See my previous entry, basically you have to:

Allow all ciphers
restrict the root directory on CIPHER key size
put in a 403 error document, this should be in a directory outside the root
with an alias to that directory eg.

ErrorDocument 403 http://url/security/403.html
Alias /security /../errordir

<Directory /rootdir>
SSLRequire %{SSL_CIPHER_USEKEYSIZE} >= 128
</Directory>

Note:
If you have any rewrites these will operate before the key size is checked
unless you put the Rewrites at the directory level.

You should use full URL for the 403 document otherwise Apache does a
redirect to https://url/security/403.html and you could get into a n
infinite loop on the https.

Subject: error page on failure to negotiate ssl connection


We are using server-gated cryptography to mandate 128 bit key strength, but
to also upgrade export browsers.  However, we would like users who do not
have adequate ssl support to see an error page we create rather than
whatever their browser's error message it.

Is there a way to do this with apache+mod_ssl?  I imagine it's a bit of a
chicken-and-egg problem because in order to redirect the user to an error
page, a ssl connection has to be made at the lower cipher strength.

Philip
