Hi All,
Is there any possible way to encrypt files more than 1 mb in tizen native app

i am following the below method
1.getting the file contents into a ByteBuffer()

2.encrypting the byte buffer  , but byte buffer is not capable of storing data more than 1 mb . if i give file of size more than 1 mb it is giving E_system Error

Can any one provide solution for this issue
Regards
