First, they're not "encryption libraries", they're TLS libraries. They do much
more than just encryption.
Then: this looks like an area for improvement in the mbedTLS backend as I
don't think there's any good reason for this struct to be this big. If you
roll up your sleeves and get to work I expect it could be taken down
significantly.
To compare, the wolfSSL ssl_backend_data struct is 16 bytes.
I'm biased (as this is a product by my employer) but wolfSSL is a way better
choice than mbedTLS almost every time, for this and other reasons.
