AI Model Claude Solves 25-Year-Old NSA Cryptographic Puzzle
Anthropic's AI model Claude has cracked a long-standing cryptographic mystery involving NSA-provided numbers.
Anthropic's AI model Claude has cracked a long-standing cryptographic mystery involving NSA-provided numbers. JUST (JST) is trading at $0.1354, down 0.1% since this brief published. This is an original TLT brief based on reporting by Cointribune, with live market data added, as of Sat, 17 Oct 2026 23:15:02 UTC.
This development highlights AI's growing potential in solving complex cryptographic problems, potentially impacting cryptographic research and standards. It also addresses longstanding concerns about the security of NIST-standardized elliptic curves.
- Claude solved a 25-year-old cryptographic puzzle in under 30 minutes.
- The solution revealed the origin of five NSA-provided numbers for elliptic curves.
- The numbers came from a 1997-1998 pseudo-random generator, not a backdoor.
- JUST (JST) price remains relatively stable amid the news.
Anthropic's AI model Claude has made a significant breakthrough in cryptography by solving a 25-year-old puzzle in under 30 minutes. The AI was tasked with determining the origin of five numbers provided by the NSA for elliptic curves that were standardized by NIST in 2000.
The longstanding mystery surrounding these numbers stemmed from suspicions that they might conceal a backdoor, which would have posed serious security concerns. However, Claude's analysis revealed that the numbers were generated from an old pseudo-random generator fed by timestamps from 1997 and 1998.
This development underscores the increasing capabilities of AI in tackling complex cryptographic challenges. It also addresses concerns about the integrity of cryptographic standards that have been in use for over two decades.
The broader crypto market remains relatively flat, with a total market cap of $2.79 trillion. 
Bitcoin is down 0.64% in the last 24 hours, and the Fear & Greed index stands at 55, indicating a state of 'Greed' among investors.
JUST (JST), a coin with a market cap of $1.09 billion, has seen a minor 0.23% decrease in the past 24 hours and a 0.95% decline over the last week. The news of Claude's achievement has not had a noticeable impact on JST's price.
Since this brief published about 9 hours ago, JUST (JST) has moved from $0.1356 to $0.1354 — -0.14%.
The chart plots JST's price: grey is the move before this brief published, the vertical dashed line marks the moment it published, the horizontal dashed line is the price then, and the coloured area is the move since — from TLT's market data (daily resolution). It shows what happened after the news, not that the news caused it; many factors move prices. Not financial advice.
At today's peer-to-peer rate, 1 JST ≈ ₦184.82 (about $0.1354), down 0.3% over 24 hours. The naira itself trades about 2.4% above the official rate on the P2P market, so a Nigerian buyer's effective cost differs from the headline dollar price.

AI Model Claude Solves 25-Year-Old NSA Cryptographic Puzzle — questions & answers
What was the origin of the NSA-provided numbers?
The numbers originated from a pseudo-random generator using timestamps from 1997 and 1998.
Did the AI find a backdoor in the elliptic curves?
No, the AI determined that the numbers did not hide a backdoor.
How long did it take for Claude to solve the puzzle?
Claude solved the puzzle in under 30 minutes.
How much is 1 JUST worth in naira today?
About ₦184.82 at the live peer-to-peer (P2P) USDT rate, which is what Nigerians typically trade at — equivalent to roughly $0.1354. The naira price moves with both JST's US-dollar price and the USDT/NGN rate; use our JUST in naira page for any amount.
Has JUST's price moved since this brief was published?
JST is down 0.14% since this brief first published — trading at $0.1354 now versus $0.1356 at publication. TLT re-checks this figure against CoinGecko and Binance every 15 minutes.
