Here’s a fun and accessible framing of the history of why you can buy things and chat securely on the internet. It continues to be a question of whether it is a right or privilege. That conversation is not over. This is a good place to join it:

Generate Random Data From Sound Card

- a neat hack for the properly paranoid -

Your computer is likely generating random noise on your sound card. On some systems you can harvest this noise as true random entropy. This entropy can be diffused and whitened for use in cryptography.

About 18 years ago, I wrote an implementation of the VIC cipher for Flash. Someone emailed me out of the blue yesterday asking if I'd ported it to #JavaScript. Well, here it is. I published it on the #npm registry. It should work with #deno as well, if you prefer that.

Al Gore Invented the Internet.
Joe Biden invented PGP encryption.
Cypherpunks write code.

Joe Biden gifted humanity with PGP encryption (in a roundabout way). Phil Zimmermann created PGP in response to a anti-privacy bill clause proposed by Senator Joe Biden.

https://www.americanscientist.org/article/cypherpunks-write-code

"In 1990, the FBI launched an over-the-top crackdown on computer hackers, known as Operation Sundevil. This was swiftly followed, in early 1991, by a proposed piece of U.S. Senate legislation that would force electronic communications service providers to hand over people’s personal data. (The key clause, S.266, was pushed by the then chairman of the U.S. Senate Judiciary Committee, Senator Joe Biden.)"

"On learning of Biden’s S.266 clause, Zimmermann feverishly set out to complete the project, almost losing his house in the process. When he finished his software in 1991, he published it all online, free for anyone who wanted to use it. He called it “Pretty Good Privacy,” or PGP for short, and within weeks it had been downloaded and shared by thousands of people around the world. “Before PGP, there was no way for two ordinary people to communicate over long distances without the risk of interception,” said Zimmermann in a later interview. “Not by phone, not by FedEx, not by fax.” It remains the most widely used form of email encryption to this day."

Joe Biden's first panopticon bill:

https://www.congress.gov/bill/102nd-congress/senate-bill/266

"SEC. 2201. COOPERATION OF TELECOMMUNICATIONS PROVIDERS WITH LAW ENFORCEMENT. It is the sense of Congress that providers of electronic communications services and manufacturers of electronic communications service equipment shall ensure that communications systems permit the government to obtain the plain text contents of voice, data, and other communications when appropriately authorized by law."

As they say in Texas: That dinosaur don't hunt.

#CRYPTOGRAPHY DOES NOT EXIST IN A VACUUM.

#introduction
Never got around to doing the Twitter thing, but figured I’d give Mastodon a whirl. So, hey.

I’ve been in #InfoSec for a good while now, from handling all manner of different things to varying degrees at a smaller company launching a dedicated security department, to focusing on #AppSec and #ProductSecurity at larger entities more recently. Dealt with #PaymentsCompliance A Lot over the years, including the #cryptography related standards.

RE: https://mastodon.social/@reiver/115945290105913697

Right now, Fediverse IDs resolve to HTTPS URLs.
For example, the Fediverse ID:

＠reiver＠mastodon.social

Resolves to HTTPS URL:

https;//mastodon·social/users/reiver

...

If we wanted cryptographic public-keys to serve as a basis of Identity on the Fediverse, then —

We would (similarly) also need a Fediverse ID to resolve to one or more cryptographic public-keys

PERFECT PANGRAM HASH : Anagram Hash Function

#DOI https://doi.org/10.5281/zenodo.18448042

A pangram is a sentence or phrase that contains each letter of an alphabet or character set at least once. A perfect pangram is an anagram of the alphabet which contains each letter exactly once.

Pangram hash generates a perfect pangram hash digest consisting of a anagram permutation of a character set. Each character in the output is unique and non-repeating.

Cryptographic public-keys are one way that one can have an identity (on the Fediverse, and elsewhere) while also having privacy — through a pseudonymous identity.

Yes, we have Fediverse IDs such as:

＠joeblow＠example.com

But a (non-delegated) public-key can function as a PORTABLE form of identity on the Fediverse.

#ActivityPub #Cryptography #Fedidev #Fedidevs #Fediverse #JSONLD

One way ActivityPub can be extended is — through JSON-LD namespaces.

For example, many Fediverse servers use the following JSON-LD namespace to specify cryptographic public-key(s) for the user.

https://w3id.org/security/v1

(This particular namespace is an HTTPS URL.)

...

But, does extant Fediverse software support cryptographic public-key(s) well?

How to Upgrade GnuPG to Generate Kyber and Goldilocks Keys

I see some people still using ancient PGP keys. GnuPG offers Linux repositories for updating to the latest versions of GnuPG with new expert features for key generation. Recent versions support both Kyber1024 and Goldilocks448 keys (and more).

Once installed run: :~$ gpg --full-generate-key --expert

Happy 2026 from OffSeq 🥂
Wishing everyone a strong, successful & secure year.

📡 Threat Radar (radar.offseq.com) has moved to a larger server after significant growth — 100k users and ~500k events last month. Timeline updates will resume shortly.

🔐 In the meantime, meet Veil — a local-only steganography studio.

Veil encrypts text or files in your browser and embeds them into PNG images using LSB techniques.
No servers. No uploads. No tracking.
The image looks normal — the contents stay encrypted unless the password is correct.
