2016-10-04without_openssl: support compiling completely without opensslJakob Unterwurzacher
Build helper script: build-without-openssl.bash
2016-09-26reverse: switch from GCM-SIV to AES-SIVv1.1-beta1Jakob Unterwurzacher
GCM-SIV is not yet finalized, and the reference implemenation is painfully slow at about 2 MB/s. Switch to AES-SIV.
2016-09-25stupidgcm: add GCM-SIV benchmarkJakob Unterwurzacher
On a CPU without AES-NI: $ go test -bench . Benchmark4kEncStupidGCM-2 50000 24155 ns/op 169.57 MB/s Benchmark4kEncGoGCM-2 20000 93965 ns/op 43.59 MB/s Benchmark4kEncGCMSIV-2 500 2576193 ns/op 1.59 MB/s
2016-09-25Implement changes proposed by gosimple.Jakob Unterwurzacher
Also delete the unused "dirIVNameStruct", found by deadcode.
2016-07-04stupidgcm: use __builtin_trap()Jakob Unterwurzacher
[...]/stupidgcm/locking.go:16:2: warning: indirection of non-volatile null pointer will be deleted, not trap [-Wnull-dereference] [...]/stupidgcm/locking.go:16:2: note: consider using __builtin_trap() or qualifying pointer with 'volatile' https://github.com/rfjakob/gocryptfs/issues/15
2016-05-22stupidgcm: add benchmark.bash wrapperJakob Unterwurzacher
Add a simple bash wrapper to make it easier to run the GCM benchmarks.
2016-05-05stupidgcm: set dummy locking callback.v0.10-rc2Jakob Unterwurzacher
In general, OpenSSL is only threadsafe if you provide a locking function through CRYPTO_set_locking_callback. However, the GCM operations that stupidgcm uses never call that function. To guard against that ever changing, set a dummy locking callback that crashes the app.
2016-05-05stupidgcm: skip tests on Go 1.4 and olderJakob Unterwurzacher
Quoting from the patch: We compare against Go's built-in GCM implementation. Since stupidgcm only supports 128-bit IVs and Go only supports that from 1.5 onward, we cannot run these tests on older Go versions.
2016-05-05Revert "stupidgcm: print openssl error stack before panicing"Jakob Unterwurzacher
This did not help in debugging the openssl <= 1.0.1c issue at all and makes the code more complex. Keep it simple.
2016-05-05stupidgcm: reorder calls to support openssl <= 1.0.1cJakob Unterwurzacher
This fixes the test failures on Travis CI. Quoting from https://github.com/openssl/openssl/commit/07a4ff79d23e45f1a45da717b7c1f41a5e1c7c0c /* Set expected tag value. A restriction in OpenSSL 1.0.1c and earlier * required the tag before any AAD or ciphertext */
2016-05-04stupidgcm: print openssl error stack before panicingJakob Unterwurzacher
2016-05-04stupidgcm: fix copy-paste error in panic messageJakob Unterwurzacher
Also, print the openssl version in Travis CI
2016-05-04stupidgcm: add our own thin wrapper around openssl gcmJakob Unterwurzacher
...complete with tests and benchmark. This will allow us to get rid of the dependency to spacemonkeygo/openssl that causes problems on Arch Linux ( https://github.com/rfjakob/gocryptfs/issues/21 )
