The only choice if you need security is random_device.

(In [62629]) Add an example of generating a random password. Fixes #4183

To whom it may concern:

I believe there is a typographical error within your recommended code password.cpp. Specifically, the last line defining the character string contains two open curly braces { and no close curly brace }. (http://www.boost.org/doc/libs/1_50_0/libs/random/example/password.cpp):

"`~-_=+[{]{\\|;:'\",<.>/? ");

I believe the correct entry should be:

"`~-_=+[{]}\\|;:'\",<.>/? ");

However, the impact of this on random password generation is minimal.

Respectfully,

JRSmith

It's really better to file a new ticket instead of tacking this onto an existing (closed) ticket. I almost missed this.
