Package pbkdf2 implements the key derivation function PBKDF2 as defined in RFC
2898 / PKCS #5 v2.0.
A key derivation function is useful when encrypting data based on a password
or any other not-fully-random data. It uses a pseudorandom function to derive
a secure encryption key based on the password.
While v2.0 of the standard defines only one pseudorandom function to use,
HMAC-SHA1, the drafted v2.1 specification allows use of all five FIPS Approved
Hash Functions SHA-1, SHA-224, SHA-256, SHA-384 and SHA-512 for HMAC. To
choose, you can pass the `New` functions from the different SHA packages to
pbkdf2.Key.

// []byte of length keylen that can be used as cryptographic key. The key is
// derived based on the method described as PBKDF2 with the HMAC variant using
// the supplied hash function.
//
// For example, to use a HMAC-SHA-1 based PBKDF2 key derivation function, you
// can get a derived key for e.g. AES-256 (which needs a 32-byte key) by
// doing:
//
// dk := pbkdf2.Key([]byte("some password"), salt, 4096, 32, sha1.New)
//
// Remember to get a good random salt. At least 8 bytes is recommended by the
// RFC.
//
// Using a higher iteration count will increase the cost of an exhaustive
// search but will also make derivation proportionally slower.

// OAuth2 Configs
//
// Two functions in this package return golang.org/x/oauth2.Config values from Google credential
// data. Google supports two JSON formats for OAuth2 credentials: one is handled by ConfigFromJSON,
// the other by JWTConfigFromJSON. The returned Config can be used to obtain a TokenSource or
// create an http.Client.
//
//
// Credentials
//
// The DefaultCredentials type represents Google Application Default Credentials, as
// well as other forms of credential.
//
// Use FindDefaultCredentials to obtain Application Default Credentials.
// FindDefaultCredentials looks in some well-known places for a credentials file, and
// will call AppEngineTokenSource or ComputeTokenSource as needed.
//
// DefaultClient and DefaultTokenSource are convenience methods. They first call FindDefaultCredentials,
// then use the credentials to construct an http.Client or an oauth2.TokenSource.
//
// Use CredentialsFromJSON to obtain credentials from either of the two JSON
// formats described in OAuth2 Configs, above. (The DefaultCredentials returned may
// not be "Application Default Credentials".) The TokenSource in the returned value
// is the same as the one obtained from the oauth2.Config returned from
// ConfigFromJSON or JWTConfigFromJSON, but the DefaultCredentials may contain
// additional information that is useful is some circumstances.

# Contributing to Go
Go is an open source project.
It is the work of hundreds of contributors. We appreciate your help!
## Filing issues
When [filing an issue](https://golang.org/issue/new), make sure to answer these five questions:
1. What version of Go are you using (`go version`)?
2. What operating system and processor architecture are you using?
3. What did you do?
4. What did you expect to see?
5. What did you see instead?
General questions should go to the [golang-nuts mailing list](https://groups.google.com/group/golang-nuts) instead of the issue tracker.
The gophers there will answer or ask you to file an issue if you've tripped over a bug.
## Contributing code
Please read the [Contribution Guidelines](https://golang.org/doc/contribute.html)
before sending patches.
Unless otherwise noted, the Go source files are distributed under
the BSD-style license found in the LICENSE file.

# Go Sync
This repository provides Go concurrency primitives in addition to the
ones provided by the language and "sync" and "sync/atomic" packages.
## Download/Install
The easiest way to install is to run `go get -u golang.org/x/sync`. You can
also manually git clone the repository to `$GOPATH/src/golang.org/x/sync`.
## Report Issues / Send Patches
This repository uses Gerrit for code changes. To learn how to submit changes to
this repository, see https://golang.org/doc/contribute.html.
The main issue tracker for the sync repository is located at
https://github.com/golang/go/issues. Prefix your issue with "x/sync:" in the
subject line, so it is easy to find.

This program reads a file containing function prototypes

The prototypes are marked by lines beginning with "//sys"
and read like func declarations if //sys is replaced by func, but:
* The parameter lists must give a name for each argument.
This includes return parameters.
* The parameter lists must give a type for each argument:
the (x, y, z int) shorthand is not allowed.
* If the return parameter is an error number, it must be named errno.
A line beginning with //sysnb is like //sys, except that the
goroutine will not be suspended during the execution of the system
call. This must only be used for system calls which can never
block, as otherwise the system call could cause all goroutines to
hang.

# This program reads a file containing function prototypes
# (like syscall_aix.go) and generates system call bodies.
# The prototypes are marked by lines beginning with "//sys"
# and read like func declarations if //sys is replaced by func, but:
# * The parameter lists must give a name for each argument.
# This includes return parameters.
# * The parameter lists must give a type for each argument:
# the (x, y, z int) shorthand is not allowed.
# * If the return parameter is an error number, it must be named err.
# * If go func name needs to be different than its libc name,
# * or the function is not in libc, name could be specified
# * at the end, after "=" sign, like
# //sys getsockopt(s int, level int, name int, val uintptr, vallen *_Socklen) (err error) = libsocket.getsockopt
# This program will generate three files and handle both gc and gccgo implementation:
# - zsyscall_aix_ppc64.go: the common part of each implementation (error handler, pointer creation)
# - zsyscall_aix_ppc64_gc.go: gc part with //go_cgo_import_dynamic and a call to syscall6
# - zsyscall_aix_ppc64_gccgo.go: gccgo part with C function and conversion to C type.
