An SSH key's randimart image, but instead of many random graphics chars, just a single "4" in the middle of a large, empty space.

For those bitten by #eMudhra, as well, here is a collection of some memes which were shared with me on the occasion.

I hope you enjoy them. You know of more? Share them, please! (#PHP2shell #PHPocalypse is acceptable, too.)

Don't forget to `s/RSA/ECDSA/` in the first two.

Heatmap used for visualizing password strength. However, not all of the low entropy choices are given as "immediate"; 1-, 2- and 3-character digit-sequences are listed as "18 months"

However, I *do* know the source of this one. But why did it not cross *my* mind and a friend had to send it to me?

@marcel Don't forget about the number "half six", between 2 and 4. Seems it's broken, and I didn't see a fix out yet, so be careful!

Die Originaltabelle schon. Aber jemand hat die, äh, leicht "verbessert". Und da weiss ich nicht, wer das gemacht hat.

Hint: Drei Felder sind anders.

@marcel Und trotzdem sollen ja die modernen Passphrasen so viel sicherer sein?
„Meine-Grossmutter-wird-nächstes-Jahr-87-Jahre-alt!“ - na klar, schön für die Grossmutter und dass du ihren Geburtstag nicht vergessen wirst… aber ich selber halte es ganz klar nach wie vor mit der Tabelle oben (16+ mit allem). 🤷‍♀️

Es geht hier um die drei roten Felder links oben.

Und ja, mit einer zufälligen Passphrase (nicht einem Zitat aus einem Buch oder Film!) kabnst du recht viele Bits an Entropie memorieren.

(Muss meinen Passphrase-Generator mal einen Schritt weiterbewegen…)
