Package tls partially implements TLS 1. CipherSuiteName returns the standard name for the passed cipher suite ID e. Listen creates a TLS listener accepting connections on the given network address using net. The configuration config must be non-nil and must include at least one certificate or else set GetCertificate. NewListener creates a Listener which accepts connections from an inner Listener and wraps each connection with Server. The files must contain PEM encoded data.

The certificate file may contain intermediate certificates following the leaf certificate to form a certificate chain. On successful return, Certificate. Leaf will be nil because the parsed form of the certificate is not retained. CertificateRequestInfo contains information from a server's CertificateRequest message, which is used to demand a certificate and proof of control from a client. SupportsCertificate returns nil if the provided certificate is supported by the server that sent the CertificateRequest.

Otherwise, it returns an error describing the reason for the incompatibility.

CipherSuite is a TLS cipher suite. Note that most functions in this package accept and expose cipher suite IDs instead of this type.

CipherSuites returns a list of cipher suites currently implemented by this package, excluding those with security issues, which are returned by InsecureCipherSuites. The list is sorted by ID. Note that the default cipher suites selected by this package might depend on logic that can't be captured by a static list.

InsecureCipherSuites returns a list of cipher suites currently implemented by this package and which have security issues. Most applications should not use the cipher suites in this list, and should only use those returned by CipherSuites.

SupportsCertificate returns nil if the provided certificate is supported by the client that sent the ClientHello. Note that if GetConfigForClient returns a different Config, the change can't be accounted for by this method.For control over proxies, TLS configuration, keep-alives, compression, and other settings, create a Transport:.

Clients and Transports are safe for concurrent use by multiple goroutines and for efficiency should only be created once and re-used. The handler is usually nil, which means to use DefaultServeMux. Starting with Go 1. TLSNextProto for servers to a non-nil, empty map. This can be overridden by setting Server. It is like time. The time being formatted must be in UTC for Format to generate the correct format. TrailerPrefix is a magic prefix for ResponseWriter. Header map keys that, if present, signals that the map entry is actually for the response trailers, and not the response headers.

This mechanism is intended only for trailers that are not known prior to the headers being written. If the set of trailers is fixed or known before the header is written, the normal Go trailers mechanism is preferred:. ErrAbortHandler is a sentinel panic value to abort a handler.

While any panic from ServeHTTP aborts the response to the client, panicking with ErrAbortHandler also suppresses logging of a stack trace to the server's error log. ErrLineTooLong is returned when reading request or response bodies with malformed chunked encoding. ErrMissingFile is returned by FormFile when the provided file field name is either not present in the request or not a file field. ErrUseLastResponse can be returned by Client.

CheckRedirect hooks to control how redirects are processed. If returned, the next request is not sent and the most recent response is returned with its body unclosed.

NoBody is an io. ReadCloser with no bytes. Read always returns EOF and Close always returns nil. It can be used in an outgoing client request to explicitly signal that a request has zero bytes.

An alternative, however, is to simply set Request. Body to nil. CanonicalHeaderKey returns the canonical format of the header key s. The canonicalization converts the first letter and any letter following a hyphen to upper case; the rest are converted to lowercase. For example, the canonical key for "accept-encoding" is "Accept-Encoding". If s contains a space or invalid header field bytes, it is returned without modifications.

It considers at most the first bytes of data. Error replies to the request with the specified error message and HTTP code. It does not otherwise end the request; the caller should ensure no further writes are done to w.

The error message should be plain text. Handle registers the handler for the given pattern in the DefaultServeMux. The documentation for ServeMux explains how patterns are matched.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

The documentation should reflect the best practice how to initialize tls. This is somewhat similar to ? If possible, provide a recipe for reproducing the error. A complete runnable program is good. A link on play. I can reproduce this if I don't set the transport for the client, which uses the default transport. CC bradfitz? MaxIdleConns etc.

I've been bitten by getting default zero values following the example, as zero value is different from ones from DefaultTransport.

Two DES-based cipher suites are enabled by default.

This is flagged as vulnerable to the Sweet32 attack. Or, if there are other reasons that this is not a concern in Go's implementation, this should be documented to put our users' minds at ease. We can use the tls. CipherSuites option to disable the DES-based ciphers ourselves, but we'd prefer to delegate the knowledge of which ciphers are safe to the Go crypto team.

Are you suggesting that setting the MinVersion should also change the default cipher suites? Both of these seem rather surprising cross-behaviours. As you note, if you wish to disable cipher suites you are able to. Also, keep in mind that disabling 3DES does not improve the first-order security of the system—it just breaks clients that cannot do better.

That might lead to helpful second-order effects e. I would prefer to disable 3DES by default.

That's simple and clear. At some point the balance will shift and they'll have to explicitly enable 3DES rather than the other set explicitly disabling it. I don't know whether 1. The Mozilla wiki has a good list of CipherSuites and compatibility with various browsers.

Yes, that's my suggestion. They are now deprecated and will be documented in a separate document. If there's no precedent for this sort of "cross-behavior", though, I can see why you might be reluctant to introduce it. So in that case should the report from Nessus that this configuration is vulnerable to Sweet32 be regarded as a false positive? What I'm really looking for is an answer to "i'm willing to abandon browsers older than X; what is the most secure way to configure my TLS server? I was hoping that setting MinVersion to 1.

Maybe there should be a package probably outside the standard library so it can update on its own schedule containing factory functions that construct tls. Configs from higher-level parameters like Python's ssl. It means single-DES. It's technically true, but the implications are perhaps non-obvious. It's not the case that the whole user population is vulnerable because 3DES is enabled.

Rather, users who otherwise couldn't connect can do so, but only with 3DES, and that means that they'll be subject to birthday-bound limitations inherent with any bit cipher. As linked above, there are several resources that have opinions on how you should configure TLS servers.

But the MinVersion controls the minimum version and I think it would be unwise for these low-level controls to have non-obvious effects, like also changing the cipher list.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

It seems that the hostname verification is enabled by setting tls. Did I get that right? It seems non-obvious that tls. ServerName only controlled SNI.
