Decrypting emails and files

When someone sends you encrypted data, you can unscramble the contents
and verify any appended signature to make sure that the data originated with
the alleged sender and that it has not been altered.
You can decrypt files using PGPtools:
1. In the Windows Explorer, select the file or files that you want to decrypt.
2. Drag the file onto the Decrypt/Verify button in the PGPtools window. The
PGP Enter Passphrase dialog box appears, asking you to enter your
passphrase.
3. Enter your passphrase and then click OK. If the file has been signed, a
message appears indicating whether the signature is valid.
4. Click OK.
The decrypted file is saved in the same location as the original file.

PGPdisk

PGPdisk is an easy-to-use encryption application that enables you to set aside
an area of disk space for storing your sensitive data. This reserved space is
used to create a file called a PGPdisk volume.
Although it is a single file, a PGPdisk volume serves very much like a hard
disk in that it provides storage space for your files and applications. You can
consider it as a floppy disk or an external hard disk. To use the applications or
open the files stored in the volume, you need to mount it to make it accessible.

• If you are using an email application that is supported by the
plug-ins, you can decrypt and verify your messages by selecting the
appropriate options from your application's tool bar.
• If your email application is not supported by the plug-ins, you can
copy the message to the clipboard and perform the appropriate
functions from there. If you want to decrypt and verify file
attachments, you can do so from the Windows clipboard. You can
also decrypt encrypted files stored on your computer, and verify
signed files to ensure that they have not been tampered with.
