Multi Hasher New

The Multi Hasher allows you to compute several cryptographic hashes in one step: MD5, SHA-1, SHA-256, and SHA-512. This side-by-side comparison is invaluable for understanding differences in digest length, collision resistance, and algorithm performance. It simplifies tasks such as migrating systems from legacy MD5 or SHA-1 to more secure SHA-2 families by providing immediate visual confirmation of hash changes.

- **MD5**: 128-bit, very fast, broken for security. - **SHA-1**: 160-bit, deprecated due to collision attacks. - **SHA-256**: 256-bit, current industry standard. - **SHA-512**: 512-bit, highest collision resistance on 64-bit platforms.

All four hash functions are initialized with their standard constants and fed the same input byte stream. Each algorithm’s compression function runs in parallel (or sequentially) over the input blocks. Finally, each result is formatted as a hexadecimal string and returned in a JSON object keyed by algorithm name.

— **Migration Validation**: Confirm that switching from MD5/SHA-1 to SHA-256 does not alter file workflows. — **Audit & Compliance**: Demonstrate compliance by showing modern hash adoption alongside legacy values. — **Education**: Teach students about hash algorithm differences in a live, interactive manner.

Computing multiple hashes increases CPU usage linearly. Use hardware acceleration (AES-NI, SHA extensions) or multithreading (Web Workers) to maintain responsiveness in client applications.

This tool is for analysis only. For production security, choose a single strong hash (SHA-256 or SHA-512) with proper salting or HMAC. Do not rely on MD5 or SHA-1 for any security-critical context.
