The Terminator_Error exception is declared but never documented. Add a comment explaining when this exception is raised and how it should be handled.

The comment says 'RSA' but should say 'RNG' since this is the Is_Valid function for RNG_Key_Type.

The constant name nul could be more descriptive. Consider renaming to Null_Terminator or Nul_Byte to better indicate its purpose as a null terminator character.

One minor comment about using XMALLOC over malloc. In the future we may need something like the static memory feature so starting out with XMALLOC would help for if using a heap hint later.

Thank you for adding in the test cases. I compiled both the examples and tests and they ran okay with a newer version of gnat, not sure about old versions of gnat.

wrapper/Ada/wolfssl.adb is the body of package WolfSSL, but it has a with WolfSSL; clause. A unit cannot with itself; this will cause a circular dependency / compilation error. Remove the self-with and instead with the actual dependencies needed by the body (or rely on the spec’s withs where appropriate).

+         AUnit.Assertions.Assert
+           (Hash_Bytes = Expected_Hash,
+            "SHA256('asdf') hash mismatch");


Expected_Hash returned by Hex_Bytes is indexed 0 .. 31, but Hash_Bytes is indexed 1 .. 32. For Interfaces.C.char_array, predefined equality includes bounds, so this comparison will fail even when the bytes match. Normalize bounds (e.g., make both arrays use the same range) before comparing.

wrapper/Ada/tests/src/aes_bindings_tests.adb

+      AUnit.Assertions.Assert
+        (Decoded = Plain,
+         "AES-CBC roundtrip mismatch");


Plain comes from Test_Support.Bytes (0-based Byte_Array), but Decoded is declared Byte_Array (1 .. Plain'Length), so Decoded = Plain will fail due to different bounds even if the data matches. Declare Cipher/Decoded with Plain'Range (or otherwise normalize ranges) so equality is meaningful.

+      Last_N : constant Natural := (if S'Length = 0 then 0 else S'Length - 1);
+      B      : WolfSSL.Byte_Array (0 .. WolfSSL.Byte_Index (Last_N));
+      N      : Natural := 0;


For empty input, Last_N is set to 0 and B becomes Byte_Array (0 .. 0), which is a 1-byte array rather than an empty buffer. If callers intend Bytes("") to represent an empty C buffer, consider returning a null range (e.g. 1 .. 0) for the empty-string case.

Copilot · 2026-02-06T18:10:56Z

wrapper/Ada/tests/src/support/test_support.adb

+      declare
+         N      : constant Natural := Len / 2;
+         Last_N : constant Natural := (if N = 0 then 0 else N - 1);
+         B      : WolfSSL.Byte_Array (0 .. WolfSSL.Byte_Index (Last_N));
+         Hi     : Natural;


When Hex is empty, this constructs Byte_Array (0 .. 0) (1 byte) instead of an empty buffer. Consider returning a null range for N = 0 so Hex_Bytes("") is truly empty, and to avoid bound-mismatch surprises in callers.

@julek-wolfssl please squash the 51 commits. Also review the latest copilot findings. Thanks

Add Ada bindings for SHA-256, RSA sign/verify, and AES-CBC from wolfCrypt. Use XMALLOC/XFREE for dynamic allocation and add GNATprove ownership annotations to enable static leak detection. Refactor the Ada wrapper into a base package (wolfssl.ads) and a child package (wolfssl-full_runtime) to separate code that depends on Interfaces.C.Strings and GNAT.Sockets from zero-footprint-compatible code. Add standalone examples for SHA-256 hashing, RSA signature verification, and AES encryption under wrapper/Ada/examples/. Add AUnit test suites for SHA-256, RSA, and AES bindings under wrapper/Ada/tests/ with Valgrind suppressions and Alire integration. Move TLS client/server examples into wrapper/Ada/examples/src/ and update build files (default.gpr, examples.gpr, include.am) accordingly. Update CI (ada.yml) to build default.gpr, run AUnit tests, run the client-server examples, and run GNATprove. Co-authored-by: Joakim Strandberg <joakim@mequinox.se>
