Web数字签名大概可已描述为：用私钥加密，用公钥解密。发布一条交易信息：“我给xxx转了0.2个比特币”，将这条消息用自己的私钥加密，再发布出去，大众在收到这条消息后，用我的公钥验签，验证成功则说明是我发布的交易。1、加密保证了数据接受方的数据安全性。 " - Keypairgenerator.getinstance algorithm
