+# Session Credentials Encryption Guide
+
+To prevent sensitive OAuth 2 credentials (like access tokens, refresh tokens, and client secrets) from being stored in plaintext inside the session state database, ADK supports encrypting them using Google Cloud KMS with **Envelope Encryption**.
+
+## How It Works
+
+1. **Envelope Encryption for Google OAuth Credentials**:
+   * **Data Encryption Key (DEK)**: A local 256-bit symmetric key (Fernet) is generated locally to encrypt the sensitive fields (`access_token`, `refresh_token`, `client_secret`).
+   * **Key Encryption Key (KEK)**: The Google Cloud KMS key acts as the KEK and is used to encrypt (wrap) the local DEK.
+   * **Storage**: The session stores the locally encrypted credentials, the public reference of the KMS key (`kms_key_name`), and the encrypted DEK (`wrapped_dek`).
+2. **Direct KMS Encryption for Generic Credentials (`SessionStateCredentialService`)**:
+   * All non-OAuth credentials (API keys, HTTP Basic Auth, Bearer tokens, Service Account private keys) saved to session state via `SessionStateCredentialService` are automatically encrypted using Cloud KMS on save (`save_credential`) and decrypted on load (`load_credential`).
+   * Encrypted values are stored in state with a `kms:` prefix.
+3. **In-Memory Caching (Zero Latency)**:
+   * To prevent performing a slow GCP KMS network request on every field encryption or decryption, the resolved plaintext DEK and its corresponding `wrapped_dek` are cached in-memory.
+   * On deserialization, KMS is called **exactly once** per session load, and subsequent decryptions are processed locally in-memory (instantaneous). On serialization, we reuse the cached wrapped DEK (zero KMS calls).
+4. **Re-Authentication Fallback (No-Crash)**:
+   * If Cloud KMS decryption fails (e.g. key destroyed, IAM permission revoked, or key version unavailable), `SessionStateCredentialService` logs a warning and returns `None`, gracefully triggering user re-authentication instead of throwing validation errors.
+5. **Backward Compatibility**: If no KMS key is configured or the stored credentials do not contain encrypted values, ADK automatically falls back to loading/saving them in plaintext without raising errors.
+
+---
+
+## Configuration
+
+Set the environment variable `GOOGLE_CREDENTIAL_KMS_KEY` to point to your GCP KMS CryptoKey (optionally pinning a specific version):
+
+```bash
+export GOOGLE_CREDENTIAL_KMS_KEY="projects/{project_id}/locations/{location}/keyRings/{key_ring_name}/cryptoKeys/{key_name}/cryptoKeyVersions/{version_id}"
+```
+
+Alternatively, you can configure it programmatically on any `CredentialsConfig` (like `BigQueryCredentialsConfig`):
+
+```python
+oauth_credentials_config = BigQueryCredentialsConfig(
+    client_id=client_id,
+    client_secret=client_secret,
+    scopes=scopes,
+    kms_key_name="projects/{project_id}/locations/{location}/keyRings/{key_ring_name}/cryptoKeys/{key_name}/cryptoKeyVersions/{version_id}"
+)
+```
+
+---
+
+## Required IAM Permissions
+
+The Service Account running the ADK Agent / Runner must be granted the appropriate permissions to call the Cloud KMS API.
+
+### KMS Permissions
+* **Role**: `Cloud KMS CryptoKey Encrypter/Decrypter` (`roles/cloudkms.cryptoKeyEncrypterDecrypter`)
+* **Scope**: Must be granted on the specified CryptoKey or KeyRing.
+
+Example `gcloud` command to grant access:
+
+```bash
+gcloud kms keys add-iam-policy-binding {key_name} \
+    --location={location} \
+    --keyring={key_ring_name} \
+    --member="serviceAccount:{agent_service_account}@{project_id}.iam.gserviceaccount.com" \
+    --role="roles/cloudkms.cryptoKeyEncrypterDecrypter"
+```

-"""Checks that a built wheel does not import worse than the last release.
-
-Publishing uploads a wheel without ever installing it. This installs the
-candidate wheel and the previous release side by side, tries to import every
-module each one ships, and compares the two failure sets.
-
-Only the difference matters. A healthy release has a large, stable set of
-modules that fail to import because their optional dependency is absent, so
-the absolute count says nothing. A module that imported in the previous
-release and fails in the candidate is a regression, and so is a brand new
-module that has never imported at all.
-
-Run it locally against any two versions:
-
-  python scripts/verify_release_artifact.py --wheel dist/*.whl
-
-Exit codes: 0 clean, 1 regressions found, 2 the check itself could not run.
-This deliberately depends on nothing outside the standard library, because it
-has to run before the package under test is installed anywhere.
