I evaluate xceed got from another system only the exponent and modulo as RSA public key.How can I convert them that I can use it with xceed.
myString = ????(exponent, modulo)xRSA.PrivateKey = myString
Other questions: which format has the private key? Is it ASN.1/DER?
Best regards and thanks in advance,David

We do not support initializing the keys using the various components. However, our key “blob” format is indeed formed using ASN.1 and DER as prescribed by the RSA PKCS #1, so you could generate the blob yourself if you have enough time and patience.
Here are some links that may guide you in this :
