I have opened bug for this issue (bug# 76483).
Please see attached file for source code.
To Compile : mcs TestEncryption.cs
To Run : mono TestEncryption.exe
System.Security.Cryptography.CryptographicException: IV length cannot be
larger than block size
in <0x000e0> System.Security.Cryptography.SymmetricAlgorithm:set_IV
tor (System.Byte rgbKey, System.Byte rgbIV)
in <0x0013d> TestEncryption.TestEncryption:Main (System.String args)

Sorry I can't help you without more details.
Please open a bug report at http://bugzilla.ximian.com and include a
small source code sample that reproduce the problem. Don't forget to
indicate which version of Mono you are using and on which platform.

You can access the documentation from http://www.mono-project.com
Click on "manuals and docs" (icon on top right) then navigate the tree
view to get to the desired class documentation.
Here's a direct link to the TripleDES class

System.Security.Cryptography implements the same classes (i.e. same
features/same limites) as MS base class library.
Mono.Security.Cryptography offer extra classes (i.e. not available on
the MS framework).
