Unfortunately, this included hyperlinks. Unbreak the hyperlinks like this: find . -name \*.go | xargs sed -i s%https://github.com/rfjakob/gocryptfs/v2/%https://github.com/rfjakob/gocryptfs/v2/% go mod: declare module version v2 2021-08-23T13:05:15+00:00 Jakob Unterwurzacher 2021-08-23T13:05:15+00:00 urn:sha1:69d88505fd7f4cb0d9e4f1918de296342fe05858 Our git version is v2+ for some time now, but go.mod still declared v1. Hopefully making both match makes https://pkg.go.dev/github.com/rfjakob/gocryptfs/v2 work. All the import paths have been fixed like this: find . -name \*.go | xargs sed -i s%github.com/rfjakob/gocryptfs/%github.com/rfjakob/gocryptfs/v2/% stupidgcm: prefer Go stdlib over OpenSSL on Apple M1 2021-05-26T07:20:22+00:00 Jakob Unterwurzacher 2021-05-26T07:20:22+00:00 urn:sha1:1d2ac1e589209be96f8ee5fbba9a18e7e2c5fb04 https://github.com/rfjakob/gocryptfs/issues/556 Prefer Go stdlib aes-gcm on arm64 with aes instructions 2020-04-13T20:34:07+00:00 Jakob Unterwurzacher 2020-04-13T20:34:07+00:00 urn:sha1:8f5c2a613d37d8f58aee5b2405098da5c99aaca2 We used to prefer openssl in this situation, which used to make sense, but now Go gained an optimized assembly implementation for aes-gcm on arm64 with aes instructions: root@q1:~/go/src/github.com/rfjakob/gocryptfs# ./gocryptfs -speed gocryptfs v1.7.1-46-g73436d9; go-fuse v1.0.1-0.20190319092520-161a16484456; 2020-04-13 go1.14.2 linux/arm64 AES-GCM-256-OpenSSL 212.30 MB/s (selected in auto mode) AES-GCM-256-Go 452.30 MB/s AES-SIV-512-Go 100.25 MB/s XChaCha20-Poly1305-Go 137.35 MB/s https://github.com/rfjakob/gocryptfs/issues/452 merge prefer_openssl package into stupidgcm 2020-02-15T16:21:30+00:00 Jakob Unterwurzacher 2020-02-15T16:21:30+00:00 urn:sha1:d5ce340c02601992cc9dab1bd7d3c2d95d81155e Now that I have discovered golang.org/x/sys/cpu and that Go versions below 1.6 are uncommon, there was not much useful code left in prefer_openssl. Merge the remains into stupidgcm.
