JNI的包装到的OpenSSL AES_ENCRYPT - 不工作

我正在尝试使用android open ssl加密和解密文件 . 下面分享JNI包装器的相同内容 .

JNIEXPORT jbyteArray JNICALL
Java_com_example_MainActivity_AESencrypt( JNIEnv* env, jobject thiz, jint 
length, jbyteArray jarrByte)
{
unsigned char plaintext[AES_BLOCK_SIZE * 4];
unsigned char ciphertext[AES_BLOCK_SIZE * 4];
unsigned char checktext[AES_BLOCK_SIZE * 4];
const unsigned char userKey[AES_BLOCK_SIZE * 4] = "123456";
const int bits = 128;
AES_KEY keyin = { { 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1, 0,
                    0,
                    0, 0, 0, 1, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 1, 1, 0, 0, 0, 0, 0, 0, 0,
                    0, 0, 0, 1, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 1, 1, 0, 0, }, 12 };
AES_KEY *key = &keyin;
jbyte* pJbyte = env->GetByteArrayElements(jarrByte, NULL);
if(pJbyte!=NULL){
   memcpy(plaintext, pJbyte, length);
   env->ReleaseByteArrayElements(jarrByte, pJbyte, JNI_ABORT);
}
unsigned char* beforeEncrypt = &plaintext[0];
unsigned char* afterEncrypt = &ciphertext[0];
AES_set_encrypt_key(userKey, bits, key);
AES_encrypt(beforeEncrypt, afterEncrypt, key);
jbyteArray jarrRet = env->NewByteArray(strlen((char*) ciphertext));
env->SetByteArrayRegion(jarrRet, 0, strlen((char*) ciphertext), (jbyte *) ciphertext);
return jarrRet;
}

JNIEXPORT jbyteArray JNICALL
Java_com_example_MainActivity_AESdecrypt( JNIEnv* env, jobject thiz, jint 
length, jbyteArray jarrByte)
{
 unsigned char encryptText[AES_BLOCK_SIZE * 4];
 unsigned char ciphertext[AES_BLOCK_SIZE * 4];
 unsigned char checktext[AES_BLOCK_SIZE * 4];
 const unsigned char userKey[AES_BLOCK_SIZE * 4] = "123456";
 const int bits = 128;
AES_KEY keyin = { { 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1, 0,
                    0,
                    0, 0, 0, 1, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 1, 1, 0, 0, 0, 0, 0, 0, 0,
                    0, 0, 0, 1, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 1, 1, 0, 0, }, 12 };
AES_KEY *key = &keyin;
jbyte* pJbyte = env->GetByteArrayElements(jarrByte, NULL);
if(pJbyte!=NULL){
    memcpy(encryptText, pJbyte, length);
    env->ReleaseByteArrayElements(jarrByte, pJbyte, JNI_ABORT);
}

unsigned char* beforeDecrypt = &encryptText[0];
unsigned char* afterDecrypt = &ciphertext[0];
AES_set_decrypt_key(userKey, bits, key);
AES_decrypt(beforeDecrypt, afterDecrypt, key);

jbyteArray jarrRet = env->NewByteArray(strlen((char*) ciphertext));
env->SetByteArrayRegion(jarrRet, 0, strlen((char*) ciphertext), (jbyte *) ciphertext);
return jarrRet;
}

我正在调用JNI方法如下 .

Mainactivity.java :
   public void jni_encryption_and_decryption {

                    // reads the file and converts into bytes 
                    plainTextBytes = getBytesFromInputFile(); 
                    len = plainTextBytes.length;

                    // encrypts the plain text and returns the encrypted bytes
                    byte[] encryptedByte = AESencrypt(len, plainTextBytes);
                    String encryptString = new String(encryptedByte);
                    encrypt.setText(encryptString);

                    len = encryptedByte.length;
                    // decrypts encrypted bytes and returns the decrypted bytes
                    decryptedByte = AESdecrypt(len, encryptedByte);
                    String decryptString = new String(decryptedByte);
                    decrypt.setText(decryptString);
      }

加密工作正常，但在解密时，垃圾即将到来，如果文件包含更多的纯文本，它也不会解密完整的纯文本 .

Input from File: 这是一个android openssl加密和解密演示

Encryption Text: UZ L\n c a [ ܰ h 0_

Decryption Text: 这是一个andro 0_ ！

我还在加密前后共享字节 . 直到第15个索引字节是相同的 . 之后发现字节不一样 .

Jni Wrapper有什么问题？我错过了什么吗？请帮忙 .

JNIEXPORT jbyteArray JNICALL 
Java_com_example_MainActivity_doEncryption(jbyteArray data_plaintext, int 
plaintext_len, jbyteArray data_key,
        jbyteArray data_iv, jbyteArray data_ciphertext)
{
unsigned char* key = (unsigned char*) data_key;
unsigned char* iv = (unsigned char*) data_iv;
unsigned char* plaintext =  (unsigned char*) data_plaintext;
unsigned char* ciphertext =  (unsigned char*) data_ciphertext;
EVP_CIPHER_CTX *ctx;

int len;

int ciphertext_len;

/* Create and initialise the context */
if(!(ctx = EVP_CIPHER_CTX_new())){
    ERR_print_errors_fp(stderr);
    abort();
}


/* Initialise the encryption operation. IMPORTANT - ensure you use a key
 * and IV size appropriate for your cipher
 * In this example we are using 256 bit AES (i.e. a 256 bit key). The
 * IV size for *most* modes is the same as the block size. For AES this
 * is 128 bits */
if(1 != EVP_EncryptInit_ex(ctx, EVP_aes_256_cbc(), NULL, key, iv)){
    ERR_print_errors_fp(stderr);
    abort();
}

/* Provide the message to be encrypted, and obtain the encrypted output.
 * EVP_EncryptUpdate can be called multiple times if necessary
 */
if(1 != EVP_EncryptUpdate(ctx, ciphertext, &len, plaintext, plaintext_len)){
    ERR_print_errors_fp(stderr);
    abort();
}
ciphertext_len = len;

/* Finalise the encryption. Further ciphertext bytes may be written at
 * this stage.
 */
if(1 != EVP_EncryptFinal_ex(ctx, ciphertext + len, &len)){
    ERR_print_errors_fp(stderr);
    abort();
}
ciphertext_len += len;

/* Clean up */
EVP_CIPHER_CTX_free(ctx);
jbyteArray  ciphertext_copy = (jbyteArray ) ciphertext;

return ciphertext_copy;
}
