FIEB_PASSWORD_ENCRYPT 是一种加密算法,它可以将密码进行加密,以保证密码在传输或存储时的安全性。下面是 Java 实现 FIEB_PASSWORD_ENCRYPT 的代码:
```java
public class FiebPasswordEncrypt {
private static final int[] FIEB_PASSWORD_ENCRYPT_KEY = { 10, 20, 30, 40, 50, 60, 70, 80, 90, 100 };
public static String encrypt(String password) {
char[] passwordChars = password.toCharArray();
StringBuilder encryptedPassword = new StringBuilder();
for (int i = 0; i < passwordChars.length; i++) {
int charValue = passwordChars[i];
int keyValue = FIEB_PASSWORD_ENCRYPT_KEY[i % 10];
int encryptedCharValue = charValue ^ keyValue;
encryptedPassword.append((char) encryptedCharValue);
}
return encryptedPassword.toString();
}
public static String decrypt(String encryptedPassword) {
char[] encryptedChars = encryptedPassword.toCharArray();
StringBuilder password = new StringBuilder();
for (int i = 0; i < encryptedChars.length; i++) {
int encryptedCharValue = encryptedChars[i];
int keyValue = FIEB_PASSWORD_ENCRYPT_KEY[i % 10];
int charValue = encryptedCharValue ^ keyValue;
password.append((char) charValue);
}
return password.toString();
}
}
```
该算法采用异或运算,通过一个固定的加密密钥对密码进行加密,并且加密密钥是固定的。在进行加密和解密时,需要使用相同的密钥才能得到正确的结果。
