2021-09-07speed: add bEncrypt helper, reuse dst bufferJakob Unterwurzacher
The bEncrypt helper massively deduplicates the code, and reusing the dst buffer gives higher performance, and that's what gocryptfs does in normal operation via sync.Pool. $ benchstat old.txt new.txt name old time/op new time/op delta StupidGCM-4 6.24µs ± 1% 4.65µs ± 0% -25.47% (p=0.008 n=5+5) GoGCM-4 4.90µs ± 0% 4.10µs ± 0% -16.44% (p=0.008 n=5+5) AESSIV-4 26.4µs ± 0% 25.6µs ± 0% -2.90% (p=0.008 n=5+5) Xchacha-4 5.76µs ± 0% 4.91µs ± 0% -14.79% (p=0.008 n=5+5) StupidXchacha-4 7.24µs ± 1% 5.48µs ± 0% -24.33% (p=0.008 n=5+5) name old speed new speed delta StupidGCM-4 656MB/s ± 1% 880MB/s ± 0% +34.15% (p=0.008 n=5+5) GoGCM-4 835MB/s ± 0% 1000MB/s ± 0% +19.68% (p=0.008 n=5+5) AESSIV-4 155MB/s ± 0% 160MB/s ± 0% +2.99% (p=0.008 n=5+5) Xchacha-4 711MB/s ± 0% 834MB/s ± 0% +17.35% (p=0.008 n=5+5) StupidXchacha-4 565MB/s ± 1% 747MB/s ± 0% +32.15% (p=0.008 n=5+5)

2021-08-23speed: use algo names from cryptocoreJakob Unterwurzacher
2021-08-23go mod: declare module version v2Jakob Unterwurzacher
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/%
2021-05-18-speed: note that XChaCha20 is not selectableJakob Unterwurzacher
This is unclear to users, as seen on https://github.com/rfjakob/gocryptfs/issues/452#issuecomment-828836651

2020-02-15merge prefer_openssl package into stupidgcmJakob Unterwurzacher
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.
2017-04-29fix golint complaintsJakob Unterwurzacher
2017-04-23Add -forcedecodedanim7
Force decode of encrypted files even if the integrity check fails, instead of failing with an IO error. Warning messages are still printed to syslog if corrupted files are encountered. It can be useful to recover files from disks with bad sectors or other corrupted media. Closes https://github.com/rfjakob/gocryptfs/pull/102 .
2017-03-05Drop Go 1.4 compatability code everywhereJakob Unterwurzacher
Yields a nice reduction in code size.
2017-02-23speed: fix build for Go 1.4 and lowerJakob Unterwurzacher
Old Go versions miss cipher.NewGCMWithNonceSize, which causes: internal/speed/speed.go:95: undefined: cipher.NewGCMWithNonceSize
2017-02-22Implement "gocryptfs -speed"Jakob Unterwurzacher
A crypto benchmark mode like "openssl speed". Example run: $ ./gocryptfs -speed AES-GCM-256-OpenSSL 180.89 MB/s (selected in auto mode) AES-GCM-256-Go 48.19 MB/s AES-SIV-512-Go 37.40 MB/s
