Encryption

[Nitin]

Happy New Year 05'

My program encryptes text using filestream and DES and stores the encrypted
text in a text file. I want to encrypt any text and store it in access data
base(I need the encrypted text as 'string') and not a text file. Can anyone
help me?.
Thanx

Instead of encrypting to a 'FileStream', you can encrypt to a 'MemoryStream'
and then put the data in a database field as a BLOB:

Herfried,

In my idea is there no DES in your answers

However

Cor,

I didn't post information on DES because I assumed that the OP knows where
to find the DES classes in the .NET Framework:
