@cassiopeia the curve OID

@q you need to zero-pad if you have leading zeros. Otherwise, you have a timing vulnerability.

@cassiopeia

echo '-----BEGIN EC PRIVATE KEY-----
MA8CAQEEAQSgBwYFK4EEACI=
-----END EC PRIVATE KEY-----' | openssl ec -text

[dequbed@mastodon.chaosfield.at]

@hanno @q Oh no! Once again honest cryptography is foiled by evil compression!

[q@glauca.space]

@cassiopeia here's the ASN.1 structure then

SEQUENCE {
  INTEGER { 1 }
  OCTET_STRING { `04` }
  [0] {
    # secp384r1
    OBJECT_IDENTIFIER { 1.3.132.0.34 }
  }
}

That's...


short.

@q @cassiopeia More ASN.1 fluff than actual key material. Beautiful.

[cassiopeia@thicc.horse]

@G33KatWork @q i didnt realize these things had such a big spec holy shit

[huronbikes@cyberplace.social]

@q @cassiopeia I saw that the private key had leaked, but that it bakes down to a value of 4 is levels of facepalm I had not anticipated.

[templailloahi@mastodon.social]

@q @cassiopeia No way they just did this.

We need to have a shirt with the DeCSS prime, the eMudhra key, the recent NSA EC seeds…

[catsalad@infosec.exchange]

[flipper@mastodonapp.uk]

@q what 4?

[jbaert@mastodon.social]

@q tiny shirt!

[thesupertechie@lgbtqia.space]

@q A T-Shirt? I'll take 600!

/j, obviously

Though I'd really love shirts with that on it, with no other context.

Better than the CopyLeft DeCSS t-shirts, and fewer characters too. ️
