Digest Lens - CRC & Hash Lens – Checksum Viewer
🚀 The fastest way to compute CRC, hashes, and checksums in VS Code — live, inline, zero friction.
DigestLens is a powerful CRC / Hash / Checksum extension for VS Code that automatically calculates and displays digests (CRC32, SHA256, BLAKE3, xxHash…) directly in your workflow.
- ✔ No manual tools
- ✔ No context switching
- ✔ Just instant visibility
DigestLens calcola e visualizza automaticamente i checksum/hash (CRC, Fletcher, SHA, BLAKE3, xxHash) sui tuoi file direttamente nell'Explorer di VS Code.
🔥 Why Developers Love DigestLens
- ⚡ Real-time CRC & hash calculation
- 👁 Inline Explorer badges (see checksums at a glance)
- 🧠 Smart caching = blazing fast
- 🧩 Works with any file via glob rules
- 🛠 Advanced CRC customization (full control)
