Hi. I have little problem. 

What I do to encrypt the file: 

   - Generate AES Key and AES Iv
   - Join AES Key and Iv into one string variable aesKeyAndIv
   - Encrypt aesKeyAndIv variable with RSA Public key 
   - Load file for encryption
   - Encrypt file with AES Key and AES Iv
   - Join encrypted file content with aesKeyAndIv


Decryption:

   - Split encrypted file content and aesKeyAndIv
   - Decrypt aesKeyAndIv using private RSA key
   - split aesKeyAndIv
   - Use AES Key and AES Iv to decrypt encrypted file content


Before I used the ";" splitter when each encrypted data (file content and 
aesKeyAndIv) was encoded using Base64, but after encryption the final 
encrypted file is bigger than original. So I decided to Gzip file content 
when loading for encryption and don't use the Base64 when encrypting data 
(file content and aesKeyAndIv). How could I achieve that, if the files are 
now binary? 
BTW. I need to use FileSource, because it handle big files for me.
