加密算法（自己写）java自己给明文密码加密

public static Map<String, String> getEncryptMapData() {
Map<String, String> map = new HashMap<String, String>();
map.put("0", "a");
map.put("1", "b");
map.put("2", "c");
map.put("3", "d");
map.put("4", "e");
map.put("5", "f");
map.put("6", "g");
map.put("7", "h");
map.put("8", "i");
map.put("9", "j");
return map;
}

2.加密算法

private static String encryptPassword(String password) {

String name = "";
for (int i = 0; i < password.length(); i++) {
name = name + getEncryptMapData().get(String.valueOf(password.charAt(i)));
}
return name;
}

public static void main(String[] args) {
System.out.println(encryptPassword("123456"));
}
