Someone correct me if I'm wrong, but I'm afraid it's not likely that
openssl will work for your use case. You might try wolfSSL, polarSSL, or
some purpose-built embedded encryption librarly. If you have a specific
cryptographic operation to achieve, it might help point you in the right
direction.

You didn't get a reply in 24 hours from an open source mailing list?  A little 
patience.

OpenSSL uses malloc, etc.  Look at crypto/mem.c and (in 1.1.0 and master) the 
manpage for CRYPTO_malloc.

Nothing like that exists.

Ping !!!

Upon code-browsing, I am beginning to feel that OpenSSL uses
program-buffer, which is used for malloc/free.
Am I right?

If yes, is there a place where the maximum-size of "in-program-buffer-heap"
is defined?

[openssl-users] Code-Architecture questions while compiling OpenSSL for STM32-processors

[Ajay Garg]

Hi All.

I wish to compile openssl libraries for a STM32-processor (which would then
be linked statically with our application-framework code).


Now. I believe that OpenSSL uses tonnes of "malloc"s and "free"s. But for
bare-metal-systems (without any formal OSes), we generally don't have any
heap-memory.

So, what is the protocol for compiling OpenSSL for such systems?
I am sorry, but this is the first time I would be compiling for a non-OS
entity.


Will be thankful for inputs.


Thanks and Regards,
Ajay
