It seems that 32 bytes (256 bits) is the maximum key size. If so, is there a list of elliptic curves that will work with keys of this size?

Thank you for your answer, Jocelyn.I had suspected the key was always 256 bits or smaller, but I am still new to AES and learning.Regarding the XCUBE Cryptolib: I believe I have this installed (it is in a "Middlewares" folder in my project). Is the ...

How do I add the CMOX crypto stack to an existing project?

Is the AES peripheral on the STM32L4xx MCUs able to handle key sizes larger than 32 bytes? Is there a list of elliptic curves that will work with a 32 byte key?
