nx_rsa_pkcs1_v1_5_sha256_4096_real_test.nx -- REAL RSA-4096 verify against an openssl-generated keypair + signature. Proves the full PKCS1v1.5-SHA256 + RSA-4096 mod-exp + u4096_load_be pipeline shipped this session works end-to-end against bytes produced by a real production toolchain (openssl). No TLS, no X.509, no PEM parsing -- just the load-bearing math + padding. Test fixtures (must exist before running): /tmp/rsa4096_test_n.hex -- 1024-char hex of the 4096-bit modulus + trailing newline /tmp/rsa4096_test_msg.txt -- 23-byte message "hello-rsa4096-substrate" /tmp/rsa4096_test.sig -- 512-byte raw RSA-PKCS1v1.5-SHA256 signature Generated by (host-side): openssl genrsa -out rsa4096_test.key 4096 openssl rsa -in rsa4096_test.key -modulus -noout | sed 's/Modulus=//' \ > rsa4096_test_n.hex echo -n 'hello-rsa4096-substrate' > rsa4096_test_msg.txt openssl dgst -sha256 -sign rsa4096_test.key -out rsa4096_test.sig \ rsa4096_test_msg.txt expect_exit: 0
