HDSSL_COMP_add_compression_method.pod5 …mpression_method, SSL_COMP_free_compression_methods - handle SSL/TLS integrated compression methods
17 SSL_COMP_add_compression_method() adds the compression method B<cm> with
18 the identifier B<id> to the list of available compression methods. This

28 The TLS standard (or SSLv3) allows the integration of compression methods
29 into the communication. The TLS RFC does however not specify compression
31 way to integrate compression with unknown peers. It is therefore currently not
32 recommended to integrate compression into applications. Applications for
33 non-public use may agree on certain compression methods. Using different
34 compression methods with the same identifier will lead to connection failure.
