As v0.4 introduced ext4-style feature flags, the on-disk format version
is unlinkely to change. Drop it from the version output to reduce
clutter. Use "gocryptfs -version -debug" to see it.
Add the Go version string because only Go 1.6 and newer have an optimized
AES-GCM implementation. This will help users to understand the performance
of their build.
Go GCM is faster than OpenSSL if the CPU has AES instructions
and you are running Go 1.6+.
The "-openssl" option now defaults to "auto".
"gocryptfs -debug -version" displays the result of the autodetection.
See https://github.com/rfjakob/gocryptfs/issues/23 for details and
benchmarks.
