Certificate Passphrases

A certificate passphrase is a secret phrase that protects a private key associated with your certificate from being exposed.

The Bat! has an option to cache certificate passphrases.

Please do not use national characters in certificate passphrases. The Bat! uses components and functions from the Microsoft Windows API that work with the Unicode character set. If there is a configuration problem (e.g. the required input locale not being properly installed in Microsoft Windows), Unicode conversion may fail causing the certificate private keys to become inaccessible. The PFX standard is also used to export certificates with private keys, and using national characters in a passphrase may cause incompatibilities when the certificates are transferred between applications.
