AI advancements in cryptographic problem solving

Overview

Recent developments indicate that AI models, specifically Anthropic’s Claude, are increasingly capable of solving complex cryptographic challenges.

In September 2026, researcher Steve Weis used Claude AI to factor the RSA-896 semiprime, a 270-decimal-digit number. By utilizing the General Number Field Sieve (GNFS) algorithm optimized through AI to manage GPU computations, Weis set a new public factoring record. While experts state this does not yet compromise the RSA-2048 standard, it suggests that RSA-1024 keys may be vulnerable to entities with sufficient GPU resources.

By October 2026, Claude AI was used to resolve a 25-year-old mystery concerning the origin of cryptographic seeds used in several NIST-standardized elliptic curves. The AI identified in under 30 minutes that the seeds used by the NSA for curves such as P-256 and P-384 were generated via the lrand48 pseudo-random number generator from a 1990s C library.

Research released on October 16, 2026, specifies that the seeds for curves P-192, P-224, P-256, P-384, and P-521 were initialized with Unix timestamps between May 1997 and April 1998. The model recognized a pattern where lrand48 outputs only 31 bits, resulting in systematic zero bits in the seeds. While the discovery does not expose immediate security vulnerabilities or provide a method to break existing encryption, it provides reproducible evidence that reduces long-standing suspicions of intentional mathematical backdoors. Anthropic donated the associated $36,864 bounty to the Internet Security Research Group.
