Encryption/Decryption in nodemcu via Arduino IDE

I am new in nodemcu and I want to know which library I have to install so that I can implement AES algorithm or any encryption algorithm using nodemcu via Arduino IDE.

Please give me your suggestions ASAP.

The last I heard from you on this topic in your previous thread:
http://forum.arduino.cc/index.php?topic=544041
you already had a library but hadn't figured out how to install it. I provided you installation instructions but never heard anything more on the subject.

So what's the point in people suggesting a library if you can't even install it. Don't you think it would be a good idea to first learn the basic and essential skill of installing a library before moving on to the advanced task of implementing an encryption algorithm?

Actually, I am getting this error after installing the library.

fatal error: avr/pgmspace.h: No such file or directory

#include <avr/pgmspace.h>

^

compilation terminated.

Error compiling for board NodeMCU 1.0 (ESP-12E Module).

that's why I have to post this thing again. sorry for your inconvenience

Then why didn't you just say that?

When you encounter an error you'll see a button on the right side of the orange bar "Copy error messages". Click that button. Paste the error in a message here USING CODE TAGS (</> button on the toolbar).
