Extract RSA key value from XmlString

Question

Hi all!

I need to extract the RSA key values ( Modulus, exponent etc... ) from String generated by RSA->ToXmlString() method.

Could somebody help me? 

Thanks! 



  

Answer 1

RSA::FromXmlString() looks promising.

Answer 2

Ok, but this method is good to an System.Security.Cryptography.RSA object, while i would extract key values in a byte array, for example, but without xml tags.

for example, i have  this node in my xmlString

<Modulus>zjFmn/hT8J3wZqW5IhU4aQggHtqZmL+OpWO1HCgo4x38HAbRXrrzXH2d3FA0AOSipfluDh1vSq/FMC/Kvm//xw==</Modulus>

and i wont the modules value only
zjFmn/hT8J3wZqW5IhU4aQggHtqZmL+OpWO1HCgo4x38HAbRXrrzXH2d3FA0AOSipfluDh1vSq/FMC/Kvm//xw==

Thanks!

 

Answer 3

You probably want to use RSACryptoServiceProvider instead.  Its ExportParameters() method gives you direct access to the Modulus value.
