Hi,

I need some help, I have a public key and a private key in PKCS#8 file
created with OpenSSL, my task is to extract the private and the public key
from this file to create a RSA instance and also to be able to export this
RSA object in PKCS#8 format.

I did some research on Internet but I don't find something useful I'm afraid.

Thx for your help,
Best regards Stefan

I manage to find a class in Mono witch is able to do this import export thing.

Namespace : Mono.Security.Cryptography
Class: PKCS8

Best regards,
Stefan

You can Pinvoke using:

Is that an encrypted EncryptedPrivateKeyInfo or an unencrypted PrivateKeyInfo ?

Related, here is a PrivateKeyInfo to CryptoAPI PRIVATEKEYBLOB converter (in Java 2 tho! lol) :
