[stunnel-users] Stunnel supports ECC certificate?

Thu Jun 3 20:13:48 CEST 2010

I searched the entire archive, couldn't find the answer/solution I am
looking for. I have to post to this group, and appreciate any
help/suggestion from any you.

I use the latest 1.0.0 OpenSSL and 4.33 Stunnel.

I used OpenSSL commands that very similar to what is described in the
following link to create the ECC certificate and the private key file.
http://src.opensolaris.org/source/xref/sfw/usr/src/lib/openssl/openssl-0
.9.8n/demos/ssltest-ecc/ECC-RSAcertgen.sh

Start Stunnel, see the following errors:
Key file: (actual path to the private key file)\HOST.KEY
error stack: 140B3009 : error:140B3009:SSL
routines:SSL_CTX_use_RSAPrivateKey_file:PEM lib
SSL_CTX_use_RSAPrivateKey_file: 607907F: error:0607907F:digital envelope
routines:EVP_PKEY_get1_RSA:expecting an rsa key

There was a similar posting 4-5 years ago, and Mike answered it (the
answer was: Stunnel didn't support ECC at that time).

Seems like this is still true today. Then, when the ECC support will be
added to Stunnel?

If Stunnel already supports ECC certificate, how do I make it work?

Thanks.
