Encrypting, decrypting - any better idea how to work with file?

[Gapple]

Thanks again for your suggestions. Before going too far, I experimented with the demo code of Rijndeal and DES. I substituted the line 41. test="01234567890abcdefg" with a string using French accents "Hélène est très belle" only to find the MSG did not return the accented characters. Further, I wrote the same string (str) to the TextBox1 of the form1 with the same result.

Sorry, I'm new to this. Could you explain how to work around this apparent UTF-8 incompatibility ?

Thanks for your patience.

Use DecryptString which is commented out in the demos. I've just noticed that there is a typo in the DecryptString line, it omits the buffer parameter. It should read

str = Des.DecryptString(code())

EDIT:- Note that the problem is one of display, not a decryption problem. Encrypt string knows about UTF8 and so does DecryptString. Just displaying the decoded UTF8 bytes as characters looks wrong but is in fact correct and also shows the string padding referred to in the comments.
