I am trying to make an java application to compress file and folders in .zip format..
i want to add additional functionality of adding password to a zip file,for this i want to use aes-256 algorithm but i am stuck with this,i can't figure it out.
if i apply aes algorithm to file and add password where this password get stored??in the file crc or in some file data field,
Do i need to use an API for this or else this could be done without api and by creating my own java program??
