about

nx_u2048.nx -- 2048-bit unsigned big-int (64 × 32-bit limbs). Mirrors nx_u256/nx_u384 with limb count 64. Needed for RSA-2048 signature verification (Task #68, Web PKI legacy RSA roots like Comodo AAA Certificate Services). Layout: 64 i64 slots, low 32 bits used per limb. Limb 0 LSB. Byte serialization: 256-byte BE (DER) layout. Function names use the `u2048_` prefix to avoid the silent- shadowing bug class fixed 2026-05-20 in nx_sha256/nx_sha512. license_tier: INDEPENDENT_REDERIVE genealogy_id: international-research-sources/ietf/rfc_8017 + nist/fips_186_5 lineage_id: nishi_u2048_q10
