== NTBTLS `//Not Too Bad TLS//` is a TLS client-only library developed by Werner Koch. * It started (2014) as a stripped down fork of PolarSSL (now called mbed tls), * using libgcrypt and existing GnuPG modules for X.509 certificate handling. Status: **20160913: pre-alpha** https://git.gnupg.org/cgi-bin/gitweb.cgi?p=ntbtls.git;a=summary === Rationale TLS client connections are needed in GnuPG for transport of certificate, pubkeys and revocation information. Using gnutls, mbed_tls or a different TLS library would introduce additional crypto code which makes the whole system harder to evaluate. GnuPG already has a number of the required technical functionality.
