An AES key is a random bitstring of the right length.

I am doing AES Key Generation in c# and passing the key generated for AES 128 bit Encryption. The case is while generating the key I am getting byte length as 16 while the key string length is getting higher than 16. AES 256 file encryption key mistake. How does an AES work?

• 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:

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.

Creating the AES key

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.
