+# Changelog
+
+## 2025-06-19 - 3.2.0 - feat(package)
+Update package.json to use exports field for dual entry points
+
+- Replaced the main and typings fields with an exports object that supports both default and web entry points
+- Ensures consistency in module resolution between Node.js and browser environments
+
+## 2025-06-19 - 3.1.0 - feat(browser)
+Implement fallback SHA256 for non-HTTPS environments and enhance browser tests for consistent hashing
+
+- Added a pure JavaScript SHA256 fallback in ts_web/sha256.fallback.ts for environments without crypto.subtle
+- Updated ts_web/index.ts to use the fallback when necessary
+- Enhanced browser tests in test/test.browser.ts to verify consistent hash outputs
+- Reflected new features in documentation updates (readme.plan.md)
+
+## 2025-06-19 - 3.0.4 - feat  
+Merge isohash functionality into smarthash to enable cross‐environment hash support. This release introduces browser‐compatible SHA256 functions via the Web Crypto API and plugins for environment detection and JSON handling.
+
+- Added new plan and implementation steps to merge isohash into smarthash.
+- Updated test files to use the new tapbundle import.
+- Implemented browser‐specific hashing functions in ts_web/index.ts and ts_web/plugins.ts.
+- Created browser tests in test/test.browser.ts for SHA256 functions.
+- Ensured consistent smarthash functionality across environments.
+
+Note: Several non–breaking maintenance updates (e.g. description, tsconfig, and npmextra.json adjustments) were applied between 2024 and 2023 alongside version marker commits.
+
+---
+
+## 2023-09-22 to 2022-06-26 - 3.0.0 - Maintenance

+- BREAKING CHANGE(core): Switched to ESM, requiring consumers to update their imports accordingly.
+
+---
+
+## 2021-03-01 to 2019-11-21 - 2.1.0 - Maintenance  
+Across versions 2.1.9 down to 2.1.0, the project received multiple fixes and CI updates.
+
+- Repeated “fix(core)” commits improved internal stability.
+- A “fix(ci)” update was also introduced to streamline continuous integration processes.
+
+---
+
+## 2019-11-21 - 2.0.6 - feat  
+New functionality was added to expand the available hashing algorithms.
+
+- feat(md5): Now creates MD5 hashes, broadening the project’s cryptographic capabilities.
+
+---
+
+## 2019-07-04 to 2018-09-07 - 2.0.0 - Maintenance  
+This range of releases was dedicated to refining core functionality and enhancing security.
+
+- Numerous “fix(core)” commits ensured consistent behavior.
+- A “fix(snyk)” commit added a .snyk file and marked the project as Open Source for improved security auditing.
+
+---
+
+## 2018-09-07 - 1.0.4 - BREAKING CHANGE  
+A breaking change was introduced by renaming the package scope.
+
+- BREAKING CHANGE(scope): Changed the package name to @pushrocks/smarthash, requiring updates for consumers referencing the old name.
+
+---
+
+## 2016-08-16 to 2016-05-23 - 1.0.0 - Initial Setup  
+During the early days of the project, core implementation and structure were established.
+
+- Early commits included the initial implementation (“implementation is ready”), package metadata adjustments (e.g. “update package tags”, “fix README”), and structural additions (“add structure”).
+- The journey began with the Initial commit on 2016-05-23, setting the groundwork for future development.

+
+## Usage
+The `@push.rocks/smarthash` library provides a simplified interface to Node.js hash functions, including utilities for hashing strings, files, and streams with popular algorithms like SHA-256 and MD5. Below are detailed examples to demonstrate the capabilities and usage of this library using ESM syntax and TypeScript.
+
+### Hashing Strings
+#### SHA-256
+```typescript
+import { sha256FromString, sha256FromStringSync } from '@push.rocks/smarthash';
+
+// Asynchronously hash a string
+const asyncHash = async () => {
+  const hash = await sha256FromString('Hello, world!');
+  console.log(hash); // Output the hashed string
+};
+asyncHash();
+
+// Synchronously hash a string
+const syncHash = sha256FromStringSync('Hello, world!');
+console.log(syncHash); // Output the hashed string
+```
+
+#### MD5
+```typescript
+import { md5FromString } from '@push.rocks/smarthash';
+
+// Asynchronously hash a string with MD5
+const md5Hash = async () => {
+  const hash = await md5FromString('Hello, world!');
+  console.log(hash); // Output the MD5 hash
+};
+md5Hash();
+```
+
+### Hashing Files
+To hash a file, you can use the `sha256FromFile` function. It reads the file specified by the path and calculates the SHA-256 hash.
+```typescript
+import { sha256FromFile } from '@push.rocks/smarthash';
+
+// Asynchronously hash a file
+const hashFile = async () => {
+  const fileHash = await sha256FromFile('./path/to/your/file.txt');
+  console.log(fileHash); // Output the file's hash
+};
+hashFile();
+```
+
+### Hashing Streams
+`@push.rocks/smarthash` also allows for hashing of streams, which is particularly useful for large files or data streams.
+```typescript
+import { sha256FromStream } from '@push.rocks/smarthash';
+import fs from 'fs';
+
+// Create a read stream from a file
+const readStream = fs.createReadStream('./path/to/your/largeFile.txt');
+
+// Asynchronously hash the stream
+const hashStream = async () => {
+  const streamHash = await sha256FromStream(readStream);
+  console.log(streamHash); // Output the hash of the stream's content
+};
+hashStream();
+```
+
+### Advanced Usage
+#### Hashing Objects
+For hashing JavaScript objects, you can serialize them and hash the resulting string. This is useful for creating hashes from complex data structures.
+```typescript
+import { sha265FromObject } from '@push.rocks/smarthash';
+
+// Hash a JavaScript object
+const hashObject = async () => {
+  const object = { hello: 'world', number: 42 };
+  const objectHash = await sha265FromObject(object);
+  console.log(objectHash); // Output the hash of the object
+};
+hashObject();
+```
+
+#### Error Handling
+All asynchronous functions return promises, so you can use `.catch()` for error handling or try-catch blocks within async functions.
+```typescript
+import { sha256FromString } from '@push.rocks/smarthash';
+
+// Using .catch() for promises
+sha256FromString('test')
+  .then(hash => console.log(hash))
+  .catch(error => console.error(error));
+
+// Using try-catch with async functions
+const getHash = async () => {
+  try {
+    const hash = await sha256FromString('test');
+    console.log(hash);
+  } catch (error) {
+    console.error(error);
+  }
+};
+getHash();
+```
+
+### Best Practices
+- Utilize asynchronous functions for hashing large files or streams to avoid blocking the main thread.
+- For hashing sensitive information, ensure to follow security best practices, including using up-to-date algorithms and managing secrets properly.
+
+By leveraging `@push.rocks/smarthash`, developers can easily integrate hashing functionalities into their Node.js applications, benefiting from its simplified API and TypeScript support for better development experience.

+# Merge Plan: isohash into smarthash
+
+**First line: Command to reread CLAUDE.md**: `cat ~/.claude/CLAUDE.md`
+
+## Objective
+Merge the functionality from @push.rocks/isohash into @push.rocks/smarthash to provide cross-environment hash support (browser and Node.js).
+
+## Implementation Steps
+
+### 1. Create ts_web directory structure ✓
+- Create `./ts_web` directory for browser-specific code
+- This will house the Web Crypto API implementation
+
+### 2. Add required dependencies ✓
+- Add `@push.rocks/smartenv` to package.json dependencies
+- This is needed for environment detection
+
+### 3. Create web-specific plugin file ✓
+- Create `ts_web/plugins.ts` with smartenv import
+- Follow the plugins pattern used in the Node.js version
+
+### 4. Implement browser-compatible hash functions ✓
+- Copy and adapt `index.ts` from isohash to `ts_web/index.ts`
+- Remove circular dependency (isohash importing smarthash)
+- Use native Web Crypto API for SHA256 in browser
+- Maintain compatibility with existing smarthash API
+
+### 5. Build and verify ✓
+- Run `pnpm build` to ensure TypeScript compilation succeeds
+- Check that both Node.js and browser builds are created
+
+### 6. Test functionality ✓
+- Run `pnpm test` to ensure all tests pass
+- Verify browser compatibility through web tests
+
+## Key Considerations
+- The web version uses native Web Crypto API for performance
+- The Node.js version continues using the existing crypto implementation
+- API remains consistent across both environments
+- No breaking changes to existing smarthash functionality
+
+## Additional Features Implemented
+- **Fallback for non-HTTPS environments**: Added pure JavaScript SHA256 implementation that automatically activates when crypto.subtle is not available (e.g., HTTP or file:// protocols)
+- **Comprehensive browser tests**: Created test.browser.ts with specific browser environment tests
+- **Cross-environment consistency**: Ensured hash outputs match across Node.js and browser implementations
