When you run the pgpwde --add-user or pgpwde --secure command at a Microsoft Windows command prompt, the passphrase is accepted when entered as input on the Command Line, but the passphrase fails to authenticate successfully at the pre-boot authentication (BootGuard) prompt. The same complex passphrase may work correctly on the Symantec Encryption Desktop (previously PGP Desktop) graphical user interface.
Note: The PGP product line has been renamed. For a detailed map of old product names to new ones, refer to the Symantec Knowledgebase article TECH197084.
The passphrase authentication fails when you enter certain special characters using Command Line, without the escape character. These special characters are not saved properly on the hard disk used for Drive Encryption. This causes the user authentication failure even when the correct passphrase is entered at the pre-boot authentication prompt.
A few special characters are interpreted differently when used in the Windows command prompt. Hence, you should precede the caret (^) escape character with the '&' and '>' characters at the Windows command prompt. However, using the Caret character does not solve the issue if a passphrase has double quotes in it.
Note: The same complex passphrase may work correctly without the use of the Caret character on the Symantec Encryption Desktop graphical user interface.
