How to generate a self signed certificate for backup encryption with ZWC

This article is for Amanda Enterprise (AE)

Info Description

PFX (Personal Information Exchange) certificates are used for encrypting ZWC backup archives.

There are two kinds of PFX certificates – signed certificates and self-signed ones.

Signed certificates are issued by a recognized/trusted certificate authority (CA) such as Verisign, Comodo. The list of Certificate Authorities approved by Microsoft is here. You can find an explanation of the differences between signed and self-signed certificates here.

Unless your backup data is to be sent to some external party (which may want to verify the authenticity of data), self-signed certificates can be safely used for encryption with ZWC. You can generate your own self-signed certificate for free using OpenSSL or Abylon SELFcert tool.
