2,可逆: 按秘钥数量和加密规则分为:对称加密和非对称加密 1,对称加密:即通过key加密,也可以通过key来解密 优点:算法公开、计算量小、加密速度快、加密效率高 缺点:双方都使用同样的密钥,密钥可以自己指定,并且只有一把,如果密钥泄漏数据就会被解密 DES,AES 高级加密标准(英语:Advanced Encryption Standard,缩写:AES...
Java can help reduce costs, drive innovation, & improve application services; the #1 programming language for IoT, enterprise architecture, and cloud computing.
4.AES(Advanced Encryption Standard) 加密/解密 高级加密标准(英语:Advanced Encryption Standard,缩写:AES),在密码学中又称 Rijndael 加密法,是美国联邦政府采用的一种区块加密标准。这个标准用来替代原先的 DES,已经被多方分析且广为全世界所使用。简单说就是 DES 的增强版,比 DES 的加密强度更高。 AES 与 DES...
高级加密标准(英语:Advanced Encryption Standard,缩写:AES),是一种区块加密标准。这个标准用来替代原先的DES,已经被多方分析且广为全世界所使用。 那么为什么原来的DES会被取代呢,,原因就在于其使用56位密钥,比较容易被破解。而AES可以使用128、192、和256位密钥,并且用128位分组加密和解密数据,相对来说安全很多。完...
Keystores are available to applications that need data for authentication, encryption, or signing purposes.Applications can access a keystore via an implementation of the KeyStore class, which is in the java.security package. The recommended keystore type (format) is "pkcs12", which is based ...
Another is the SealedObject class, which uses encryption to hide the content of an object. GuardedObject is a general way to enforce access control at a per class/object per method level. This method, however, should be used only selectively, partly because this type of control can be ...
Enables the use of KEMs in higher level protocols such as Transport Level Security (TLS) and in cryptographic schemes such as Hybrid Public Key Encryption (HPKE, RFC 9180). Allows security providers to implement KEM algorithms in either Java code or native code. Includes an implementation of ...

er与ee后缀的常见词是employer(雇主)/employee(雇员)、caller(调用者)/callee(被调用者)。 具体使用方式见下面的说明。 1. 简单使用 父线程给子线程传递值。 示例代码: TransmittableThreadLocal<String>context=newTransmittableThreadLocal<>();// ===// 在父线程中设置context.set("value-set-in-parent");/...
Some situations require strong random values, such as when creating high-value/long-lived secrets like RSA public/private keys. To help guide applications in selecting a suitable strong SecureRandom implementation, Java distributions include a list of known strong SecureRandom implementations in the secur...
