SMTP certificate

Question

I test subEthaSMTP SMTP server. Everything is OK, but I want use SSL/TLS. I read the article about this and have a question.

I have csr, crt and key file, but into article used to PKCS12 , JKS, and SunX509.

Is it possible use csr, crt and key or how to convert it into need format.

P.S. Sorry I am not expert in Java.

Answer 1

The CSR is a Certificate Sign Request. You should already self-sign the certificate or send to a certicate authority. If you are lost in this point, read the certificates howto.

Then you should have a CRT file (The CRT is a X.509 certificate in DER format) self-signed or signed by a Certificate authority, to create a PKCS#12 certificate you should:

1. Transform the DER certificate to PEM.
2. Mix PEM and KEY private key file into the PKCS#12 fileformat.

The openssl commands are here in "Converting Using OpenSSL" section.

This stuff is not Java, It's just SSL/TLS.
