Arduino (using Arduino IDE or PlatformIO) and ESP-IDF (using Espressif IoT Development Framework or PlatformIO) compatible library for encrypting and decrypting messages to be sent over protocols like ESP-NOW, 802.15.4 and similar.

Add the following to lib_deps:

   Johboh/GCMEncryption

In your existing idf_component.yml or in a new idf_component.yml in your src or main folder:

dependencies:
  johboh/gcmencryption:
    version: ">=0.5.2"

Search for GCMEncryption by johboh in the library manager.

In your existing idf_component.yml or in a new idf_component.yml next to your main folder:

dependencies:
  johboh/gcmencryption:
    version: ">=0.5.2"

Search for GCMEncryption by johboh in the library manager. See note about version above.

• Using Arduino IDE/CLI or Platform IO Arduino
