+# dev.boringcrypto branch
+
+We have been working inside Google on a fork of Go that uses
+BoringCrypto (the core of [BoringSSL](https://boringssl.googlesource.com/boringssl/)) for various crypto primitives, in
+furtherance of some [work related to FIPS 140-2](http://csrc.nist.gov/groups/STM/cmvp/documents/140-1/140sp/140sp2964.pdf). We have heard that
+some external users of Go would be interested in this code as well, so
+I intend to create a new branch dev.boringcrypto that will hold
+patches to make Go use BoringCrypto.
+
+Unlike typical dev branches, we do not intend any eventual merge of
+this code into the master branch. Instead we intend to maintain in
+that branch the latest release plus BoringCrypto patches. In this
+sense it is a bit like dev.typealias holding go1.8+type alias patches.
+
+To be clear, we are not making any statements or representations about
+the suitability of this code in relation to the FIPS 140-2 standard.
+Interested users will have to evaluate for themselves whether the code
+is useful for their own purposes.

+# README.md
+
+This directory holds build scripts for unofficial, unsupported
+distributions of Go+BoringCrypto.
+
+## Version strings
+
+The distribution name for a Go+BoringCrypto release has the form `<GoVersion>b<BoringCryptoVersion>`,
+where `<GoVersion>` is the Go version the release is based on, and `<BoringCryptoVersion>` is
+an integer that increments each time there is a new release with different BoringCrypto bits.
+The `<BoringCryptoVersion>` is stored in the `VERSION` file in this directory.
+
+For example, the first release is based on Go 1.8.3 is `go1.8.3b1`.
+If the BoringCrypto bits are updated, the next would be `go1.8.3b2`.
+If, after that, Go 1.9 is released and the same BoringCrypto code added to it,
+that would result in `go1.9b2`. There would likely not be a `go1.9b1`,
+since that would indicate Go 1.9 with the older BoringCrypto code.
+
+## Releases
+
+The `build.release` script prepares a binary release and publishes it in Google Cloud Storage
+at `gs://go-boringcrypto/`, making it available for download at
+`https://go-boringcrypto.storage.googleapis.com/<FILE>`.
+The script records each published release in the `RELEASES` file in this directory.
+
+The `build.docker` script, which must be run after `build.release`, prepares a Docker image
+and publishes it on hub.docker.com in the goboring organization.
+`go1.8.3b1` is published as `goboring/golang:1.8.3b1`.
+
+## Release process
+
+Development is done on the dev.boringcrypto branch, which tracks
+master. Releases are cut from dev.boringcrypto.go1.X branches,
+which are BoringCrypto backported to the Go 1.X release branches.
+To issue new BoringCrypto releases based on Go 1.X:
+
+1. If the BoringCrypto bits have been updated, increment the
+   number in `VERSION`, send that change out as a CL for review,
+   get it committed to dev.boringcrypto, and run `git sync`.
+
+2. Change to the dev.boringcrypto.go1.X branch and cherry-pick
+   all BoringCrypto updates, including the update of the
+   `VERSION` file. If desired, merge release-branch.go1.X into
+   dev.boringcrypto.go1.X. Mail them out and get them committed.
+
+3. **Back on the dev.boringcrypto branch**, run `git fetch`,
+   `make.bash` and then `build.release dev.boringcrypto.go1.X`.
+   The script will determine the base Go version and the
+   BoringCrypto version, build a release, and upload it.
+
+4. Run `build.docker`, which will build and upload a Docker image
+   from the latest release.
+
+5. Send out a CL with the updated `RELEASES` file and get it
+   committed to dev.boringcrypto.
+
+## Building from Docker
+
+A Dockerfile that starts with `FROM golang:1.8.3` can switch
+to `FROM goboring/golang:1.8.3b2` (see [goboring/golang on Docker Hub](https://hub.docker.com/r/goboring/golang/))
+and should need no other modifications.
+
+## Building from Bazel
+
+Starting from [bazelbuild/rules_go](https://github.com/bazelbuild/rules_go)
+tag 0.7.1, simply download the BoringCrypto-enabled Go SDK using
+`go_download_sdk()` before calling `go_register_toolchains()`.
+
+For example, to use Go 1.9.3 with BoringCrypto on Linux, use the following lines
+in `WORKSPACE`:
+```python
+load("@io_bazel_rules_go//go:def.bzl", "go_rules_dependencies", "go_download_sdk", "go_register_toolchains")
+
+go_rules_dependencies()
+
+go_download_sdk(
+    name = "go_sdk",
+    sdks = {
+       "linux_amd64": ("go1.9.3b4.linux-amd64.tar.gz", "db1997b2454a2f27669b849d2d2cafb247a55128d53da678f06cb409310d6660"),
+    },
+    urls = ["https://storage.googleapis.com/go-boringcrypto/{}"],
+)
+
+go_register_toolchains()
+```
+
+**Note**: you must *not* enable `pure` mode, since cgo must be enabled. To
+ensure that binaries are linked with BoringCrypto, you can set `pure = "off"` on
+all relevant `go_binary` rules.
+
+## Caveat
+
+BoringCrypto is used for a given build only in limited circumstances:
+
+  - The build must be GOOS=linux, GOARCH=amd64.
+  - The build must have cgo enabled.
+  - The android build tag must not be specified.
+  - The cmd_go_bootstrap build tag must not be specified.
+
+The version string reported by `runtime.Version` does not indicate that BoringCrypto
+was actually used for the build. For example, linux/386 and non-cgo linux/amd64 binaries
+will report a version of `go1.8.3b2` but not be using BoringCrypto.
+
+To check whether a given binary is using BoringCrypto, run `go tool nm` on it and check
+that it has symbols named `*_Cfunc__goboringcrypto_*`.
+
+The program [rsc.io/goversion](https://godoc.org/rsc.io/goversion) will report the
+crypto implementation used by a given binary when invoked with the `-crypto` flag.
