Greg based on your analysis I have closed this issue.  Clearly it wasn’t going 
to make it into 16.40 given that features are done at this point.

Re: Private key protection support for using passphrase not applicable for

After discussing with Kevin 
Kane<https://jira.allseenalliance.org/secure/ViewProfile.jspa?name=kkane> we 
decided this feature is not worth adding.

In Security 2.0 world everything is kept in the keystore, so there’s not as 
much of an issue. The only real use case for the app to supply credentials are 
Security 1.0 interactions using ECDSA. Also, this mechanism is difficult to use 
in a way that provides strong security, since the passphrase must have high 
entropy, there is little security when the typical user-chose passphrase is 
used. If you don't use a user-chosen secret, you have two private key 
protection problems.

A workaround for apps that need additional protections is to implement them in 
the app.

Private key protection support for using passphrase not applicable for 
ECDHE_ECDSA mechanism.<https://jira.allseenalliance.org/browse/ASACORE-1715>


Typically, private keys are protected by passphrase. In AllJoyn for RSA 
mechanism, the library would take the password protected key and the password 
and would decrypt the private key. The mechanism was supported because AllJoyn 
used OpenSSL to do so.

This mechanism is no longer supported by the library for ECDHE_ECDSA. This 
means that the user will h...
