Currently util.format is being used for string templating in tls.
By replacing all of the instances of util.format with backtick
string we can remove the need to require util in tls all together.

ALPN is added to tls according to RFC7301, which supersedes NPN.
When the server receives both NPN and ALPN extensions from the client,
ALPN takes precedence over NPN and the server does not send NPN
extension to the client. alpnProtocol in TLSSocket always returns
false when no selected protocol exists by ALPN.
In https server, http/1.1 token is always set when no
options.ALPNProtocols exists.

This adds a new `--tls-cipher-list` command line switch
that can be used to override the built-in default cipher
list. The intent of this is to make it possible to enforce
an alternative default cipher list at the process level.
Overriding the default cipher list is still permitted at
the application level by changing the value of
`require('tls').DEFAULT_CIPHERS`.
As part of the change, the built in default list is moved
out of tls.js and into node_constants.h and node_constants.cc.
Two new constants are added to require('constants'):
* defaultCipherList (the active default cipher list)
* defaultCoreCipherList (the built-in default cipher list)
A test case and doc changes are included.
A new NODE_DEFINE_STRING_CONSTANT macro is also created in
node_internals.h
When node_constants is initialized, it will pick up either
the passed in command line switch or fallback to the default
built-in suite.
Within joyent/node, this change had originaly been wrapped
up with a number of other related commits involving the
removal of the RC4 cipher. This breaks out this isolated
change.

This resolvesjoyent/node#9272. `tlsSocket.getPeerCertificate` will
return an empty object when the peer does not provide a certificate,
but, prior to this, when the certificate is empty, `checkServerIdentity`
would throw because the `subject` wasn't present on the cert.
`checkServerIdentity` must return an error, not throw one, so this
returns an error when the cert is empty instead of throwing
a `TypeError`.

This updates the default cipher suite to an more secure list, which
prefers strong ciphers with Forward Secrecy. Additionally, it enables
`honorCipherOrder` by default.
Noteable effect of this change is that the insecure RC4 ciphers are
disabled and that Chrome negotiates a more secure ECDHE cipher.

Move `createCredentials` to `tls` module and rename it to
`createSecureContext`. Make it use default values from `tls` module:
`DEFAULT_CIPHERS` and `DEFAULT_ECDH_CURVE`.
fix#7249
Split `tls.js` into `_tls_legacy.js`, containing legacy
`createSecurePair` API, and `_tls_wrap.js` containing new code based on
`tls_wrap` binding.
Remove tests that are no longer useful/valid.
1. Emit `sslOutEnd` only when `_internallyPendingBytes() === 0`.
2. Read before checking `._halfRead`, otherwise we'll see only previous
value, and will invoke `._write` callback improperly.
3. Wait for both `end` and `finish` events in `.destroySoon`.
4. Unpipe encrypted stream from socket to prevent write after destroy.
Stream's `._write()` callback should be invoked only after it's opposite
stream has finished processing incoming data, otherwise `finish` event
fires too early and connection might be closed while there's some data
to send to the client.
see #5544
Quote from SSL_shutdown man page:
The output of SSL_get_error(3) may be misleading,
as an erroneous SSL_ERROR_SYSCALL may be flagged even though
no error occurred.
Also, handle all other errors to prevent assertion in `ClearError()`.
When writing bad data to EncryptedStream it'll first get to the
ClientHello parser, and, only after it will refuse it, to the OpenSSL.
But ClientHello parser has limited buffer and therefore write could
return `bytes_written` < `incoming_bytes`, which is not the case when
working with OpenSSL.
After such errors ClientHello parser disables itself and will
pass-through all data to the OpenSSL. So just trying to write data one
more time will throw the rest into OpenSSL and let it handle it.
This saves a few calls to gettimeofday which can be expensive, and
potentially subject to clock drift. Instead use the loop time which
uses hrtime internally.
fixes#5497
Add localAddress and localPort properties to tls.CleartextStream.
Like remoteAddress and localPort, delegate to the backing net.Socket
object.
Refs #5502.
RFC 6125 explicitly states that a client "MUST NOT seek a match
for a reference identifier of CN-ID if the presented identifiers
include a DNS-ID, SRV-ID, URI-ID, or any application-specific
identifier types supported by the client", but it MAY do so if
none of the mentioned identifier types (but others) are present.
The v0.8 Stream.pipe() method automatically destroyed the destination
stream whenever the src stream closed. However, this caused a lot of
problems, and was removed by popular demand. (Many userland modules
still have a no-op destroy() method just because of this.) It was also
very hazardous because this would be done even if { end: false } was
passed in the pipe options.
In v0.10, we decided that the 'close' event and destroy() method are
application-specific, and pipe() doesn't automatically call destroy().
However, TLS actually depended (silently) on this behavior. So, in this
case, we should just go ahead and destroy the thing when close happens.
Closes#5145
Calling `this.pair.encrypted._internallyPendingBytes()` before
handling/resetting error will result in assertion failure:
../src/node_crypto.cc:962: void node::crypto::Connection::ClearError():
Assertion `handle_->Get(String::New("error"))->BooleanValue() == false'
failed.
see #5058
Add the `sessionTimeout` integral value to the list of options
recognized by `tls.createServer`.
This option will be useful for applications which need frequently
establish short-lived TLS connections to the same endpoint. The TLS
tickets RFC is an ideal option to reduce the socket setup overhead
for such scenarios, but the default ticket timeout value (5
minutes) is too low to be useful.
Commit f53441a added crypto.getCiphers() as a function that returns the
names of SSL ciphers.
Commit 14a6c4e then added crypto.getHashes(), which returns the names of
digest algorithms, but that creates a subtle inconsistency: the return
values of crypto.getHashes() are valid arguments to crypto.createHash()
but that is not true for crypto.getCiphers() - the returned values are
only valid for SSL/TLS functions.
Rectify that by adding tls.getCiphers() and making crypto.getCiphers()
return proper cipher names.
This is not a great fix, and it's a bug that's very tricky to reproduce.
Occasionally, while downloading a file, especially on Linux for some
reason, the pause/resume timing will be just right such that the
CryptoStream is in a 'reading' state, but actually has no data, so it
ought to pull more in. Because there's no reads happening, it just sits
there, and the process will exit
This is, fundamentally, a factor of how the HTTP implementation sits
atop CryptoStreams and TCP Socket objects, which is utterly horrible,
and needs to be rewritten. However, in the meantime, npm downloads are
prematurely exiting, causing hard-to-debug "cb() never called!" errors.
