• In MS Outlook/Outlook Express, how to encrypt e-mails?

  Encrypted e-mail adds another security featurEncrypted e-mail adds another security feature because it prevents a third party entity to see the actual content of the e-mail, and it also protects sending of e-mail message thru an unsecure medium (e.g. a compromised wireless network). Take note that you can't just encrypt any e-mail that you want to send. You also have to make sure that your recipients can decrypt the encrypted email you have just sent. That means that Encrypting an e-mail message with your own Digital Certificates and sending it out to your intended recipients will be useless, since you are the only one that can decrypt the e-mail that you have just sent. Your recipients cannot decrypt your email and thus would not be able to read it. This also means that people who wants to send This also means that people who wants to send you an encrypted email should have a copy of your public key. The public key is the one needed to encrypt emails that people want to send to you. If you want to send your recipients a copy of your certificate then all you have to do is send a signed email. On the other hand if you have received a signed On the other hand if you received a signed email, you can also reply to that email and have it encrypted.

• In Thunderbird, how to set up digital certificate?

  Before Signing/Encrypting an E-Mail, Thunderbird should know which Digital Certificate(s) to use for each operation. Make sure that you already had requested a Digital Certificate from a Certificate Authority before doing the steps below. To set-up the digital certificate to be used for signing/encrypting e-mails in Thunderbird: First, make sure that you have requested a certificate in a Certificate Authority and that you have Installed the ACS' PKCS#11 Module in Thunderbird. The e-mail address that you registered when requesting a certificate SHOULD be the same e-mail account that you are using in Thunderbird. After successfully requesting a digital certificate. Launch Thunderbird. Navigate to "Tools" -> "Account Settings". The "Account Settings" window will be displayed. Select the "Security" section on the tree-view on the left side (Figure 1). Figure 1: Security Account Settings in Thunderbird. Notice that there are 2 Panels, each for "Digital Signing" and "Encryption". Click the "Select" button. A password dialog box may appear, enter your PIN here (Figure 2). Figure 2: When asked for a Master Password, enter your card/token PIN. After successfully entering your card/token PIN, you should now see a "Select Certificate" dialog. Select the certificate that you want to use for signing/encryption. You will also see where the certificate(s) are stored. The "Stored in" property of the certificate will tell you in which card/token the selected certificate is stored. The value "Stored in" property should be the same Token Name of your card/token (Figure 3). Figure 3: Select Certificate dialog in Thunderbird. Select the appropriate signing/encrypting certificate and then select "OK". Your Security Panel should now look like the one below (Figure 4).

• How to sign PDF documents?

  Using the Adobe Professional Suite and ACS' CSP Middleware, users can sign and encrypt PDF documents using certificates that are stored on the ACOS5 Card/CryptoMate devices. Before signing PDFs, user must ensure that he/she had requested a digital certificate from a trusted CA. As an example, we will use Adobe Professional Suite 8 for the steps discussed below.   Signing your PDF documents ensures that your document had not been tampered since the signature has been applied. This security feature is particularly important when sending your document through e-mails. To put your digital signature on a newly created PDF document: Make sure that your ACOS5 card is inserted in the reader. If you are using a CryptoMate Device, make sure that it is inserted in a USB slot. Start the Adobe Professional Suite.If you have properly installed the Adobe Pro Suite, you should see a welcome screen similar to the one below (Figure 1). Figure 1: Creating a PDF using Adobe Pro Suite 8. Select "CREATE PDF". You can easily create a PDF document that comes from a *.doc, a .txt file or even from multiple files. Select the proper source file for your PDF documents (Figure 2). Figure 2: Select the appropriate source file in creating your PDF document. Once you have selected the proper source file for your PDF document, you can now start signing your documents. Note that you have to save the newly generated pdf file before you can put a digital signature in it. In the main panel of the Adobe Pro Suite, Click the "Sign" Drop Down button (Figure 3). Figure 3: Signing your document with a digital certificate. You can see from the drop down menu that you can choose how you will place your digital signature in a pdf document. For the purpose of this example we will choose "Certify with Visible Signature". Once you have chosen how to put your digital signature in the document, you will be prompted as to where to place the digital signature in the document. After this, you will also be prompted to choose which specific Digital Certificate to use for document signing Choose what particular Digital Certificate you want to use to sign your PDF document (Figure 4). If you can't see your digital certificate, try to re-insert the ACOS5 card or CryptoMate token and repeat Steps 5 to 7. If re-inserting your card/token does not solve the issue, restart the Adobe Suite or try the steps discussed here. Figure 4: Select which digital certificate to use for digital signing. Once you have selected which digital certificate to use for document signing, you will be prompted to enter your ACOS5 PIN. In this step you will also see how your Digital Signature is placed in the PDF document. Figure 5: Enter your Card/Token PIN. Upon entering the correct card/token PIN, your document will have a permanent watermark. This watermark indicates who signed the document. Upon giving your document to someone else, they will see the document having this watermark (Figure 6). Figure 6: The newly created PDF document as viewed in an Acrobat Reader 7. The user who is viewing this document can verify if the document has been modified since it was signed. By Double Clicking the watermark, the "Signature Properties" dialog box will show up. This shows information regarding the document modifications and the digital signature itself (Figure 7). Figure 7: Signature Properties of the Digital Signature embedded in a PDF document.
