Two files contain IMPAX password information:
System password file
This file is encrypted with a key specific to the machine and unknown to the user, called the system key. This file is not transferable between machines and can be decrypted only on the system where it was created. It is located under the mvf directory and is named mvf.psd by default.
Note:
If the mvf.psd file already exists, do not remove it; otherwise, IMPAX services cannot start.
Portable password file
This file is encrypted with a key specified by the user, thus having a much weaker type of encryption. It is created upon user request, and should be deleted when no longer required. This key can be used to transfer passwords between systems during the installation of IMPAX.
