Ok, desmontando meu eCNPJ eu identifiquei 3 certificados que estão no zip deste shell.
- AC_Certisign_RFB_G5.crt
- AC_Secretaria_da_Receita_Federal_do_Brasil_v4.crt
- ICP-Brasilv5.crt
O trecho abaixo faz o Nginx funcionar direitinho
cat /etc/ssl/certs/icp-brasil/{AC_Certisign_RFB_G5.crt,AC_Secretaria_da_Receita_Federal_do_Brasil_v4.crt,ICP-Brasilv5.crt} > chain.pem
nas confs do nginx, tenho
ssl_client_certificate /etc/nginx/client-certs/chain.pem;
ssl_verify_client on;
ssl_verify_depth 2;
Entendi que ssl_verify_depth vai fazer o Nginx verificar os certificados intermediarios no chain.pem, mas honestamente, ainda não li a documentação oficial. https://stackoverflow.com/questions/8431528/nginx-ssl-certificate-authentication-signed-by-intermediate-ca-chain

file *.crt|grep data|sed 's/: *data//'
que está na linha 15 não retorna resultados. Além disso, o bundle fica tão grande que o nginx exibe a mensagem abaixo nos logsQuais certificados fariam o Nginx aceitar um e-CNPJ A1 ?
