Setting Safari SSL/TLS Cipher Suites Does anyone know how to set the priority order of SSL/TLS cipher suites on Safari for Mac OSX (10.7 ideally, but any version would be helpful). Can't seem to find any documentation on that point.
Unfortunately, AFAIK, this setting does not exist. (It doesn't exist in another WebKit browser, either: Google Chrome. You can do this in Firefox, though, using 'about:config'.)

About hard-coded cipher priorities/support for the SSL/TLS handshake:

I tested that Safari does not support 40-bit RC4 encryption with an MD5 hash. This means that it does not support some products that are required by US export law to use low (&lt;64-bit) encryption.

"Initially, in SSL/TLS negotiations, TLS with RSA and weak 128-bit RC4 keys are offered first and second in the cipher order. Worse, ECC (Elliptical Curve Cryptography), AES (Advanced Encryption Standard), and 256-bit keys are never offered as potential cipher choices; further, MD5 is offered first and more frequently than SHA-1, when it should be the other way around."
