I completely forgot that I had posted this question here... following is how I resolved this issue:
Microsoft Healthvault setup in PHP
Files needed:
app.pem
RSA private key
app.cer
Certificate file
app.id
Application ID
app.fp
Application thumbprint
Generating PEM and CER files
Download and install Microsoft Healthvault SDK
http://msdn.microsoft.com/en-us/healthvault/bb688183
Install as an administrator
Once installed create new application
Click ‘Create New Application’ button
Uncheck ‘Automatially…website…application’ box
Click ‘Create and Register application’ button
It will create a certificate name ‘WildcatApp-<appid>’
app.id will contain <appid>
At this point you can click on the ‘HealthVault Application Configuration Center’ link and setup your HealthVault application.
Generate the PFX file
Right-click on your ‘Certificate Name’
Click ‘Export public and private keys (.pfx)’ menu item
Select the desired location for the .pfx file, preferably in third_party/microsoftHealthVault/authentication
Converting PFX file to certificate and private key files
Do this in your linux vm, you should at this point have access to .pfx file because you put in location mentioned on 3.c
You will need to use ‘openssl’ to do the next steps
Generate app.cer
openssl pkcs12 -in <filename>.pfx -clcerts -nokeys -out app.cer
press ‘enter’ when asked for ‘import password’
This file should only contain text starting at ---BEGIN CERTIFICATE--- to ----END CERTIFICATE---- everything before and after should be deleted
Now you have app.cer file
Generate app.pem
openssl pkcs12 -in <filename>.pfx -out app_enc.pem –nocerts
press ‘enter’ when asked for ‘import password’
type in your host windows login password for ‘PEM pass phrase’
This will generate an encrypted private key file
The encrypted private key file needs to be unencrypted to be able to use in the application
openssl rsa -in app_enc.pem -out app.pem
Now you have the app.pem file
Log in to your healthvault configuration screen to get the app id and thumbprint
https://config.healthvault-ppe.com/default.aspx
Copy the ‘Application Id’ and insert it in the app.id file
Click on the ‘Application Id’
Click on the ‘Public certs’ tab
Copy the ‘Thumbprint’ and insert it in the app.fp file
At this point your app.cer, app.pem, app.id, and app.fp files are ready to be used.
