#git practically advocates abbreviating SHA-1 !crypto hashes to 7 hexits; #redmine habitually abbreviates them to 8; somehow this never collides with the notion that "the unlikelihood of hash-collisions is astronomical because it's SHA-1". -

For every person who understands all of the implications of abbreviating a !crypto #hash, I wouldn't be surprised if there are a million who can't imagine there's any problem. -

if you truncate the checksum collisions will happen sooner. -

@lnxw48 @bobjonkman There is a new #KeepassX version in works (alpha currently) that is compatible with #Keepass v 2, and it's stable enough. -

@bobjonkman ... It has been some time since I’ve used or even seen #Lastpass, so I can’t offer any insight.

@bobjonkman #Keepass v.1.x does not need Mono, and it is the version that #KeepassX, #KeepassDroid, etc are compatible with.

The only time self-signed certificates are insecure is if you don't verify the certificate signature. It is always necessary to verify a certificate's signature out-of-band. Usually that's done by a Certificate Authority (with pre-defined CA certs bundled with the browser), but certificate signatures can also be verified through other secure channels, eg. In-person, GnuPG message, … -
