Hi Michael,
Here is a code snippet. You pass in the plaintext and the key and it
returns a Blowfish-encrypted string. BTW it also enhexes the string
so that you can pass the string around more easily. UserEncrypter,
BTW, is a string that getes generated elsewhere in the application
and is just used to pad out the string so that the important part of
the plaintext is divisible by 8.
==== end snippet ====
Function encipher(plaintext As String, key As String) As String
Dim bf As BlowfishCBC
dim sPlaintext As String
dim sEncrypted As String
dim sEncryptedHex As String
// initialise a new Blowfish object using the key
bf = new BlowFishCBC(key)
// Add 7 extra bytes to ensure that Blowfish will encrypt the
// entire string if its not dividable by 8
// (this is actually overkill since we determine the string length)
sPlaintext = plaintext + mid(userEncrypter,1,7)
// now encrypt the key supplied
sEncrypted = bf.Encrypt(sPlaintext) + bf.FinishEncrypt()
// and hex
sEncryptedHex = DoLocalHex(sEncrypted)
// send the encrypted and hexed string back to the calling method
return sEncryptedHex
// Reset the encryptor so if can be safely used again
bf.Reset
End Function
==== end snippet ====
I hope this helps.
Ian.

Brian,
Thanks for the reply. I've already purchased all the plugins and
am very happy with them. I was kind of hoping for a brief code
example though. I don't want to read a file and encrypt it's data,
I want to encrypt the file as a whole. One would think that you'd
just read in a BinaryStream and encrypt it, but all the Einhugur
plugins only accept strings as data, and not binary data. Needless
to say, I'm having trouble wrapping my head around how to go about
this.
Regards,
Michael

Does anyone have much experience with the e-Cryptit engine and
general
file encryption? I'm interested in encrypting/decrypting files

the file
as a whole.
I've used e-Cryptit for a couple years and have found it to be stable
and it is reasonably priced. You should not have a problem encrypting
files with it.
