2021-08-24benchmark.bash: add -xchacha supportJakob Unterwurzacher
2021-08-23xray: add xchacha supportJakob Unterwurzacher
Also use the new cryptocore algo names.
2021-08-23contentenc: remove unused NonceMode constantsJakob Unterwurzacher
Looks like these are part of an abandoned plan.
2021-08-23speed: use algo names from cryptocoreJakob Unterwurzacher
2021-08-23cryptocore: add NonceSize to AEADTypeEnumJakob Unterwurzacher
Have the information in one centralized place, and access it from main as needed.
2021-08-23tests/cli: add -xchacha testsJakob Unterwurzacher
2021-08-23tests/matrix: add -xchacha testJakob Unterwurzacher
2021-08-23configfile: add Validate() function, support FlagXChaCha20Poly1305Jakob Unterwurzacher
We used to do validation using lists of mandatory feature flags. With the introduction of XChaCha20Poly1305, this became too simplistic, as it uses a different IV length, hence disabling GCMIV128. Add a dedicated function, Validate(), with open-coded validation logic. The validation and creation logic also gets XChaCha20Poly1305 support, and gocryptfs -init -xchacha now writes the flag into gocryptfs.conf.
2021-08-23Add partial XChaCha20-Poly1305 support (mount flag only)Jakob Unterwurzacher
Mount flag only at the moment, not saved to gocryptfs.conf. https://github.com/rfjakob/gocryptfs/issues/452
2021-08-23test/cli: actually run TestZerokeyJakob Unterwurzacher
As the filename did not end in _test.go, TestZerokey was not actually run. Fix that. renamed: tests/cli/zerokey.go -> tests/cli/zerokey_test.go
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/%
2021-08-23ensurefds012: package comment should preceded package statementJakob Unterwurzacher
This makes the comment visible to godoc.
2021-08-21configfile: pass struct to Create 2/2Jakob Unterwurzacher
Drop Create and rename Create2 to Create.
2021-08-21configfile: pass struct to Create 1/2Jakob Unterwurzacher
The argument list got too long. Part 1: Replace with Create2
2021-08-21cryptocore: drop IVLen helper varJakob Unterwurzacher
The IVLen var seems be a net loss in clarity. Drop it. Also add comments and normalize error messages.
2021-08-20README: Update changelog with -deterministic-namesJakob Unterwurzacher

2021-08-20-deterministic-names: implement for reverse mode, tooJakob Unterwurzacher
2021-08-20MANPAGE: move nosyslog to MOUNT OPTIONS sectionJakob Unterwurzacher
It was in INIT OPTIONS by mistake.
2021-08-20-deterministic-names: accept flag on -initJakob Unterwurzacher
And store it in gocryptfs.conf (=remove DirIV feature flag).
2021-08-20Implement -deterministic-names: extended -zerodirivJakob Unterwurzacher
-deterministc-names uses all-zero dirivs but does not write them to disk anymore.

Typo inside doInit.

This makes fsck runs deterministic again.
