I need to create a internal AES/Base64 encrypt system for my application. I mean , I don't want to have any side dll for my exe like openssl library.

I found this threads :

But they wasn't what I need , I searched and I found nothing.

What I need exactly is like this site : https://aesencryption.net/

  1. First an AES encryption with a key at 256bit mode
  2. Next convert it to Base64 ( a Result of encryption in base64 in aesencryption.net )
  3. And a decrypt system to get the first string from encrypted result.

In this thread the key has to be 32 lenght but in the aesencryption.net it can be everything .

Can you please guide me how can I create a system like aesencryption.net site ?

    You can compile OpenSSL as a static library. Please do not plan on writing your own AES implemention. http://www.moserware.com/2009/09/stick-figure-guide-to-advanced.html (See the slide labelled "Foot-shooting prevention agreement".) – Martin Bonner supports Monica May 02 '18 at 12:36

  • @SamuelHardson - well I've voted to close as too broad. Please [edit] your question to clarify you want recommendations for suitable libraries, and we can close it as being "off-topic: requests for library". Sorry, but SO had rules about what is on-topic here, and this question isn't. – Martin Bonner supports Monica May 02 '18 at 12:38
  • @MartinBonner my bad , I respect the community . please do what is right. – Samuel Hardson May 02 '18 at 12:48
