TripleDES with weak keys

[Jeronimo Bertran]

I need to encrypt data using a weak key (all 0s) that is being supplied but
I get an exception because the key is weak.

Is there any way to make the TripleDES class encrypt with such a key?

Thanks

Hello,

In 128-bit mode, if the first 64 bits are the same as the last 64 bits, the
key is weak. Attempting to set a weak key results in a
CryptographicException.So you may consider other way other than TripleDES.
