I got a peoblem with my JDK and I can't run the the code so can i have the output for these
three method using JNI :
original character array
encrypted character array
decrypted character array
java cod:
public class CaesarCipher
Load the shared library
static
System.loadLibraryCaesarCipherLib;
Native method to create a character array from user input
public native char createCharArrayString input;
Native method to perform Caesar Cipher encryption
public native char encryptchar original, int key;
Native method to perform Caesar Cipher decryption
public native char decryptchar encrypted, int key;
Main method for testing
public static void mainString args
CaesarCipher cipher new CaesarCipher;
Test createCharArray
char originalArray cipher.createCharArrayHelloWorld;
System.out.printlnOriginal Array: new StringoriginalArray;
Test encrypt
int encryptionKey ;
char encryptedArray cipher.encryptoriginalArray encryptionKey;
System.out.printlnEncrypted Array: new StringencryptedArray;
Test decrypt
int decryptionKey ;
char decryptedArray cipher.decryptencryptedArray decryptionKey;
System.out.printlnDecrypted Array: new StringdecryptedArray;
c code:
#include
JNIEXPORT jcharArray JNICALL JavaCaesarCiphercreateCharArrayJNIEnv env jobject obj, jstring input
const char inputStr envGetStringUTFCharsenv input, ;
Create a character array
int length envGetStringUTFLengthenv input;
jcharArray charArray envNewCharArrayenv length;
jchar chars envGetCharArrayElementsenv charArray, NULL;
Copy the input string to the character array
for int i ; i length; i
charsi inputStri;
Release resources
envReleaseStringUTFCharsenv input, inputStr;
envReleaseCharArrayElementsenv charArray, chars, ;
return charArray;
JNIEXPORT jcharArray JNICALL JavaCaesarCipherencryptJNIEnv env jobject obj, jcharArray original, jint key
Perform Caesar Cipher encryption
return original; Placeholder, replace with actual implementation
JNIEXPORT jcharArray JNICALL JavaCaesarCipherdecryptJNIEnv env jobject obj, jcharArray encrypted, jint key
Perform Caesar Cipher decryption
return encrypted; Placeholder, replace with actual implementation
