Pooya1 Active Member Licensed User Jan 20, 2018 #1 Hello My app connect to api for give my product and show their I need send api key to api in each request I used sign key "Certificate fingerprints hash" for api key (exist in signature section) But i search about sign key in google and i understood that hacker can get sign key information So How do i can protect api key looklike other apps in Google Store? Thanks Dige

Or you could take a look at Informatix Pro Bundle which contains a steganography library. Upvote 0

Yes i encrypt it in server and get it in app But for decrypt it,i have to use key for decrypt and i cannot set key in source How do steganography library working? if it is good so i buy it Upvote 0

Oh my god it is very professional I see application signature in your library for encryption I understand that application signature maybe hacked,isn't it? And do you have sample in your bundle if i buy it? Upvote 0
