pgg-encrypt and confirming passphrase

[Peter Rayner]

I recently managed to mistype my passphrase for pgg-encrypt and hence
seem to have locked away some data.  I would like to avoid this in
future by demanding a confirmation of a passphrase in the style of the
unix passwd command.  This doesn't seem to be an option.  Before I go
ahead and advise the function to provide this, I would like to confirm
that I'm not reinventing the wheel.  So is this already possible?
Please contact me off list since I don't always keep up 
regards
Peter
