PGPocx.ocx
This is an ActiveX control written in VB5 that acts as an interface
to PGP (Pretty Good Privacy) version 2.62 or later. This control
contains NO STRONG ENCRYPTION ALGORITHMS. You must have a copy of
PGP set up properly to use this control.
This control is only useful for encryption and decryption of string
data. This release does not include key management routines or other
encryption options. You are, of course, not obligated to send $$,
but if you like the control and would like to see more features, send
comments and suggestions to:
karl@cstone.net
and send the cash ($5 is fair, for my time and effort) to:
Karl Houseknecht
28 Evergreen Lane
Palmyra, VA 22963
Feel free to email me at karl@cstone.net with any questions about
the control. I will support it in a limited fashion, but I am NOT
RESPONSIBLE for anything it might do to your system.
Properties
----------
OutFile - temporary output file. Must be different than TempFile.
Pass - pass phrase for secret key
Path - path to pgp directory (e.g. c:\pgp)
TempFile - temporary input file. Must be differeny than OutFile.
UserID - user id for a public key
Text - the text to encrypt
Methods
-------
Encrypt - encrypts plaintext and outputs ciphertext in radix-64
Decrypt - decrypts ciphertext in radix-64 and outputs plaintext
Sign - Signs with private key and leaves message readable
GetUserIDs - parses pubkey.pgp and returns userid's in array.
Only works for userid's of format "user@domain".
Supports up to 100 userid's. You'll get an error
for any above this amount.
Events
------
Progress - fires every so often. No value passed to this event,
just include code to show progress (e.g. add a * to
a label.caption each time it fires)
How to Use
----------
Set these properties ALWAYS:
pgp1.OutFile = "c:\outfile.txt" 'use any filename
pgp1.TempFile = "c:\tempfile.txt" 'use any filename
pgp1.Path = "c:\pgp" 'your pgppath here
'All properties can be set at design time or run time
Public Sub EncryptThis()
pgp1.Text = Text1.Text
pgp1.UserId = "user@host"
Text1.Text = pgp1.Encrypt
End Sub
Public Sub SignThis()
PGP1.Pass = "pass phrase"
PGP1.UserId = "user@host"
PGP1.Text = Text1.Text
Text1.Text = PGP1.Sign
End sub
Public Sub DecryptThis()
PGP1.Text = Text1.Text
PGP1.Pass = "pass phrase"
Text1.Text = PGP1.Decrypt
End Sub
Public Sub ListThePubring()
users = PGP1.GetUserIDs
For i = 1 To UBound(users)
If users(i) = "" Then
Exit For
Else
lstAvailKeys.AddItem users(i)
End If
Next i
users = Empty
End Sub
