##### Browser crypto footprint



The browser bundle keeps the public key, signature, transaction digest, and memo-encryption behavior compatible with Node. Hashing is provided by `@noble/hashes`, and memo AES-256-CBC encryption/decryption is provided by `aes-js`, so the bundle does not need the generic Browserify `crypto` shim path (`crypto-browserify`, `browserify-sign`, or `create-ecdh`) for these helpers. The `secp256k1` dependency is still required for key and signature operations; in browser builds it uses its own JavaScript fallback.

The browser bundle keeps the public key, signature, transaction digest, and memo-encryption behavior compatible with Node. Hashing is provided by `@noble/hashes`, secp256k1 key/signature/ECDH operations are provided by `@noble/secp256k1`, and memo AES-256-CBC encryption/decryption is provided by `aes-js`. The bundle does not include the generic Browserify `crypto` shim path (`crypto-browserify`, `browserify-sign`, or `create-ecdh`) and does not include the historical `secp256k1`/`elliptic` dependency path.



##### Runtime compatibility matrix



| Runtime | Support level | Required platform features | Notes |

| --- | --- | --- | --- |

| Node.js 18+ | Supported | CommonJS, `Buffer`, typed arrays, `TextEncoder`/`TextDecoder`, built-in `crypto` for Node consumers/tests | Primary server-side runtime for dblurt. |

| Modern desktop/mobile browsers | Supported through `dist/dblurt.js` | ES2015, typed arrays, `DataView`, `TextEncoder`/`TextDecoder`, `Math.imul` | Covers key generation, key validation, signatures, public-key recovery, transaction signing, transaction digesting, and encrypted memos without Browserify crypto signing/ECDH shims. |

| WebViews based on modern Chromium/WebKit | Supported when the WebView exposes the browser features above | Same as modern browsers | Hosts may need to provide `TextEncoder`/`TextDecoder` on older embedded WebViews. |

| Legacy browsers without ES2015 typed-array support | Unsupported | Missing required primitives | Use a modern browser/WebView or add host-level polyfills before loading dblurt. |



### Tools Class

Some useful functions like mana with regeneration calculation, vote value calculation, etc...
