Parameters
- stream
-
The stream resource.
- enable
-
Enable/disable cryptography on the stream.
- crypto_method

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_method context option on the stream's SSL context will be used instead.

-
Seed the stream with settings from session_stream.
Return Values
