I want to convert UTF-8 encoded strings into some sort of irreversible hash *and* maintain correct sort order (or the ability to lexically compare strings).
If I say "Order-Preserving Hashing with Prefix-Free Encoding", what do you say? 🤔
The problem I foresee (with great wisdom 👀) is dictionary attacks, thus not being actually "irreversible".
Merkle-tree: Как проверить целостность данных без полного доступа?
Хэширование — простой и надёжный способ проверить целостность данных. Но как быть, если нужно удостовериться, что часть данных принадлежит определённому набору ? Например, проверить отдельную транзакцию в блоке Bitcoin или чанк файла в BitTorrent? Для этого используется уникальная структура данных — Merkle-tree . В этой статье вы узнаете, как с её помощью решать задачи проверки данных без доступа к их полному объёму.

For medical records you can imagine we want to know, and show, that the record we see is the record that was made, all of it, and only it.
This may be accomplished by passing the (element of the) record through a #trapdoor #function, or #hashing #algorithm such as SHA1 (secure hash algorithm 1) and sending the hash somewhere else.
The hash is small, compared with the medical note, and tiny compared to a photograph.

Saying that blockchains are inherently bad is like saying that knifes are inherently bad.
Yes, they can be used for bad things. But also good things: Just consider Torvald's Git software version control implementation.
@liw Have a look at the "RustCrypto: #Password Hashes" project:
https://github.com/RustCrypto/password-hashes
They provide all kinds of password-hashing algorithms, like:
- Argon2
- PBKDF2
and many more
Just started work on the planned "single instance mode" for #Xmoji.
The first commit is done, adding a class implementing the core functionality using a local #Unix #socket. Part of the job is deriving a unique name for that socket, where #hashing comes natural.
I had a similar class in #qXmoji (based on #Qt), and there you have #sha256 at your fingertips with
Without all these helpers from Qt, first thing I did now was searching the web for a "good" hash function, but there's certainly no need for a cryptographic one. I found #FNV1a. It's super easy to implement in #C. And for the base64 part, well, doing it myself, I can directly use a modified set of digits, without the
Now, here's the whole thing:
https://github.com/Zirias/xmoji/commit/db764e3184537d42b528e718bd4886495eb45544
I'd say that's a nice example how not having lots of "powerful" library functions readily available can lead to a much better (smaller, more efficient) solution. 😏

QCryptographicHash, so I just used that. You need a string from that, and sure thing, there's a .toBase64() method.

So ... due to an early obsession with historical BSD hashes ... I have significantly more bcrypt hashrate-per-watt cracking capacity than most solo shops. For bcrypt cost 12, it's about 34Kh/s straight wordlist -- the equivalent of about 17 4090s -- at only 1100W (these old Bitcoin FPGAs are very efficient for bcrypt specifically). And this capacity is intermittently idle, which is kinda a shame.
I haven't really put it out there as something I can help with if needed (outside of the Hashcat team). So ... feel free to ping me if you need bcrypts cracked/audited!
(Reasonable rates, but note that I do have a pretty firmly high bar for provenance / proof of authorization)
(Rat's nest of USB has been cleaned up a bit 😅)
Can somebody help me with this? 😂
While trying to do memory-hard hashing in #Bash without using external tools aside from #OpenSSL I came up with this thing: https://pastebin.com/D3vqgW7N
It seems to hash the password, but when using a fixed salt, the hash does not change, even with a different password.
Thus, I am not sure if this is trustworthy.
I'd be very glad if somebody could help me here 🙂
