Rather than adding a new mode to EVP_PKEY_CTX, upstream chose to tie single-shot signing to EVP_MD_CTX, adding functions which combine EVP_Digest*Update and EVP_Digest*Final. This adds a weird vestigial EVP_MD_CTX and makes the signing digest parameter non-uniform, slightly complicating things. But it means APIs like X509_sign_ctx can work without modification. Align with upstream's APIs. This required a bit of fiddling around evp_test.cc. For consistency and to avoid baking details of parameter input order, I made it eagerly read all inputs before calling SetupContext. Otherwise which attributes are present depend a lot on the shape of the API we use---notably the NO_DEFAULT_DIGEST tests for RSA switch to failing before consuming an input, which is odd. (This only matters because we have some tests which expect the operation to abort the operation early with parameter errors and match against Error. Those probably should not use FileTest to begin with, but I'll tease that apart a later time.) Upstream also named NID_Ed25519 as NID_ED25519, even though the algorithm is normally stylized as "Ed25519". Switch it to match.

BoringSSL SSL Tests
This directory contains BoringSSL's protocol-level test suite.
Testing a TLS implementation can be difficult. We need to produce invalid but sufficiently correct handshakes to get our implementation close to its edge cases. TLS's cryptographic steps mean we cannot use a transcript and effectively need a TLS implementation on the other end. But we do not wish to litter BoringSSL with options for bugs to test against.
Instead, we use a fork of the Go crypto/tls
package, heavily patched with
configurable bugs. This code, along with a test suite and harness written in Go,
lives in the runner
directory. The harness runs BoringSSL via a C/C++ shim
binary which lives in this directory. All communication with the shim binary
occurs with command-line flags, sockets, and standard I/O.
This strategy also ensures we always test against a second implementation. All features should be implemented twice, once in C for BoringSSL and once in Go for testing. If possible, the Go code should be suitable for potentially upstreaming. However, sometimes test code has different needs. For example, our test DTLS code enforces strict ordering on sequence numbers and has controlled packet drop simulation.
To run the tests manually, run go test
from the runner
directory. It takes
command-line flags found at the top of runner/runner.go
. The -help
option
also works after using go test -c
to make a runner.test
binary first.
If adding a new test, these files may be a good starting point:
runner/runner.go
: the test harness and all the individual tests.runner/common.go
: contains theConfig
andProtocolBugs
struct which control the Go TLS implementation's behavior.test_config.h
,test_config.cc
: the command-line flags which control the shim's behavior.bssl_shim.cc
: the shim binary itself.
For porting the test suite to a different implementation see PORTING.md.
