I am trying to sign some data and generate a CMS (Cryptographic Message Syntax)
using a certificate in PKCS#12 format and the following name spaces:
System.Security.Cryptography, System.Security.Cryptography.Pkcs,
System.Security.Cryptography.X509Certificates.

When I run the application on DOT NET 3.5, I obtain the CMS but on MONO 2.6.7
and 2.10.1 the application thrown an Cryptographic Exception:

Unhandled Exception: System.Security.Cryptography.CryptographicException: 
  at System.Security.Cryptography.Pkcs.SignedCms.ComputeSignature
(System.Security.Cryptography.Pkcs.CmsSigner signer) [0x00000] in <filename
unknown>:0 
  at TestPkcs7Signature.Pkcs7Signature.Main (System.String[] args) [0x00000] in
<filename unknown>:0




Reproducible: Always

Steps to Reproduce:
1. Compile: gmcs -r:System,System.Security pkcs7signature.cs
2. Run: mono pkcs7signature.exe

Actual Results:

  at TestPkcs7Signature.Pkcs7Signature.Main (System.String[] args) [0x00000] in
<filename unknown>:0

Expected Results:
