It remains a difficult phenomenon to truly understand: #opensource or #digitalcommons are often kept out with great conviction, justified by claims of immature #security and unacceptable risk.

Yet that same conviction is rarely seen when consensus relies on decades-old security components that have caused harm for over 30 years.

Security, then, seems less a principle than a convenient argument used when it suits other interests.

supported by default for 26 years following more than a decade of devastating #hacks that exploited it & recently faced blistering criticism from a prominent senator. When the software maker rolled out #ActiveDirectory in 2000, it made #RC4 a sole means of securing the #Windows component, which admins use to configure & provision fellow admin & user accts inside large orgs

An #SJ #Rc4 electric is hauling the consist on this photo taken in August 1985. With an #Interrail ticket in my pocket, I travelled by train from #Stockholm 🇸🇪 to #Narvik 🇳🇴, a ride of over 1,500 kilometres.
One can still do this today: the voyage currently lasts about 19 hours.

Cryptohack. Решение Oh SNAP. Атака Флюрера-Мантина-Шамира (Fluhrer, Mantin, Shamir)

Приветствую, Хабр! В нескольких предыдущих статьях я рассматривал различные режимы шифрования для блочных шифров, постепенно сдвигаясь в сторону режимов, превращающих блочные шифры в потоковые. В новой статье в фокусе будет чисто потоковый шифр - RC4. Я расскажу о самом шифре, а также об атаке FMS и применении её для решения задачи Oh, SNAP с платформы Cryptohack.

Anyways, I guess we should all use export-grade #cryptography since I can call all those named into existence in about 45 minutes, and anyway there are still several a trillion keys in 40 bit space, that's still like 100 keys per person.

Ich bin dafür, dass diese Leute ihre Kommunikation mit ihrer Bank per #Clipperchip oder #RC4 „schützen“. #CryptoWarsPartN

Ansonsten #Buchtipp, der alte Klassiker:

The #LastPass password generator uses a userspace #RC4 generator.

Here's their #JavaScript:

dogenerate() -> lpCreatePass() -> get_random() -> rng_get_bytes() -> rng_get_byte() -> prng_newstate() -> ARC4init(); ARC4next()

As RC4 is insecure, you would be wise not to use their web-based password generator.

Further, it seems likely they're using the same code in their password manager. You would be wise not to use it there also.
