[RESOLVED] Encryption problem

[xor83]

I have one encryption method which encrypt simple text to unreadable format but there is one problem with this encryption method if i run that method twice it will decrypt the encrypted string. Is there any way so that i can know if string is already encrypted?

Just a thought...I don't know how you are doing it. Add a 1 or 0 to the front of the Encrypted text to check and ignore it when flipping back and forth.

EncryptedText = 1 & EncryptedText

If mid(EncryptedText,1,1) = 1 then Encrypted else not Encrypted

Then get the text Mid(EncryptedText,2,Len(EncryptedText -1))

Soemthing like that anyway.

That's how XOr encrytion is supposed to work. Might as well determine how come it was called twice, or why it was called for decryption when encryption was intended.

In short, check processing flow. It's a logical error.

Thanks for your rpl

Can you tell me more about XOr encryption?
