Bounty to Recover NIST’s Elliptic Curve Seeds

This is a fun challenge:

The NIST elliptic curves that power much of modern cryptography were generated in the late ’90s by hashing seeds provided by the NSA. How were the seeds generated? Rumor has it that they are in turn hashes of English sentences, but the person who picked them, Dr. Jerry Solinas, passed away in early 2023 leaving behind a cryptographic mystery, some conspiracy theories, and an historical password cracking challenge.

So there’s a $12K prize to recover the hash seeds.

Some backstory:

Some of the backstory here (it’s the funniest fucking backstory ever): it’s lately been circulating—though I think this may have been somewhat common knowledge among practitioners, though definitely not to me—that the “random” seeds for the NIST P-curves, generated in the 1990s by Jerry Solinas at NSA, were simply SHA1 hashes of some variation of the string “Give Jerry a raise”…

What’d be the best way to find out how to decrypt/un-encode parts of ciphertext? [closed]

I have been set on a mission by a friend to try and find a way to decrypt any/all of these strings:

Bypassing AES encryption if the keys are not in local,but in server

When I conduct a mobile pentest, I have run into payload encryption in HTTP traffic. In general, the AES key and IV ( initialization vector) are located in APK, and can be used to encrypt the payload using Burp suite extensions such as AES… Continue reading Bypassing AES encryption if the keys are not in local,but in server

New Revelations from the Snowden Documents

Jake Appelbaum’s PhD thesis contains several new revelations from the classified NSA documents provided to journalists by Edward Snowden. Nothing major, but a few more tidbits.
Kind of amazing that that all happened ten years ago. At this point, … Continue reading New Revelations from the Snowden Documents
