Encrypting a File or Stream with DES java

Encrypting a File or Stream with DES This example implements a class for encrypting and decrypting files or streams using DES. The class is created with a key and can be used repeatedly to encrypt and decrypt streams using that key. public class DesEncrypter { Cipher ecipher; Cipher dcipher; DesEncrypter(SecretKey key) { // Create an 8-byte initialization vector byte[] iv = new byte[]{ (byte) 0x8E , 0x12 , 0x39 , (byte) 0x9C , 0x07 , 0x72 , 0x6F , 0x5A }; AlgorithmParameterSpec paramSpec = new IvParameterSpec(iv); try { ecipher = Cipher.getInstance("DES/CBC/PKCS5Padding"); dcipher = Cipher.getInstance("DES/CBC/PKCS5Padding"); // CBC requires an initialization vector ecipher.init(Cipher.ENCRYPT_MODE, key, paramSpec); dcipher.init(Cipher.DECRYPT_MODE, key, paramSpec); } catch (java.security.InvalidAlgorithmPa...
