Android Apps on Windows 11: Safe Alternatives After WSA

In 2025, Microsoft announced it would discontinue support for the Windows Subsystem for Android (WSA), making Android applications non-functional on Windows 11. This decision surprised many users in Indonesia who relied on these applications. HP developed a guide outlining secure alternatives to WSA, which included reputable Android emulators like BlueStacks, LDPlayer, and NoxPlayer, as well as native Windows alternatives such as Microsoft Teams and Microsoft 365 apps. Users were advised against unverified APK sideloading, unofficial emulators, and modified apps due to security risks. Microsoft’s end of support means no further security updates or bug fixes will be provided, and integration with the Amazon Appstore will cease. Users can continue using WSA apps, but they will be exposed to potential security threats. To migrate data from WSA, users were instructed to inventory apps, research alternatives, and export app data before performing a clean uninstall. Best practices for running Android apps safely on Windows included downloading from official sources and keeping software updated.

Local Data Security with Android Keystore

Threema, a secure messaging application, prioritizes user privacy by avoiding server-side storage and ensuring that message content remains on users' devices. On Android, it utilizes the Keystore for secure cryptographic key management, storing data in an app-specific directory to isolate it from other applications. All stored data is encrypted, making it unreadable without the appropriate key. The Android Keystore allows for key generation without direct access to raw data, enhancing security by performing cryptographic operations internally. Modern devices with dedicated security chips provide hardware-backed security, while older devices rely on a software-backed Keystore, which is more vulnerable. Threema offers users the option to set a passphrase, adding an extra layer of protection by encrypting data before it is stored in the Keystore. This multi-layered security strategy adapts to the device's capabilities.

Take Control: Customer-Managed Keys for Lakebase Postgres

Encryption at rest is essential for cloud environments, especially in regulated sectors. Lakebase offers Customer Managed Keys (CMK), allowing organizations to control their encryption keys from preferred Key Management Services (KMS) like AWS KMS, Azure Key Vault, or Google Cloud KMS. Lakebase CMK manages both persistent storage and ephemeral compute, ensuring data security. Lakebase's architecture separates storage and compute layers, enabling elastic scaling and serverless operations. The storage layer maintains persistent data, while the compute layer consists of dynamic Postgres instances. This separation poses encryption challenges, addressed by Lakebase CMK through a hierarchical Envelope Encryption model. The key hierarchy includes: 1. Customer Managed Key (CMK): The Root of Trust in the cloud KMS, never accessed in plaintext by Databricks. 2. Key Encryption Key (KEK): A transient key for wrapping data keys. 3. Data Encryption Keys (DEKs): Unique keys for each data segment, stored in an encrypted state. When data access is needed, Lakebase retrieves DEKs by unwrapping keys from the KMS. If a key is revoked, access to the data is denied, and ephemeral compute instances are terminated. In practice, CMK applies to: 1. Persistence Layer (Storage): All data segments are encrypted with keys controlled by the CMK. 2. Ephemeral Layer (Compute): Each compute instance generates a unique ephemeral key, and upon revocation, the instance is terminated, destroying in-memory keys. CMK implementation follows a delegation model, allowing Security Admins to manage keys without accessing data. The process includes key configuration, workspace binding, and lifecycle management. Key rotation is seamless, requiring no data re-encryption. All cryptographic operations involving the CMK are logged by the cloud provider's audit service. Lakebase CMK is available for Enterprise tier customers, allowing organizations to manage their encryption keys effectively.

The antivirus feature I skip on every SSD-powered PC

File shredders may not effectively erase data on solid-state drives (SSDs) due to the way SSDs distribute data, which can lead to deleted files remaining retrievable. Additionally, using file shredders can reduce the lifespan of SSDs because of their limited write cycles. Instead of file shredders, drive encryption is recommended for protecting sensitive data on SSDs, as it ensures that deleted data remains unreadable. Windows 11 offers integrated drive encryption for users with a Microsoft account, and tools like VeraCrypt or Cryptomator can create encrypted folders for managing sensitive documents. It's important to safeguard access to encrypted data by backing up decryption passwords or recovery keys.

Databricks Postgres Gets Customer Key Control

Databricks has introduced customer-managed keys (CMK) for its Lakehouse Postgres offering, allowing users to control their data encryption and utilize their own Key Management Service (KMS) from major cloud providers like AWS KMS, Azure Key Vault, or Google Cloud KMS. The Lakehouse Postgres architecture features a hierarchical envelope encryption model with three tiers: the customer-managed root key (CMK), a Key Encryption Key (KEK) used by Databricks' Key Manager Service, and unique Data Encryption Keys (DEKs) for each data segment. If a CMK is revoked, access to the data is denied, and active compute instances are terminated, serving as a failsafe for high-compliance workloads. The implementation allows for granular control over key management and supports seamless key rotation without data re-encryption or downtime. All cryptographic operations are logged within the customer's cloud audit services, available to Databricks Enterprise tier customers.
