GnuTLS

Transport Level Security for Julia Streams provided by GnuTLS

Readme

GnuTLS.jl

Add transport layer security (TLS) to any Julia Stream

Build Status Coverage Status

GnuTLS GnuTLS

Installation: Pkg.add("GnuTLS")

API

GnuTLS.jl can add TLS support to any transport layer implementing the Julia IOinterface (e.g. IOStream, TcpSocket, NamedPipe, TTY, ...)

The following functions are currently provided:

  • GnuTLS.Session()

    Create a new SSL/TLS session. After initialization this object becomes a valid Julia IO object and may be used as such.

    NOTE: This method is not exported by default and should be used as GnuTLS.Session

  • GnuTLS.CertificateStore()

    Initialize an empty certificate store. Support for authentication is incomplete in the current version.

    NOTE: This method is not exported by default and should be used as GnuTLS.CertificateStore

  • set_credentials!(s::Session,c::CertificateStore)

    Associates the CertificateStore c with the session s. The certificate from the server will be stored here and may later be validated before processing further requests.

  • set_priority_string!(s::Session,priority::ASCIIString="NORMAL")

    Set the GnuTLS priority string, used to determine which protocol versions to support. For a full list of supported options, see the GnuTLS manual.

  • associate_stream{S<:IO,T<:IO}(s::Session, read::S, write::T=read)

    Set the transport layer for the current session.

  • handshake!(s::Session)

    Perform the SSL/TLS handshake. On success the Session becomes active and may be used like any other streaming IO object.

  • init()

    Initialize the GnuTLS library. This function is automatically called when the package is loaded and thus you should rarely have to call it yourself.

  • deinit()

    Undo init and free all associated resources.

Usage

The following code snippet demonstrates how the GnuTLS.jl package may be used to query an HTTPS resource:

using GnuTLS
sess = GnuTLS.Session()
set_priority_string!(sess)
set_credentials!(sess,GnuTLS.CertificateStore())
associate_stream(sess,connect("github.com",443))
handshake!(sess)
write(sess,"GET / HTTP/1.1\r\n\r\n")
print(readall(sess))
