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'sgetInstancemethod, and passes the name of the requestedtransform...

finalize in class java.lang.Object getAlgID public abstract AlgorithmIdentifier getAlgID() Builds an AlgorithmIdentifier that is a "snapshot" of the Cipher's current configuration. Altering this AlgorithmIdentifier will have no effect on the state of the Cipher. Returns: A newly constructed Algorit...
以上代码中,我们使用Scanner类来读取输入的文本和密钥。System.in表示从标准输入流中读取输入。 步骤2:生成密钥表 接下来,我们需要根据密钥生成密钥表。密钥表是一个包含26个字母的数组,用于加密和解密操作。以下是代码示例: importjava.util.Scanner;publicclassCipher{publicstaticvoidmain(String[]args){Scannerscanner...
