## Overview

The Hash Generator is a secure utility tool designed to compute cryptographic hash values for any input text, supporting industry-standard algorithms including MD5, SHA1, SHA256, and SHA512.

## Inputs

- **Hash Algorithm** (select)
- **Input Text** (textarea): Enter text to hash...
- **Input Format** (select)
- **Output Format** (select)

## When to use

- Verifying the integrity of data or files to ensure they have not been tampered with.
- Generating unique identifiers or fingerprints for sensitive strings and passwords.
- Comparing two pieces of data to check for equality without exposing the original content.

## How it works

- Enter your source data into the input field and select your preferred input format (Plain Text, Hex, or Base64).
- Choose the desired cryptographic algorithm from the dropdown menu, such as SHA256 for secure applications.
- Select your preferred output encoding format, typically Hexadecimal, to view the generated hash string.
- Click generate to instantly compute and display the resulting hash value.

## Use cases

- Validating file downloads by comparing generated checksums against provided hashes.
- Creating unique keys for caching mechanisms in web development.
- Anonymizing sensitive user data for database storage or logging.

## Frequently asked questions

### What algorithms are supported?

The tool supports MD5, SHA1, SHA256, and SHA512.

### Is my data stored on your servers?

No, all hashing operations are performed locally in your browser for your privacy and security.

### What is the difference between Hex and Base64 output?

Hexadecimal uses a base-16 system (0-9, a-f), while Base64 uses a base-64 system, resulting in a more compact string representation.

### Can I use this for password hashing?

While you can generate hashes, it is recommended to use specialized, salted password hashing functions like Argon2 or bcrypt for production security.

### Why does the same input produce different hashes?

Ensure you are using the same algorithm and input format; even a single hidden space or newline character will result in a completely different hash.

Three modes: (1) generate a fresh verifier + challenge from cryptographically secure random bytes at 256/384/512/768-bit entropy, (2) audit a verifier you already have against the RFC — length (43–128), charset \[A-Za-z0-9-._~\] and ≥256-bit entropy, and (3) verify a verifier/challenge pair by recomputing BASE64URL(SHA256(verifier)). Optionally build the full authorization-request URL and token-exchange body. Complements the generic nonce-generator (which only emits a verifier+challenge pair) with RFC-compliance auditing and pair verification.
