X.509 pharo smalltalk certificate operations

I am very new to smalltalk. I installed Pharo 5.0 and use a standard image.

I want to create / read x.509 certs in Smalltalk. I searched and found ZdcPluginSSLSession (which uses SqueakSSL, which in turn uses ssleay32.dll / libeay.dll). I understand that Zodiac / Zinc can be used to create SSL sessions with certificates.

Can anyone tell me how to get started with smalltalk certificates. I want to perform operations with certificates, for example, create / analyze / verify, etc. Am I using ssleay32.dll instead? Where can I get good documents for FFI to be used with Pharo 5.0?

Thanks in advance.

You can go your own route using FFI or use only the smalltalk method. For the latter, you can download the project from

http://smalltalkhub.com/#!/~NorbertHartl/X509

for reading certificates. You can download it by opening the playing field and doing:

Metacello new
  configuration: 'X509';
  version: #development;
  repository: 'http://smalltalkhub.com/mc/NorbertHartl/X509/main';
  load.

Implementation there can be used with

X509 readCertificateFromPEM: '/path/to/pem/file.pem' asFileReference readStream

The implementation of the X509 is quite simple and gives you an idea of ​​how to work with the included ASN.1 package. If you have any questions, please contact me directly. I really want to help with this.
