Pull request overview

This pull request adds image generation verification capabilities to the NEAR AI Cloud verifier tool, implementing both standard signature verification and end-to-end encrypted image generation. The changes introduce new TypeScript and Python implementations that follow the existing patterns established by the chat verifier.

Changes:

Added image generation verifier for both TypeScript and Python with signature and attestation verification
Added encrypted image generation verifier supporting both ECDSA and Ed25519 encryption algorithms
Refactored encryption utilities into shared modules (encryption_utils.ts and encryption_utils.py) to reduce code duplication
Updated encrypted_chat_verifier to use the shared encryption utilities
Added npm scripts for running image and encrypted-image verifiers
Extended README with comprehensive documentation for image generation verification

py/encrypted_image_verifier.py

+    except requests.exceptions.HTTPError as e:
+        print(f"✗ Request failed: {e}")
+        if e.response is not None:
+            print(f"  Status code: {e.response.status_code}")
+            try:
+                error_detail = e.response.json()
+                print(f"  Error detail: {json.dumps(error_detail, indent=2)}")
+            except Exception as e:
+                print(f"✗ Failed to parse error detail: {e}")
+                print(f"  Response text: {e.response.text[:200]}")


Variable shadowing: the exception variable 'e' on line 113 shadows the outer 'e' from line 106. On line 115, when accessing e.response.text, this refers to the inner exception from the JSON parsing, not the HTTPError. Consider renaming the inner exception variable to avoid confusion, e.g., except Exception as parse_error:

Suggested change

except requests.exceptions.HTTPError as e:

print(f"✗ Request failed: {e}")

if e.response is not None:

print(f" Status code: {e.response.status_code}")

try:

error_detail = e.response.json()

print(f" Error detail: {json.dumps(error_detail, indent=2)}")

except Exception as e:

print(f"✗ Failed to parse error detail: {e}")

print(f" Response text: {e.response.text[:200]}")

except requests.exceptions.HTTPError as http_error:

print(f"✗ Request failed: {http_error}")

if http_error.response is not None:

print(f" Status code: {http_error.response.status_code}")

try:

error_detail = http_error.response.json()

print(f" Error detail: {json.dumps(error_detail, indent=2)}")

except Exception as parse_error:

print(f"✗ Failed to parse error detail: {parse_error}")

print(f" Response text: {http_error.response.text[:200]}")

py/image_verifier.py

+async def main():
+    """Run example verification of image generation."""
+    parser = argparse.ArgumentParser(description="Verify NEAR AI Cloud Signed Image Generation Responses")
+    parser.add_argument("--model", default="Qwen/Qwen-Image")


The default model in Python implementation is "Qwen/Qwen-Image", but the TypeScript implementation uses "black-forest-labs/FLUX.2-klein-4B". All documentation in README.md refers to the FLUX model. Consider aligning the Python default with the TypeScript implementation for consistency.

Suggested change

parser.add_argument("--model", default="Qwen/Qwen-Image")

parser.add_argument("--model", default="black-forest-labs/FLUX.2-klein-4B")

py/encrypted_image_verifier.py

+    parser = argparse.ArgumentParser(
+        description="Test End-to-End Encryption for NEAR AI Cloud Image Generation"
+    )
+    parser.add_argument("--model", default="Qwen/Qwen-Image")


The default model is "Qwen/Qwen-Image", but it should be "black-forest-labs/FLUX.2-klein-4B" to match the TypeScript implementation at ts/encrypted_image_verifier.ts:222 and all documentation in README.md.

Suggested change

parser.add_argument("--model", default="Qwen/Qwen-Image")

parser.add_argument("--model", default="black-forest-labs/FLUX.2-klein-4B")

ts/encryption_utils.ts

+ * (Used by non-streaming examples and attestation key fetch.)
+ */
+export async function makeRequest(url: string, options: any = {}): Promise<any> {
+  return await new Promise((resolve, reject) => {


The await keyword is unnecessary here since new Promise already returns a Promise. Remove the await to simplify the code: return new Promise((resolve, reject) => {

Suggested change

return await new Promise((resolve, reject) => {

return new Promise((resolve, reject) => {

ts/encryption_utils.ts

+    const req = client.request(requestOptions, (res) => {
+      let data = '';
+      res.on('data', (chunk) => {
+        data += chunk.toString();


The explicit .toString() call is inconsistent with the existing pattern in the codebase. Both chat_verifier.ts:66 and image_verifier.ts:73 use data += chunk; without calling .toString(). Consider removing .toString() for consistency: data += chunk;

Suggested change

data += chunk.toString();

data += chunk;

ts/encrypted_image_verifier.ts

+  }
+
+  const payload: ImageGenerationResponse = response;
+  const imageId = payload.id || 'unknown';


If payload.id is missing, the code sets imageId to 'unknown' and continues, but this will cause verifyImage to fail when it tries to fetch the signature. Consider checking for a valid id and returning early, similar to the pattern in image_verifier.ts lines 246-250.

Suggested change

const imageId = payload.id || 'unknown';

if (!payload.id) {

console.log('✗ Response is missing image ID; cannot verify image.');

return;

}

const imageId = payload.id;
