JAVA常用加密解密算法Encryption and decryption 加密,是以某种特殊的算法改变原有的信息数据,使得未授权的用户即使获得了已加密的信息,但因不知解密的方法,仍然无法了解信息的内容。大体上分为双向加密和单向加密,而双向加密又分为对称加密和非对称加密(有些资料将加密直接分为对称加密和非对称加密)。 双向加密大体意...
DES(Data Encryption Standard):数据加密标准,速度较快,适用于加密大量数据的场合。 3DES(Triple DES):是基于DES,对一块数据用三个不同的密钥进行三次加密,强度更高。 AES(Advanced Encryption Standard):高级加密标准,是下一代的加密算法标准,速度快,安全级别高,支持128、192、256、512位密钥的加密。 算法特征 ...

This blog entry shows how to securely configure basic encryption/decryption primitives, the third entry in a blog series on using Java cryptography securely.
Cryptography is a method of protecting data and communications using codes and digital keys to ensure that the information is delivered untampered to the intended sender for further processing. Understanding the core ideas of cryptography, such as encryption and decryption, is critical for a developer...
对称加密 维基百科的解释如下： 对称密钥加密（英语：Symmetric-key algorithm）又称为对称加密、私钥加...
JCE(Java Cryptography Extension)是一组包,它们提供用于加密、密钥生成和协商以及 Message Authentication Code(MAC)算法的框架和实现。 它提供对对称、不对称、块和流密码的加密支持,它还支持安全流和密封的对象。它不对外出口,用它开发完成封装后将无法调用。 安装JCE步骤: 1、下载JCE压缩包: 压缩包里有以下文件...
This class provides the functionality of a cryptographic cipher for encryption and decryption. It forms the core of the Java Cryptographic Extension (JCE) framework. In order to create a Cipher object, the application calls the Cipher's getInstance method, and passes the name of the requested ...
