Hi guys...
I'm having some problems to use the DES class to
encrypt things...
When i pass a Key to the CreateEncryptor method of the
DES class, i get
a "System.Security.Cryptography.CryptographicException:
Specified key is not a valid size for this algorithm."
Well this is the Key that i'm using to Criptography the
text: "s2@$vKT,-_0~`L+lo*&^(lo)[*k]<0xb q]>|!^<kjf ]>[<?/1"
is this a weak key..? if it is... what is the rules to
make a "strong" key..?
Thanks in advance...

Hi,
The key of the DESCryptoServiceProvider must be 64 bytes. You can get the
valid key size from the property LegalKeySizes.
I hope this helps. If you have any questions, please reply to this post.
