The Hash Generator tool lets you create cryptographic hashes from any text input using algorithms such as SHA-1 and SHA-256. A hash function converts data into a fixed-length string that is designed to be unique for each distinct input. Hashing is a one-way process, which means the original text cannot be recovered from the hash. This property makes hashes useful for verifying integrity and storing passwords safely when implemented correctly.

You can use this tool to explore how hashing works, generate checksums for small pieces of data, or test how different algorithms produce different outputs. For example, developers often use hashes to confirm that a file has not been modified, while security systems use salted hashes to compare passwords without ever storing them in plain text. The tool accepts any text and returns the hash in hexadecimal form.

All calculations happen directly in your browser using the Web Crypto API, so your input is never transmitted or logged. While this tool is suitable for educational and light professional use, it should not be considered a full replacement for production-grade security libraries. It is, however, an excellent way to understand and experiment with hashing in a safe, convenient environment.
