Hello,
after serveral tests (and reading a lot of howto's) I'm now fairly convinced
that the Solaris HW-crypto engine is not automatically used. Even when dovecot
ist compiled with the OpenSSL version provided by Solaris.
Currently I have only a T1-CPU available for testing (Sun Fire T2000) and
after patching src/login-common/ssl-proxy-openssl.c (Dovecot 1.2.17) with
ENGINE *e;
ENGINE_load_builtin_engines(); ENGINE_init((e=ENGINE_by_id("pkcs11")));
Does "openssl engine" return this "pkcs11" string?
ENGINE_set_default_RSA(e); ENGINE_set_default_DSA(e);
ENGINE_set_default_ciphers(e);
in ssl_proxy_init() and inserting ENGINE_cleanup(); in ssl_proxy_deinit()
the crypto device gets used. I'm sure that this is not the whole story since
this only seems to affect the IMAP login.
It should work for POP3 as well, all of the SSL code is shared.
One has to use the specific SSL-engine and the ENGINE/EVP calls (as stated in
the various articles). Is there any chance that Dovecot gets updated/patched
for this ? E.g. Like the SSLCryptoDevice setting in Apache's mod_ssl.
I guess I could add ssl_crypto_device setting for this. But I'll need to
figure out proper ifdefs to avoid compile failures with older OpenSSL
versions.
Just a quick comment -- the Sun instructions for setting up Apache specifically noted the importance
of specifying "SSLCryptoDevice pkcs11" in httpd.conf.
So, the OpenSSL provided by Solaris will do what it should, IFF pkcs11 is specified by the program
that is calling it.
I had an email exchange with a Solaris developer at some point, who said that GnuPG simply could not
use the crypto device, because it was built with libcrypt, did not use the pkcs11 engine, and it
would take a significant rewrite to make it do so.
