Run "make format" using go version go1.19.4 linux/amd64

go.mod: fix jacobsa/crypto build on riscv64

2022-12-21T17:38:11+00:00

Replace dependency jacobsa/crypto with a fork with support for riscv64. Issue: https://github.com/rfjakob/gocryptfs/issues/666 Upstream PR: https://github.com/jacobsa/crypto/issues/13 Unaddressed on jacobsa/crypto: https://github.com/jacobsa/crypto/pull/14#issuecomment-1182744229 Signed-off-by: Christian Stewart

cryptocore: disentangle algorithm / library implementation name

2021-09-28T16:09:31+00:00

Used in gocryptfs-xray, and will also be used in -info.

-speed: print cpu model

2021-09-14T16:58:22+00:00

When somebody posts "gocryptfs -speed" results, they are most helpful together with the CPU model. Add the cpu model to the output. Example: $ ./gocryptfs -speed gocryptfs v2.2.0-beta1-5-g52b0444-dirty; go-fuse v2.1.1-0.20210825171523-3ab5d95a30ae; 2021-09-14 go1.17.1 linux/amd64 cpu: Intel(R) Core(TM) i5-3470 CPU @ 3.20GHz; with AES acceleration AES-GCM-256-OpenSSL 862.79 MB/s AES-GCM-256-Go 997.71 MB/s (selected in auto mode) AES-SIV-512-Go 159.58 MB/s XChaCha20-Poly1305-OpenSSL 729.65 MB/s XChaCha20-Poly1305-Go 843.97 MB/s (selected in auto mode)

-speed: drop useless tab at end of line

2021-09-14T08:15:18+00:00

cli: drop -forcedecode flag

2021-09-10T10:14:19+00:00

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

-speed: show which xchacha implementation is preferred

2021-09-08T18:46:52+00:00

stupidgcm: add PreferOpenSSL{AES256GCM,Xchacha20poly1305}

2021-09-08T17:48:13+00:00

Add PreferOpenSSLXchacha20poly1305, rename PreferOpenSSL -> PreferOpenSSLAES256GCM.
