KeePass or any other password wallet to store and transport keys

[John]

Hello.  I use both too, but I do so mainly due to the convenience it 
provides without apparently introducing additional weakness to my system. I 
put the key names, not the actual code with the keys themselves, into the 
Keepass database so that I can have handy access to the passwords for them. 
All of these entries are protected by a master password, no less so than as 
they were when stored in a file, but much more accessible.
