RSA and cryptography

Is there anyone having crypto algorithms implemented or used a native lib to do so. We are using the Cryptography package and have problems. The code is quite old so we won’t spend time fixing it. We rather interface with a native lib. So I’m asking upfront

thanks,

Norbert

is https://download.libsodium.org/doc/quickstart providing the functions you require? In the past I have used some of the Pharo/Squeak bindings for it.

Have you tried ParrotTalk ? But I think it depends on cryptography (?).

Maybe better would be NaCl bindings but havent tried and it seems quite old:

I don’t think so. We use RSA public key validation. It does not seem that libsodium supports that.

A binding to libcrypto would be best :)

Hi Norbert,

https://github.com/PierceNg/OpenSSL-Pharo

To load:

Metacello new
baseline: 'OpenSSL';
repository: 'github://PierceNg/OpenSSL-Pharo/src-st';
load.

I'm writing a proper README.md. For now the unit tests show what's there
and how to use. For RSA, see LcEvpPublicKeyTest.

I started this with the goal of writing a Let's Encrypt client. That
goal is now dropped, as there are enough tools out there that make LE
integration easy. I'll wrap more of libcrypto as and when I need them.
Contributions welcome. :-)

Great! Seems exactly what I was looking for. :) I‘ll get back to you when I had the chance to look at it.
