Claude reveals ECDSA curve origins

Claude reportedly found that the seeds for five NIST prime curves (P-192, P-224, P-256, P-384 and P-521) were not hash outputs but came from the C library's lrand48 random-number generator initialized with a Unix timestamp. The article says this was found in under half an hour, after Claude searched for patterns in the seeds rather than the humorous passphrase rumored to have been used. The article states this is not a cryptographic break or weakness, and that the simple generation method leaves less room for hidden backdoors. It also says the base points of six curves came from FreeLIP's random number generator, while the origins of the P-224, P-256, P-384, P-521 base points and one binary seed remain unexplained.
