APPENDIX 1 – AMPLIVOX ‘ENCRYPTION’ FOR ENCRYPTION
& DECRYPTION
A1.1
Introduction
A number of software applications are readily available for the encryption and decryption of .cry files. A web
search should provide suitable options.
As an alternative, ‘encryption’ is freeware software available from Amplivox which can be used to encrypt and
decrypt .cry files for use with the CA850 audiometer and Audibase.
The freeware is supplied as a file named
‘Amplivox encryption.exe’ and may be obtained directly from
Amplivox by emailing
with a request for the ‘encryption’ freeware. To bypass firewalls
it may be necessary for the file extension to be renamed prior to emailing. After saving the attachment, rename
the file extension back to ‘exe’.
As freeware, Amplivox provides no warranty (implied or otherwise) regarding this software and will
not be liable for any aspect or consequences of its copying or use on a 3
rd
-party computer. By
downloading and/or running the application the user accepts these conditions.
No installation is necessary. Simply copy the Amplivox encryption.exe file to a suitable location and run it in
the usual way (e.g. by double-clicking on the filename). The file may be renamed if required.
The following sections describe the operation of encryption.
A1.2
Encryption (prior to importing data into the CA850)
Run
‘Amplivox encryption.exe’ and the following window will open.
To locate a file to encrypt, click the
button next to the ‘unencrypted file’ field and browse to find the required
file in the usual way. Select the file to encrypt
and click on the ‘Open’ button. Note that ‘exportdata.csv’ is the
default CA850 audiometer filename for importing and exporting data without encryption). This is illustrated in
the window below.
