Subject RE: My web application to use SSL (JSSE - RSA)
Date Fri, 10 Jun 2011 20:46:08 GMT
We switched from JSSE to the APR and OpenSSL about 6 months.  We
converted all existing keys and certs to the format required by OpenSSL.
It was not hard.  Some people say it can't be done, but they're wrong.
After 6 months with openSSL, I say it's easier to use than JSSE.  We use
not only server-side certs, we also require client certificate
authentication and perform certificate revocation checking.

APR+SSL is a little faster, if I remember correctly, Chris?

No.

Yes.
