crypto/sha256 — validation proof
Go’s own crypto/sha256 test suite, converted to C# by go2cs, built against the converted standard
library, run under the Go-semantics test host, and compared verdict for verdict against a clean
go test -json baseline of the same sources. This page is generated by the converter from that
comparison — it is the evidence behind the crypto/sha256 row in
Validated Test Packages.

Disclosed divergences
A disclosed divergence is a specific Go assertion the managed CLR provably cannot satisfy — not
a skipped test and not a tolerance. Each one is pinned by exact failure signature in the package’s
hand-owned go2cs_test_disclosures.json;
a disclosed test that fails any other way is still a hard mismatch.
| Test | Class | Pinned reason |
|---|---|---|
TestAllocations |
alloc-profile |
want-zero AllocsPerRun assert: Sum copies the digest (d0 := *d) so the caller can keep writing, and that copy must deep-copy the digest’s [8]uint32 state and [64]byte block — golib’s array |
Excluded declarations
Declarations filtered from both sides of the comparison, and therefore not claimed above:
Benchmark, Fuzz and Example declarations the converted host does not execute, plus any
test requiring a capability the managed runtime does not provide — a testing member the host
has not implemented, or a platform behavior it provably cannot reproduce. Each is named with
the capability it needs.
