Doc Text:	The SSL 2.0 support is completely removed from OpenSSL The SSL 2.0 protocol is severally broken and insecure, it was deprecated many years ago and it is not used anymore. Its support was already disabled by default. However to avoid inadvertent reenablement of the insecure protocol its support was removed completely. The OpenSSL library API calls that implement the protocol will permanently return error.

Groups: None (edit)

Description Tomas Mraz 2016-03-23 05:31:27 EDT

We should completely remove the support for SSL 2.0 except for receiving SSLv2 client hellos on the server.

The support will not be compiled into the library. To avoid ABI break the SSL2 specific public functions will be kept but they will return an error.
