RE: Adapting proxo 4.5 to the latest OpenSSL DLLs
I've also been working on patching Proxomitron to work with latest OpenSSL and have success with 1.0.1j, accepts custom cipher configuration and SNI support. Smile!

Here is a brief list of modifications so far, I am still testing it out:
- OpenSSL_add_all_algorithms replaced with SSL_library_init
- Allow configuration of cipher list via SSL_CTX_set_cipher_list (disabled all insecure ciphers)
- SNI support! says
TLS 1.2    Yes
TLS 1.1    Yes*
TLS 1.0    Yes*
SSL 3    Yes*
SSL 2    No

Still todo improvements:
Disable SSLv3 (prevent POODLE attack)
SubjectAltName extension
Wildcard certificates checking

OCSP stapling (after all the above, this one will take quite a bit more code)
