We use the standard Apache 2.0 file header, described in "APPENDIX: How to apply the Apache License to your work." This was primarily automated by running: git ls-tree -r --name-only HEAD | xargs go run ./util/relicense.go See go/boringssl-relicensing-triage for the results of triaging the output of the tool. As part of this, switch from taking fiat-crypto under MIT license to Apache 2.0. (It is licensed under MIT OR Apache-2.0 OR BSD-1-Clause.) The copyright_summary tool can also be used to confirm we didn't accidentally drop any copyright lines: # Run before the CL git grep -l Copyright | xargs go run ./util/copyright_summary.go -out /tmp/old.json # Run after the CL git grep -l Copyright | xargs go run ./util/copyright_summary.go -compare /tmp/old.json Bug: 364634028 Change-Id: I17c50e761e9d077a1f92e25969e50ed35e320c59 Reviewed-on: https://boringssl-review.googlesource.com/c/boringssl/+/75852 Reviewed-by: Bob Beck <bbe@google.com> Commit-Queue: David Benjamin <davidben@google.com> Reviewed-by: Adam Langley <agl@google.com>
