     Why should I trust PGP-ICQ?
    PGP-ICQ is an open source software, so anyone can examine its source code and see for yourself that it does not contain security leaks or compromise your privacy.

    But remember that anyone can modify the program code and redistribute it. We DO NOT GUARANTEE that a copy of PGP-ICQ downloaded from a website other than www.samopal.com does not contain viruses (including trojans) and security backdoors.


     What are current versions of Windows and ICQ supported by PGP-ICQ?
    The latest version of PGP-ICQ (release 0.9) works on Windows 95/85, Windows NT 4.0 and Windows 2000.
    ICQ versions that are supported by PGP-ICQ are 99a, 99b and 2000a. It has not been tested with ICQ98 and ICQ2000b.


     Why does PGP-ICQ ask me for a passphrase?
    The passphrase is needed to make sure that only you can access your private PGP key for decrypting messages. You choose a passphrase when generating a new key pair with PGP. PGP-ICQ asks for the passphrase only once per session and does not store it on the hard drive or in the system registry.


     Can the incoming messages be auto-decrypted?
    Yes. It's kind of annoying to click the Decrypt command every time you receive an encrypted message. In PGP-ICQ options window you can turn auto-decryption on and off (it's off by default).


     Can the outgoing messages be auto-encrypted?
    This will be implemented in the future versions of PGP-ICQ.


     Is it possible to sign messages and verify signatures?
    This will be implemented in the future as well.


     Does PGP-ICQ encrypt the message archive?
    Yes. All the messages you send or receive encrypted are stored in the message archive also encrypted. PGP-ICQ can decrypt encrypted messages for you when you browse the message history.


     I don't see the promised PGP button in my ICQ windows!
    You're most likely using ICQ 2000 in the split message mode. PGP-ICQ will not work in that mode, and you need to switch to the single message mode.

    In the split message mode ICQ combines all the messages in one piece of text, so there is no way to distinguish incoming messages from outgoing ones, and therefore there's no way to find out which PGP key should be used to encrypt and decrypt them. That's the reason why the PGP button is disabled in this mode.

    The split message mode WILL be supported in the next version (that would be 1.0).


     I receive the "Message cannot be decrypted" error.
    Start the pgpKeys program (the one that comes with PGP-ICQ) and see if there's a default key (if you only see "Public keys" and "Key pairs", you need to make one of "Key pairs" default (right-click and "Set as default"). PGP-ICQ decrypts messages using your default private key from the "Default key pair". When there's no default key, PGP-ICQ fails to encrypt.

    Another possible reason for that error is that the sender used someone else's (not yours) public key to encrypt the message.


     I receive the "Message cannot be encrypted" error.
    Start the pgpKeys program (the one that comes with PGP-ICQ) and see if there's a default key (if you only see "Public keys" and "Key pairs", you need to make one of "Key pairs" default (right-click and "Set as default"). PGP-ICQ encrypts messages to two public keys: the recipient's public key (so the recipient can decrypt your message) and your public key from the "Default key pair" (so you can decrypt your message archive). When there's no default key, PGP-ICQ fails to encrypt.


     How do I send my public key(s) to other people?
    The latest version of PGP-ICQ allows users to exchange public keys via ICQ.

    Or you can upload your key to the key server (using the "Send to Server" command of the pgpKeys program), so other people can search for your key and download it to their key sets.

    You can also save any public key(s) from your key set to a file (using the "Export to File" command of the pgpKeys program), and send this file via email to anyone.


     I examined the source code and found a terrible bug!
    Wow! Please let us know! We greatly appreciate this kind of help.


     You guys are so cool. How can I support you?
    We do not charge money for PGP-ICQ and its source code. It's absolutely free. But you can support us by clicking our sponsor's banners on this website.

    If you'd like to support us in any other way so we can continue developing PGP-ICQ, please contact us.

     What in the world took you so long to release a new version?
    Eh... we've been sort of busy.
