Então, tentei encontrar a resposta no Google ou nas man pages, mas procurar o significado de um identificador que parece uma letra parece ser impossível.

Se eu executar o seguinte: 

openssl s_client -connect google.ca:443 -showcerts

Eu entendo isso: 

 2 s:/C=US/O=GeoTrust Inc./CN=GeoTrust Global CA
   i:/C=US/O=Equifax/OU=Equifax Secure Certificate Authority

O que significa s / i?

Each certificate is presented as a Subject and an Issuer. The Subject is the thing the certificate is supposed to represent, and the Issuer is the issuing Certificate Authority.

  • s significa Assunto
  • i significa Emissor .

Certificate Subject and Issuer

Each certificate is presented as a Subject and an Issuer. The Subject is the thing the certificate is supposed to represent, and the Issuer is the issuing Certificate Authority. For example here’s certificate 0 (the server certificate) from this chain:

 0 s:/1.3.6.1.4.1.311.60.2.1.3=US/1.3.6.1.4.1.311.60.2.1.2=
     Washington/businessCategory=Private Organization/serialNumber=
     600413485/C=US/postalCode=98052/ST=Washington/L=Redmond/
     street=1 Microsoft Way/O=Microsoft Corporation/OU=MSCOM
     /CN=www.microsoft.com
   i:/C=US/O=Symantec Corporation/OU=Symantec Trust Network
     /CN=Symantec Class 3 EV SSL CA - G3

You can see the certificate number (zero) then s: meaning Subject: and i: meaning Issuer. It follows then that the Issuer of certificate 0 should be the Subject of certificate 1, as we want to verify if the Issuer is valid; and so it is:

 1 s:/C=US/O=Symantec Corporation/OU=Symantec Trust Network
     /CN=Symantec Class 3 EV SSL CA - G3
   i:/C=US/O=VeriSign, Inc./OU=VeriSign Trust Network/OU=(c) 2006
     VeriSign, Inc. - For authorized use only/CN=VeriSign Class 3
     Public Primary Certification Authority - G5
