Yes, you can encrypt multiple plaintexts with the same key, as you couple AES with a cipher-block mode that allows that. ECB does not allow that. But using AES-CTR or AES-CBC with a counter or an IV randomly generated allows you to encrypt a lot of data under the same key. AES is a symmetric block cipher where a single key is used for both encryption and decryption process. The input and output for the AES algorithm each consist of sequences of 128 bits. The key used in this algorithm consists of 128, 192, or 256 bits. AES operates on 8-bit bytes.
An AES key is a random bitstring of the right length.
- For a 128-bit AES key you need 16 bytes.
- For a 256-bit AES key you need 32 bytes.
If you need to generate your own AES key for encrypting data, you should use a good random source. The strength of the key depends on the unpredictability of the random.
Mbed TLS includes the CTR-DRBG module and an Entropy Collection module to help you with making an AES key generator for your key.
To use the AES generator, you need to have the modules enabled in the config.h files (MBEDTLS_CTR_DRBG_C and MBEDTLS_ENTROPY_C), see How do I configure Mbed TLS.
Include the following headers in your code: Generate machine key iis 10.
Then add the following variable definitions to your code:
The personalization string needs to be unique to your application to add randomness to your random sources.

You need to initialize the entropy pool and the random source and extract data for your key. In this case we generate 32 bytes (256 bits) of random data.

Now you can use the data in key as a 256-bit AES key.
