Re: TLS handshake speeds: RSA is faster than ECC!?

The 'RSA' peripheral actually is a more general modular math module. If memory serves, this is what ECC uses as well. ah yeah, I just saw it is basically a bignum accelerator. Thank you! Well, then I would say it would be great to see "enhanced hw crypto performance" on the ESP32 v2 roadmap ;) Best...

Re: TLS handshake speeds: RSA is faster than ECC!?

As far as I can see you have no ECC accelerator registers somewhere in your SDK:
https://github.com/espressif/esp-idf/bl ... ypto_reg.h

So I expect ECC is completely done in software?

Re: TLS handshake speeds: RSA is faster than ECC!?

Is it possible that currently only RSA is handled using hardware acceleration but no ECC? I can find some RSA crypto stuff in components/mbedtls/port/esp_bignum.c but I cannot find any ECC stuff. Even in the ESP32 Technical Reference there is no chapter about the ECC accelerator. Dear Espressif deve...

TLS handshake speeds: RSA is faster than ECC!?

Hi, I am currently working on a TLS secured webserver running on esp32. To get started I have used the example 10_openssl_server. When I execute a GET request using the provided 2048 bit RSA key and certificate it takes about 1.6 seconds to complete the request. Most of the time is used for handshak...

Re: Problems connecting to WiFi

no, it's just about checking out the esp-idf master and then doing a git submodule update to checkout the referenced versions.
I am not trying to checkout all master branches in the submodules!

I thought so, too. But when you checkout master again it is still working, isn't it?

Deti
For me it worked after checking out tag "v1.0".

Code: Select all

git fetch --all --tags --prune
git checkout tag/v1.0

Re: Problems connecting to WiFi

Deti,
maybe this helps:

go into your esp-idf directory and execute "git pull origin master && git checkout master && git submodule update"
Then go to your project and do a "make clean".
Then compile.

Does it help?

Best,
Malte

Re: Problems connecting to WiFi

OK, it's working now. I do not know what has happened. I have cleaned, checked out older versions from git, updated submodules, cleaned, built, checkout master again, cleaned, built, everything multiple times and now it works. I am sorry, I cannot reproduce the error. I have changed nothing on my Wi...
