Inputs To The API

1. The password for encryption.
2. The InputStream that need to be encrypted/decrypted.
3. The OutputStream where the encrypted/decrypted data need to be written.

Usecase: Encryption

1. Use password "mypassword"
2. File to be encrypted: "myfile.jpg" in the current directory
3. Encrypted output file: "myfile.jpg.wiz" in the current directory

Encryption, the code

The Exception handling code is not shown. Please refer to JavaDoc.

 import org.wiztools.wizcrypt.CipherKey;
 import org.wiztools.wizcrypt.CipherKeyGen;
 import org.wiztools.wizcrypt.WizCrypt;

 import java.io.*;

 // Get the CipherKey object by giving the password:
 String password = "mypassword";
 CipherKey ck = CipherKeyGen.getCipherKeyForEncrypt(password);

 // Get the InputStream & OutputStream
 InputStream is = new FileInputStream("myfile.jpg");
 OutputStream os = new FileOutputStream("myfile.jpg.wiz");

 // Encrypt!
 WizCrypt.encrypt(is, os, ck);
 

Usecase: Decryption

1. Use password "mypassword"
2. File to be decrypted: "myfile.jpg.wiz" in the current directory
3. Decrypted output file: "myfile.jpg" in the current directory

Decryption, the code

 import org.wiztools.wizcrypt.CipherKey;
 import org.wiztools.wizcrypt.CipherKeyGen;
 import org.wiztools.wizcrypt.WizCrypt;

 import java.io.*;

 // Get the CipherKey object by giving the password:
 String password = "mypassword";
 CipherKey ck = CipherKeyGen.getCipherKeyForDecrypt(password);

 // Get the InputStream & OutputStream
 InputStream is = new FileInputStream("myfile.jpg.wiz");
 OutputStream os = new FileOutputStream("myfile.jpg");

 // Decrypt!
 WizCrypt.decrypt(is, os, ck);
 

Note: CipherKey generation for both encryption and decryption call different methods.

Download

For using the API, download wizcrypt-XX.jar. The only other dependency WizCrypt has, Commons-cli is not needed when the API is used. So, if you are planning to use the API and not WizCrypt as a tool, download wizcrypt-XX.jar and not wizcrypt-XX-jar-with-dependencies.jar.
