Add optional support for AEGIS encryption

2025-03-12T19:43:23+00:00

AEGIS is a new family of authenticated encryption algorithms that offers stronger security, higher usage limits, and better performance than AES-GCM. This pull request adds support for a new `-aegis` command-line flag, allowing AEGIS-128X2 to be used as an alternative to AES-GCM on CPUs with AES acceleration. It also introduces the ability to use ciphers with different key sizes. More information on AEGIS is available here: - https://cfrg.github.io/draft-irtf-cfrg-aegis-aead/draft-irtf-cfrg-aegis-aead.html - https://github.com/cfrg/draft-irtf-cfrg-aegis-aead gocryptfs -speed speed on Apple M1: AES-GCM-256-OpenSSL 3718.79 MB/s AES-GCM-256-Go 5083.43 MB/s (selected in auto mode) AES-SIV-512-Go 625.20 MB/s XChaCha20-Poly1305-OpenSSL 1358.63 MB/s (selected in auto mode) XChaCha20-Poly1305-Go 832.11 MB/s Aegis128X2-Go 11818.73 MB/s gocryptfs -speed speed on AMD Zen 4: AES-GCM-256-OpenSSL 5215.86 MB/s AES-GCM-256-Go 6918.01 MB/s (selected in auto mode) AES-SIV-512-Go 449.61 MB/s XChaCha20-Poly1305-OpenSSL 2643.48 MB/s XChaCha20-Poly1305-Go 3727.46 MB/s (selected in auto mode) Aegis128X2-Go 28109.92 MB/s

stupidgcm: detect AES-GCM acceleration like crypto/tls

2024-06-06T08:07:08+00:00

Instead of just looking for AES, also look for PCLMULQDQ, like crypto/tls does. Fixes: https://github.com/rfjakob/gocryptfs/issues/822

gocryptfs -speed: call testing.Init() to not panic

2023-09-15T21:19:02+00:00

Looks like I should have been calling testing.Init() all along. From https://pkg.go.dev/testing#Init : > Init is only needed when calling functions such as > Benchmark without using "go test". Panic only affected without_openssl builds and looks like this: $ ./gocryptfs -speed gocryptfs v2.4.0-2-g8b1c4b0-dirty without_openssl; go-fuse v2.3.0; 2023-09-15 go1.21.1 linux/amd64 cpu: Intel(R) Core(TM) i5-6500 CPU @ 3.20GHz; with AES acceleration AES-GCM-256-OpenSSL panic: runtime error: invalid memory address or nil pointer dereference [signal SIGSEGV: segmentation violation code=0x1 addr=0x0 pc=0x5a5d20] goroutine 7 [running]: testing.(*common).decorate(0x40d625?, {0xc00001c150, 0x2a}, 0x830601?) testing/testing.go:772 +0xa0 [...] Fixes: https://github.com/rfjakob/gocryptfs/issues/789 Relates-to: https://github.com/golang/go/issues/62666
