Use compression

SSL-enabled classes in SecureBlackbox support TLS compression using DEFLATE method, as defined by RFC 3749.

To enable compression, use CompressionAlgorithms property of SSL-enabled classes.

Note, that compression is an addition to TLS 1.0 and is not supported by most SSL clients and servers. SecureBlackbox supports compression in application-level protocols, such as HTTP (in TElHTTPSClient) and FTPS (Mode Z in TElSimpleFTPSClient).
