I can only speculate because I haven't really tested it. Given that this
is a string for legacy servers, and SSL 3.0 originally only supported
ARCFOUR and 3DES, you could have an issue with servers that only support
3DES. I've not seen such a server so far (although I've seen many
servers that only support ARCFOUR).
