An ESP32/ESP8266 library for Arduino IDE to wrap AES encryption with Base64 support. This project is originally based on AESLib by kakopappa. This fork actually works, will be maintained at least for a while, and provides optimised methods that do not require using Arduino's flawed String objects (even though those are still in examples).
AESLib provides convenience methods for encrypting data to byte arrays and Strings, with optional additional base64 encoding to return strings instead of bare data.
Since ESP8266 Arduino Core 2.6.2 is already out, this might be updated to use AES implementation from BearSSL (to save more RAM in larger projects). But it would loose compatibility with AVR so this is a NO for now.
- ESP8266 (OK)
- Arduino Uno (OK)
- Arduino Mega 2560 (OK)
2.2.1 - Major decryption fix
2.2.0 - Improved examples
2.1.8 - Improved examples
2.0.8 - Input buffer reuse optimizations by (via @ElMohamed)
2.0.7 – Applied const specifiers throughout the library (via @kenkendk)
2.0.6 – Added Travis CI unit and platform tests; getrnd() is mocked on platforms without time() or millis() is used instead
2.0.5 – Restored backwards compatibility with AVR; updated Simple and Medium examples
2.0.3 – Added unit tests; thus fixed getrnd()
2.0.1 - Cleaner implementation, dropping Arduino framework in favour of testability and portability
2.0 - Fixed padding, added parametrisation (via @kavers1), restored Arduino compatibility, memory optimisations
1.0.5 - Fixed generating random IV; fixed #include directive filename case
1.0.4 - Fixed simple example
1.0.3 - Fixed padding (after encoding, not before)
See examples.
Requires node.js and npm.
Enter the nodejs folder in Terminal and install required npm packages with npm install . command.
You can run the example with node index.js as you know it, and then dig into the source code to adjust for your purposes.
See node/index.js for implementation details.
This is an AES library for the ESP8266, based on tzikis's AES library for Arduino, was previously here. Tzikis library was based on scottmac's library, which was previously here, but now seems to be removed. The library is code-wise compatible with Arduino AVR, but it requires more RAM than it is usually available on Arduino boards.
