Hi,
I spent more time on this today by looking at the code. I see from
the code that squid does not accept certificates which require
passphrase to read the private key.
In the function readSslPrivateKey(...), I see this
EVP_PKEY *pkey = PEM_read_bio_PrivateKey(bio.get(), NULL,
passwd_callback, NULL);
The passphrase argument is NULL. The certificate file I was
using requires a passphrase to read the keys while the self signed
certificate does not require it and hence it was working.
Am I right in my understanding? Is this the way squid is
designed to work or is this a bug?
Regards,
Prasanna
