Did you know that #deltachat does not need and does not use key servers? Most other messengers (wa/signal/matrix/threema/...) actually operate or incorporate a cryptographic key server, managing the cryptographic identities of all users. Delta Chat uses decentralized protocols for key management avoiding a central storage of identities. The SecureJoin protocol is the key (sic!) innovation and was independently analyzed by ETH Zürich researchers earlier this year .... https://delta.chat/en/2024-03-25-crypto-analysis-securejoin

👍 Brilliant, however (big) companies, like #apple #microsoft #google #facebook #meta , believe only in solutions they can #profit from. That's small thinking, profit oriented and definitely against a #resilence solution.

Redirection problems in lieu of localization · Issue #957 · deltachat/deltachat-pages

Reported on the fediverse It is probably related to localization and redirects, a kind of known issue that there is some mess on our nginx deployment. Should be reproducable with this link: https:/...

STOP spreading lies!

Threema does NOT have a "key-server"

Threema:

"...we don’t have the secret keys of our users (your secret key never leaves your device)"

https://threema.ch/en/faq/crypto_authorities

And btw:

#Deltachat is financed by the Open Technology Fund

https://www.opentech.fund/projects-we-support/supported-projects/delta-chat/

where to money comes from the US-Goverment

"Affiliations U.S. Government"
https://en.wikipedia.org/wiki/Open_Technology_Fund

And worst of all:

#DeltaChat betrayed metadata !

"metadata absolutely tells you everything about somebody´s life. If you have enough metadata, you donít really need content."

NSA General Counsel
Stewart Baker

In:
"We kill people based on metadata"
https://www.nybooks.com/daily/2014/05/10/we-kill-people-based-metadata/


'We Kill People Based on Metadata' | David Cole | The New York Review of Books

A bill to rein in NSA spying on Americans’ metadata has wide bipartisan support in Congress. It is an important first step, but it addresses only one part of the NSA’s vast surveillance activities.
