Liberal Go TLS + X.509 Library for Research

 ZCrypto contains specialized versions of tls and x509. It is primarily
 based on Golang's TLS library
 (https://github.com/golang/go/blob/master/src/crypto/tls)
 .
 Important note:
 .
 ZCrypto is a research library, designed to be used for data collection
 and analysis, as well as experimenting and prototyping. It should not be used
 to provide security for production systems!
 .
 This package includes:
  - zcrypto/tls (formerly known as ZTLS): A research TLS library based on Golang
  standard library crypto/tls that contains that speaks old TLS versions, export
  ciphers, logs handshake messages, and is highly configurable. Many scary parts
  are exposed as public variables. It is primarily used for data collection
  - zcrypto/x509 A fork of the Golang stdlib crypto/x509 that adds the ability
  to serialize certificates to JSON, and plays nice with CT.
  - zcrypto/ct A fork of the Google Certificate Transparency Golang library,
  designed to play nice with ZCrypto.
