Hi
This looks like a great toolkit with some very nice documentation and examples but I cant seem to find an example to fit my requirements.
I would like to select one of a range of PKI X509 certificates in "My Store" as required and use either the public or private key to decrypt / encrypt some data the user has filled in on screen or been sent ( not file based )
I have been looking at the ElRSAKeyMaterial and ElRSAPublicKeyCrypto classes.
Can you point me in the right direction / set of classes I should be considering please ?

regards
Adrian

Hi. There is a property ElX509Certificate.KeyMaterial. But you are advised to use higher level cryptography, like PKCS#7 (please read the how-to at http://www.eldos.com/documentation/sbb/documentation/ref_howto_pki_pkcs7_encrypt.html)

Hi - Thanks for you quick response and informative link - I think I had seen this example but was concerned that by definition the PKCS#7 format would add additional data to my encrypted string which I was trying to avoid.
Are there any examples of ElX509Certificate.KeyMaterial usage for my purpose
Regards
Adrian
