Java如何使用StandardPBEByteEncryptor加密或解密字节信息？
这段代码演示了如何使用StandardPBEByteEncryptor该类来加密和解密字节信息。
package org.nhooo.example.jasypt;
import org.jasypt.encryption.pbe.StandardPBEByteEncryptor;
import java.util.Arrays;
public class ByteEncryptorDemo {
public static void main(String[] args) {
String text = "The quick brown fox jumps over the lazy dog";
System.out.println("Text = " + Arrays.toString(text.getBytes()));
StandardPBEByteEncryptor encryptor = new StandardPBEByteEncryptor();
encryptor.setAlgorithm("PBEWithMD5AndDES");
encryptor.setPassword("HelloWorld");
byte[] encrypted = encryptor.encrypt(text.getBytes());
System.out.println("Encrypted = " + Arrays.toString(encrypted));
byte[] original = encryptor.decrypt(encrypted);
System.out.println("Original = " + Arrays.toString(original));
}
}我们的代码的结果是：
Text = [84, 104, 101, 32, 113, 117, 105, 99, 107, 32, 98, 114, 111, 119, 110, 32, 102, 111, 120, 32, 106, 117, 109, 112, 115, 32, 111, 118, 101, 114, 32, 116, 104, 101, 32, 108, 97, 122, 121, 32, 100, 111, 103] Encrypted = [-63, -127, 0, 50, 98, 79, 58, 20, 54, -13, -104, -80, 21, 100, 42, 27, 121, 84, 46, 107, -37, 119, -107, -25, 118, -46, -128, -31, -20, -114, 34, -121, 66, 105, 45, 38, 79, 90, 41, -128, -128, -48, 113, 69, -10, 63, 95, -43, 46, -10, 57, -61, -16, 49, -57, -120] Original = [84, 104, 101, 32, 113, 117, 105, 99, 107, 32, 98, 114, 111, 119, 110, 32, 102, 111, 120, 32, 106, 117, 109, 112, 115, 32, 111, 118, 101, 114, 32, 116, 104, 101, 32, 108, 97, 122, 121, 32, 100, 111, 103]
