OpenPGP mit XMPP - Wie funktioniert dies eigentlich?
DebXWoody · Sunday, 2 August - 08:42 · 1 minute
Um Nachrichten zu signierten und / oder zu verschlüssel kann bei XMPP OpenPGP verwendet werden. Die Erweiterung wird in XEP-0373: OpenPGP for XMPP (OX) beschrieben.
Wie funktioniert dies?
Alle Teilnehmer besitzt je ein Schlüsselpaar. Also einen private und einen öffentlich Schlüssel. Wem dies noch nicht bekannt ist, es gib ein sehr gut gemachtes Video. XEP-0373 beschreibt wie ein XMPP Client einen öffentlichen Schlüssel im "Personal Eventing Protocol" (PEP) abspeichern kann. XMPP Nutzer können so auf das PEP des Kommunikationspartner zugreifen und dessen öffentlichen Schlüssel beziehen.
Im ersten Schritt werden die im PEP gespeicherten öffentlichen Schlüsse abgefragt. Die Rückgabe ist eine Liste der Fingerprints. Danach kann der Client die öffentlichen Schlüssel pro Fingerprint abfragen und importieren.
Wenn der öffentliche Schlüssel des Kommunikationspartner bekannt ist, kann die Kommunikation via OpenPGP erfolgen. I.d.R. sollte man drauf achten, dass man den öffentlichen Schlüssel des Kommunikationspartner signiert hat. Denn nur durch den Abgleich des Fingerprints und des unterschreiben des öffentlichen Schlüssel, kann sichergestellt werden, dass der Schlüssel wirklich der richtige ist.
Ich habe angefangen OX in profanty zu implementieren. Hierzu werden ich demnächst ein kleinen Eintrag im Blog von profanity vornehmen.

The F-word’s hidden superpower: repeating it can increase your pain threshold

There have been a surprising number of studies in recent years examining the effects of swearing , specifically whether it can help relieve pain—either physical or psychological (as in the case of traumatic memories or events). According to the latest such study, published in the journal Frontiers in Psychology, constantly repeating the F-word—as one might do if one hit one's thumb with a hammer—can increase one's pain threshold.
The technical term is the " hypoalgesic effect of swearing ," best illustrated by a 2009 study in NeuroReport by researchers at Keele University in the UK. The work was awarded the 2010 Ig Nobel Peace Prize, "for confirming the widely held belief that swearing relieves pain." Co-author Richard Stephens, a psychologist at Keele, became interested in studying the topic after noting his wife's "unsavory language" while giving birth, and wondered if profanity really could help alleviate pain. "Swearing is such a common response to pain. There has to be an underlying reason why we do it," Stephens told Scientific American at the time.
For that 2009 study, Stephens and his colleagues asked 67 study participants (college students) to immerse their hands in a bucket of ice water. They were then instructed to either swear repeatedly using the profanity of their choice, or chant a neutral word. Lo and behold, the participants said they experienced less pain when they swore, and were also able to leave their hands in the bucket about 40 seconds longer than when they weren't swearing. It's been suggested (by Harvard psychologist Steven Pinker, among others) that it is a primitive reflex that serves as a form of catharsis.
500-year-old manuscript contains earliest known use of the “F-word”

Scotland has much to recommend it: impressive architecture, gorgeous Highlands, and a long, distinguished intellectual tradition that has spawned some of the Western world's greatest thinkers over several centuries. It's also, apparently, home to a medieval manuscript that contains the earliest known usage of the swear word "F#$%."
The profanity appears in a poem recorded by a bored student in Edinburgh while under lockdown as the plague ravaged Europe—something we can all relate to these days. The poem is getting renewed attention thanks to its inclusion in a forthcoming BBC Scotland documentary exploring the country's long, proud tradition of swearing, Scotland—Contains Strong Language .
The Bannatyne Manuscript gets its name from a young 16th-century Edinburgh merchant named George Bannatyne , who compiled the roughly 400 poems while stuck at home in late 1568, as the plague ravaged his city. It's an anthology of Scottish literature, particularly the texts of poems by some of the country's greatest bards (known as makars ) in the 15th and 16th centuries. According to a spokeswoman for the National Library of Scotland (where the manuscript is housed), "It has long been known that the manuscript contains some strong swearwords that are now common in everyday language, although at the time, they were very much used in good-natured jest."
