Stream Cipher
I want to encrypt data use two layer cipher as follow,but it seems not work, why and how, thanksï¼?
encrypt partï¼?
Cipher cf1 = Cipher.getInstance(ciphAlg1);
cf1.init(Cipher.ENCRYPT_MODE, key1, paramSpec);
Cipher cf2 = Cipher.getInstance(ciphAlg2);
cf2.init(Cipher.ENCRYPT_MODE, key2, paramSpec2);
FileInputStream fis = new FileInputStream(inputFile);
FileOutputStream fos = new FileOutputStream(outputFile);
CipherOutputStream cos1 = new CipherOutputStream(fos, cf1);
CipherOutputStream cos2 = new CipherOutputStream(cos1, cf2);
decrypt partï¼?
Cipher cf1 = Cipher.getInstance(ciphAlg1);
cf1.init(Cipher.DECRYPT_MODE, key1, paramSpec);
Cipher cf2 = Cipher.getInstance(ciphAlg2);
cf2.init(Cipher.DECRYPT_MODE, key2, paramSpec2);
FileInputStream fis = new FileInputStream(inputFile);
FileOutputStream fos = new FileOutputStream(outputFile);
CipherOutputStream cos1 = new CipherOutputStream(fos, cf2);
CipherOutputStream cos2 = new CipherOutputStream(cos1, cf1);
One layer work well, but the double...
