his public key is 5 monitors high, and her same key is 1 ?

[shmick at riseup.net]

what are the factors involved in creating such discrepancies with folks'
public key lengths ?

i mean, some people's are 5 monitors high where as the other joe has
seemingly created a similar key and that key is one half a monitor in
'monitor' height

what does all this mean ?
how have people such varying public key 'sizes' ?
and how is this achieved ?

are public, private, and key pairs in general stronger/safer (what ever
that may mean) if observing their public keys are many monitors high or
have they gone to extreme measures in something in particular ?
