Encrypt and decrypt files and directories using zip4j

Talk less, look directly at the tool class:

 PackageCom.ilucky.zip4j.util;ImportJava.io.File;ImportNet.lingala.zip4j.core.ZipFile;ImportNet.lingala.zip4j.exception.ZipException;ImportNet.lingala.zip4j.model.ZipParameters;Importnet.lingala.zip4j.util.Zip4jConstants;/** * @author iluckysi * @since 20150723 * * Public  class zip4jutil {    PrivateString Srcpath;PrivateString Dstpath;PrivateString Password ="123456"; PublicStringGetsrcpath() {returnSrcpath; } Public void Setsrcpath(String Srcpath) { This. Srcpath = Srcpath; } PublicStringGetdstpath() {returnDstpath; } Public void Setdstpath(String Dstpath) { This. Dstpath = Dstpath; } PublicStringGetPassword() {returnPassword } Public void SetPassword(String password) { This. Password = password; }/** * Encryption * supports encrypting all files in a file or directory.     * 1. A file: D:\\test\\src.zip. * 2 a directory: D:\\TEST\\SRC * @return boolean */     Public Boolean Encrypt() {Try{if(!NewFile (Srcpath). Exists ()) {System.out.println ("Source path does not exist"+srcpath);return false; } zipparameters parameters =NewZipparameters (); Parameters.setencryptfiles (true);              Parameters.setencryptionmethod (Zip4jconstants.enc_method_aes);              Parameters.setaeskeystrength (zip4jconstants.aes_strength_256);              Parameters.setpassword (Password.tochararray ()); File Srcfile =NewFile (Srcpath); ZipFile destfile =NewZipFile (Dstpath);if(Srcfile.isdirectory ())              {Destfile.addfolder (srcfile, parameters); }Else{destfile.addfile (srcfile, parameters); } System.out.println ("Successfully encrypted files");return true; }Catch(Exception e) {System.out.println ("Encrypting file has an exception:"+E);return false; }    }/** * Decryption * Supports extracting an encrypted file under a specified directory. * @return boolean */     Public Boolean Decrypt() {Try{if(!NewFile (Srcpath). Exists ()) {System.out.println ("Source path does not exist"+srcpath);return false; } ZipFile srcfile =NewZipFile (Srcpath); Srcfile.setfilenamecharset ("GBK");               Srcfile.setpassword (Password.tochararray ());             Srcfile.extractall (Dstpath); System.out.println ("Successfully decrypted file");return true; }Catch(Zipexception e) {System.out.println ("The decryption file has an exception:"+E);return false; }    }}

Then look at the test class:

 PackageCom.ilucky.zip4j.util;/** * @author iluckysi * @since 20150723 * * Public  class maintest {     Public Static void Main(string[] args) {//encryption.Zip4jutil Zip4jutil =NewZip4jutil (); Zip4jutil.setsrcpath ("D:\\test\\src.zip"); Zip4jutil.setdstpath ("D:\\test\\dst.zip"); Zip4jutil.setpassword ("123"); Zip4jutil.encrypt ();//decryption.Zip4jutil.setsrcpath ("D:\\test\\dst.zip"); Zip4jutil.setdstpath ("d:\\test\\"); Zip4jutil.setpassword ("123");//zip4jutil.decrypt ();}}

Finally look at the Pom file:

<dependency>        <groupId>net.lingala.zip4j</groupId>        <artifactId>zip4j</artifactId>        <version>1.3.2</version>    </dependency>
