2 @brief lib/tls: TLS library wrappers
4 This module has compatibility wrappers around the library (NSS or OpenSSL,
5 depending on configuration) that Tor uses to implement the TLS link security
8 It also implements the logic for some legacy TLS protocol usage we used to
9 support in old versions of Tor, involving conditional delivery of certificate
10 chains (v1 link protocol) and conditional renegotiation (v2 link protocol).
