The rewritten openssl backend does not support this flag anymore,
and it was inherently dangerour. Drop it (ignored for compatibility)
|

New() -> NewAES256GCM()
Also add missing NewChacha20poly1305
constructor in without_openssl.go.

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/%
|
|
Yields a nice reduction in code size.

|
Old Go versions miss cipher.NewGCMWithNonceSize, which causes:
internal/speed/speed.go:95: undefined: cipher.NewGCMWithNonceSize
|
|
A crypto benchmark mode like "openssl speed".
Example run:
$ ./gocryptfs -speed

AES-GCM-256-Go 48.19 MB/s
AES-SIV-512-Go 37.40 MB/s
