How to use?

Windows

-have g++ and libcrypto++(crypto++) preinstalled and configured
-Run Make.bat
else (if you are having issues with g++ and libcrypto++)
-run make_path.bat, this will create a directory c:\Zenc
-Copy exe from release folder to c:\Zenc and use it.

Linux

Clone the repository and open a terminal in the root and use:

   sudo apt-get install g++
   sudo apt-get install libcryptopp++
   g++ src/Zenc.cpp -std=c++17 -lstdc++fs -lcrypto++ -o /usr/bin/Zenc

NOTE: optional - upx the executable (-9 --lzma) (slight boost in performance)

Encryption modes supported:

1. AES-GCM with 2k tables
2. AES-GCM with 64k tables
3. AES-EAX
4. AES-CBC
5. AES-ECB
6. AES-CTR
7. AES-CFB
8. AES-OFB
9. ChaCha20 (stream cipher)
10. XChaCha20 (stream cipher)

How to use

Zenc [-h or -H/-e/-ed/-d/-dd] [FILE PATH] -m [mode] [-p/-np] [Password in case of using -p] [-t -g]
-h or -H Help Menu
-e    Encrypt a file
-ed   Encrypt a directory
-d    Decrypt a file
-dd   Decrypt a directory
-m    Mode of Encryption / Decryption (gcm2k,gcm64k,eax,cbc,ecb,ctr,cfb,ofb)
-p    Password provided by the user (no limit in length or characters)
-np   Either a .zkey file is created or if -g is mentioned then a password is created
-t    Will encrypt/decrypt the titles and the extention
-g    Will generate a password of the length specified by the user

EXAMPLE COMMANDS:

   1. To open the help book:

          Zenc -h
          Zenc -H
          Zenc

   2. To Encrypt a file: 

          Zenc -e C:\test\test.txt -m gcm2k -p Password123 -t (encrypt with a passwprd)     
          Zenc -e C:\test\test.txt -m gcm2k -p C:\test\test.zkey -t (encrypt with a keyfile)   
          Zenc -e C:\test\test.txt -m gcm2k -np -t (generate a keyfile)
          Zenc -e C:\test\test.txt -m gcm2k -np -t -g (generate a password)

   3. To Encrypt a Directory : 

          Zenc -ed C:\test\ -m gcm2k -p Password123 - t (encrypt with a passwprd)
          Zenc -ed C:\test\ -m gcm2k -p C:\test\test.zkey -t (encrypt with a keyfile)
          Zenc -ed C:\test\ -m gcm2k -np -t (generate a keyfile)
          Zenc -ed C:\test\ -m gcm2k -np -t -g (generate a password)

   4. To Decrypt a file: 

          Zenc -d C:\test\test.txt -m gcm2k -p Password123 -t (decrypt with a passwprd)
          Zenc -d C:\test\test.txt -m gcm2k -p C:\test\test.zkey -t (decrypt with a keyfile)

   5. To Decrypt a Directory : 

          Zenc -dd C:\test\ -m gcm2k -p Password123 -t (decrypt with a passwprd)
          Zenc -dd C:\test\ -m gcm2k -p C:\test\test.zkey -t (decrypt with a keyfile)

NOTE: change Zenc according to your environment.
