C# RSA Decryption Issue

Question

I tried encrypting connection string on my machine A . It was successful . I exported the key to some other machine B .It tried to decrypt the web config using that exported key . But it failed saying

    C:\Windows\system32>cd C:\Windows\Microsoft.NET\Framework64\v4.0.30319

C:\Windows\Microsoft.NET\Framework64\v4.0.30319>aspnet_regiis -pi "NewEncryptKey

Not enough storage is available to process this command.

Failed!

What am I missing here ? In my machine B while decrypting I tried

cd C:\Windows\Microsoft.NET\Framework64\v4.0.30319

aspnet_regiis -pi "NewEncryptKey" "C:\Users\abalawan\Desktop\NewStuartCN\encryptkeynew.xml"

aspnet_regiis -pa "NewEncryptKey" "NT AUTHORITY\NETWORK SERVICE"

aspnet_regiis -pdf "connectionStrings" "C:\Users\abalawan\Desktop\NewStuartCN"

. Any help will be much appreciated.

Answer 1

You seem to be using the wrong command ( -pdf instead of -pd ):

aspnet_regiis -pdf "connectionStrings" "C:\Users\abalawan\Desktop\NewStuartCN"

should be

aspnet_regiis -pd "connectionStrings" "C:\Users\abalawan\Desktop\NewStuartCN"
