java - Encryption and decryption of a audio/video file ...
https://stackoverflow.com/questions/16119028/encryption-and-decryption-of-a-audio-video-file-using-aes128
The accepted answer to this question has some good encryption code that you can use - use KeySpec spec = new PBEKeySpec(password, salt, 64, 128); to reduce the iteration count and to use 128-bit encryption instead of 256-bit encryption. This code also uses Cipher Block Chaining instead of Electronic Codebook, which is much more secure (see this Wikipedia …
java - Audio Encryption Using RSA - Stack Overflow
https://stackoverflow.com/questions/13735104/audio-encryption-using-rsa
using the standard encryption library, encrypt the data using a symmetric algorithm such as AES: see, for example, my tutorial on symmetric/AES encryption in Java; use RSA only as a means of passing to the remote client the (AES etc) key that you used to encrypt the data: again, I've written about using RSA in Java with example code.
AES 256 Encryption in Java - Javatpoint
https://www.javatpoint.com/aes-256-encryption-in-java
In the above Java program, the AESExample class defines two methods, encrypt() that implements the AES-256 encryption algorithm and decrypt() that implements the AES-256 decryption algorithm. And lastly, the driver method gives a call to both the methods and displays the result on the console. In this article, we have discussed the AES 256 encryption algorithm …
Java File Encryption and Decryption Simple Example
https://www.codejava.net/coding/file-encryption-and-decryption-simple-example
Basic Steps. Here are the general steps to encrypt/decrypt a file in Java: Create a Key from a given byte array for a given algorithm. Get an instance of Cipher class for a given algorithm transformation. See document of the Cipher class for more information regarding supported algorithms and transformations.
Data Encryption Standard (DES) Code in Java | by AMIT ...
https://medium.com/@amit28amical/data-encryption-standard-des-code-in-java-4a45ad692bae
DES structure is a Feistel network. Advantage: encryption and decryption differ only in the key schedule. Bitwise initial permutation, then 16 round. The plaintext is …
Encryption and Decryption in Java Cryptography | Veracode
https://www.veracode.com/blog/research/encryption-and-decryption-java-cryptography
Symmetric Encryption Cipher c = Cipher.getInstance ("AES/GCM/PKCS5Padding") ; **Use NoPadding instead of PKCS5Padding. This has been discussed in the Symmetric Encryption section of the Java Crypto Catchup post. You can also refer to the working example discussed in the Java Crypto Libraries post. AES-GCM code example can be referred here.
Java Cryptography - Encrypting Data - Tutorialspoint
https://www.tutorialspoint.com/java_cryptography/java_cryptography_encrypting_data.htm
Follow the steps given below to encrypt given data using Java. Step 1: Create a KeyPairGenerator object The KeyPairGenerator class provides getInstance() method which accepts a String variable representing the required key-generating algorithm and returns a KeyPairGenerator object that generates keys.
Protecting Java Codes: Encrypted Class Loader - Sefik ...
https://sefiks.com/2017/04/04/protecting-java-codes-encrypted-class-loader/
Of course, encryption key should be generated randomly with the following code instead of using static key. KeyGenerator generator = KeyGenerator.getInstance(algorithm); generator.init(128); //generate 128 bit key SecretKey secretKey = generator.generateKey(); byte[] key = secretKey.getEncoded();
