Select older algorithms (as AES-128 or RC4) only, if you need backward compatibility. Also, choose a strong password to ensure strong encryption.&lt;/p&gt;&lt;p&gt;Public key security using certificate is also supported. In that case, you must select a certificate with private key, and this certificate is then used to encrypt data. User, which wants to open document encrypted with certificate, must have a private key to the certificae.&lt;/p&gt;&lt;/body&gt;&lt;/html&gt;</string>
