Chapter 16 Certificates • Binary PKCS#12: This is a format for transferring public key and private key certificates.The private key in a PKCS #12 file is within a password-encrypted envelope. The file's password is not connected to your certificate's public or private passwords. Exporting a PKCS #12 file creates this and you must provide it to decrypt the contents when you import the file into the Zyxel Device. Note: Be careful not to convert a binary file to text during the transfer process. It is easy for this to occur since many programs use text files by default. 16.1.3 Verifying a Certificate Before you import a trusted certificate into the Zyxel Device, you should verify that you have the correct certificate. You can do this using the certificate's fingerprint. A certificate's fingerprint is a message digest calculated using the MD5 or SHA1 algorithm. The following procedure describes how to check a certificate's fingerprint to verify that you have the actual certificate. 1 Browse to where you have the certificate saved on your computer. 2 Make sure that the certificate has a ".cer" or ".crt" file name extension. 3 Double-click the certificate's icon to open the Certificate window. Click the Details tab and scroll down to the Thumbprint Algorithm and Thumbprint fields. 4 Use a secure method to verify that the certificate owner has the same information in the Thumbprint Algorithm and Thumbprint fields. The secure method may vary based on your situation. Possible examples would be over the telephone or through an HTTPS connection. NWA/WAC/WAX Series User's Guide 156
