If anyone wants to put the eMudhra private key on a T-Shirt:

@q this is horrible, please stop

[elliewithcolor@queer.group]

@q Sticker.

[q@glauca.space]

@dequbed nope, I wont

[dequbed@mastodon.chaosfield.at]

[rampagerslife@girldick.gay]

@q [228] need it on a mug ngl

[q@glauca.space]

@cassiopeia its not a factor of 4, it is 4

[q@glauca.space]

@cassiopeia the curve OID

[hanno@mastodon.social]

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

[q@glauca.space]

@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.

[g33katwork@infosec.exchange]

@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.
