### 3. 随机生成器 (`random`)
|
||||
### 3. 文件创建与保存 (`file/CreateFile`)
|
||||
|
||||
支持创建普通/二进制文件,以及异步字节流文件保存。
|
||||
|
||||
| 方法 | 说明 | 参数 |
|
||||
|-------------------------------------------------------|---------------------------------------|-------------------------------------------------------------|
|
||||
| `CreateFile.NewFile(FileName, isBin, binFileType)` | 创建空白文件,二进制文件自动写入文件头 | `FileName` 文件名,`isBin` 是否二进制,`binFileType` 二进制类型(普通文件传 `null`) |
|
||||
| `CreateFile.StreamSaveFile(file, TargePath, FileName)` | 以字节流方式异步保存文件到目标路径 | `file` 源文件,`TargePath` 目标目录,`FileName` 保存的文件名 |
|
||||
|
||||
**二进制文件类型 (`BinFileType`):**
|
||||
|
||||
| 枚举值 | 文件头标识 |
|
||||
|-------|----------------|
|
||||
| `ELF` | `7F 45 4C 46` |
|
||||
| `PE` | `4D 5A` |
|
||||
|
||||
```java
|
||||
import top.gtb520.java.gnu.java.utils.library.utils.file.CreateFile;
|
||||
import top.gtb520.java.gnu.java.utils.library.utils.file.CreateFile.BinFileType;
|
||||
import java.io.File;
|
||||
import java.nio.file.Path;
|
||||
|
||||
// 创建普通空白文件
|
||||
File plainFile = CreateFile.NewFile("/path/to/file.txt", false, null);
|
||||
|
||||
// 创建 ELF 二进制文件(自动写入 ELF 文件头)
|
||||
File elfFile = CreateFile.NewFile("/path/to/program", true, BinFileType.ELF);
|
||||
|
||||
// 创建 PE 二进制文件(自动写入 MZ 文件头)
|
||||
File peFile = CreateFile.NewFile("/path/to/app.exe", true, BinFileType.PE);
|
||||
|
||||
// 异步字节流保存文件
|
||||
boolean success = CreateFile.StreamSaveFile(sourceFile, Path.of("/path/to/dest"), "output.bin");
|
||||
```
|
||||
|
||||
### 4. 文件加密/解密 (`file/EncryptionAndDecryption`)
|
||||
|
||||
支持 **AES**、**DES** 对称加密,加密后覆盖原文件,密钥单独保存到指定目录。解密时从密钥文件读取密钥,解密后覆盖还原原文件。
|
||||
|
||||
| 方法 | 说明 | 参数 |
|
||||
|----------------------------------------------------------------|--------------------------|-----------------------------------------------|
|
||||
| `EncryptionAndDecryption.EncryptionFile(file, type, keyPath)` | 异步加密文件,覆盖原文件,密钥保存到 keyPath | `file` 文件,`type` 加密类型,`keyPath` 密钥目录路径 |
|
||||
| `EncryptionAndDecryption.DecryptionFile(file, type, keyfile)` | 异步解密文件,覆盖还原原文件 | `file` 加密文件,`type` 加密类型,`keyfile` 密钥文件 |
|
||||
|
||||
**加密类型 (`EncryptionType`):**
|
||||
|
||||
| 枚举值 | 算法 | 密钥长度 |
|
||||
|-------|---------------------|---------|
|
||||
| `AES` | AES/ECB/PKCS5Padding | 128 bit |
|
||||
| `DES` | DES/ECB/PKCS5Padding | 56 bit |
|
||||
| `RSA` | AES(对称替代) | 128 bit |
|
||||
|
||||
> 加密后密钥文件命名为 `原文件名.key`,保存在 `keyPath` 目录下。
|
||||
> 加密/解密均覆盖写回原文件,不添加额外后缀。
|
||||
