Pion DTLS

A Go implementation of DTLS

Pion DTLS Sourcegraph Widget Slack Widget
GitHub Workflow Status Go Reference Coverage Status Go Report Card License: MIT


Native DTLS 1.2 implementation in the Go programming language.

A long term goal is a professional security review, and maybe an inclusion in stdlib.

RFCs

Implemented

Goals/Progress

This will only be targeting DTLS 1.2, and the most modern/common cipher suites. We would love contributions that fall under the 'Planned Features' and any bug fixes!

Current features

  • DTLS 1.2 Client/Server
  • Key Exchange via ECDHE(curve25519, nistp256, nistp384) and PSK
  • Packet loss and re-ordering is handled during handshaking
  • Key export (RFC 5705)
  • Serialization and Resumption of sessions
  • Extended Master Secret extension (RFC 7627)
  • ALPN extension (RFC 7301)

Supported ciphers

ECDHE
  • TLS_ECDHE_ECDSA_WITH_AES_128_CCM (RFC 6655)
  • TLS_ECDHE_ECDSA_WITH_AES_128_CCM_8 (RFC 6655)
  • TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256 (RFC 5289)
  • TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256 (RFC 5289)
  • TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384 (RFC 5289)
  • TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384 (RFC 5289)
  • TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA (RFC 8422)
  • TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA (RFC 8422)
PSK
ECDHE & PSK
  • TLS_ECDHE_PSK_WITH_AES_128_CBC_SHA256 (RFC 5489)

Planned Features

  • Chacha20Poly1305

Excluded Features

  • DTLS 1.0
  • Renegotiation
  • Compression

Using

This library needs at least Go 1.13, and you should have Go modules enabled.

Pion DTLS

For a DTLS 1.2 Server that listens on 127.0.0.1:4444

go run examples/listen/selfsign/main.go

For a DTLS 1.2 Client that connects to 127.0.0.1:4444

go run examples/dial/selfsign/main.go

OpenSSL

Pion DTLS can connect to itself and OpenSSL.

  // Generate a certificate
  openssl ecparam -out key.pem -name prime256v1 -genkey
  openssl req -new -sha256 -key key.pem -out server.csr
  openssl x509 -req -sha256 -days 365 -in server.csr -signkey key.pem -out cert.pem

  // Use with examples/dial/selfsign/main.go
  openssl s_server -dtls1_2 -cert cert.pem -key key.pem -accept 4444

  // Use with examples/listen/selfsign/main.go
  openssl s_client -dtls1_2 -connect 127.0.0.1:4444 -debug -cert cert.pem -key key.pem

Using with PSK

Pion DTLS also comes with examples that do key exchange via PSK

Pion DTLS

go run examples/listen/psk/main.go
go run examples/dial/psk/main.go

OpenSSL

  // Use with examples/dial/psk/main.go
  openssl s_server -dtls1_2 -accept 4444 -nocert -psk abc123 -cipher PSK-AES128-CCM8

  // Use with examples/listen/psk/main.go
  openssl s_client -dtls1_2 -connect 127.0.0.1:4444 -psk abc123 -cipher PSK-AES128-CCM8
