enable

Enable/disable cryptography on the stream.

crypto_type

Setup encryption on the stream. Valid methods are

  • STREAM_CRYPTO_METHOD_SSLv2_CLIENT
  • STREAM_CRYPTO_METHOD_SSLv3_CLIENT
  • STREAM_CRYPTO_METHOD_SSLv23_CLIENT
  • STREAM_CRYPTO_METHOD_ANY_CLIENT
  • STREAM_CRYPTO_METHOD_TLS_CLIENT
  • STREAM_CRYPTO_METHOD_TLSv1_0_CLIENT
  • STREAM_CRYPTO_METHOD_TLSv1_1_CLIENT
  • STREAM_CRYPTO_METHOD_TLSv1_2_CLIENT
  • STREAM_CRYPTO_METHOD_SSLv2_SERVER
  • STREAM_CRYPTO_METHOD_SSLv3_SERVER
  • STREAM_CRYPTO_METHOD_SSLv23_SERVER
  • STREAM_CRYPTO_METHOD_ANY_SERVER
  • STREAM_CRYPTO_METHOD_TLS_SERVER
  • STREAM_CRYPTO_METHOD_TLSv1_0_SERVER
  • STREAM_CRYPTO_METHOD_TLSv1_1_SERVER
  • STREAM_CRYPTO_METHOD_TLSv1_2_SERVER

If omitted, the crypto_type context option on the stream's SSL context will be used instead.
