ESP HTTP Client Example

Adding the private and public keys

For the example to work, we need to add an account using the private and public keys.

The binary data is taken from a 64-byte binary file encapsulating both the private and public keys in binary format. It has been generated using the Unix example available in the repo, using the -n flag.

./unix_example -n

You can then copy private_key.bin into the example's main directory and compile.

⚠️ This is not a safe way to handle keys.

Compilation

ESP-IDF build system

For this example to run, you have to download and install ESP-IDF in a separate directory.

Make sure you have the IDF_PATH environment variable defined, either in your ~/.bashrc or ~/.zshrc, or you can run:

# from ESP-IDF directory
. export.sh

Once setup, go to the example directory (same location of the README you are reading) and run:

# 'flash' if you want to install the firmware on your target
# 'monitor' if you want to open the serial interface and see the logs
idf.py build flash monitor

PlatformIO

Open the directory using PlatformIO and build.
