## About

Hashes are one-way fingerprints of data. Compare two hashes to verify that a file was not tampered with, store passwords securely, or check an integrity checksum after a download.

This tool computes MD5, SHA-1, SHA-256, and SHA-512 digests of any text you type — or any file you drop in. Every hash updates live as you type.

## How to use

1. **Type or paste text** — All four digests update live as you type.
2. **Hash a file instead** — Drop a file anywhere on the page to compute its checksum — useful for verifying downloads.
3. **Copy any digest** — Each hash has its own copy button.

## Examples

### The classic "abc" vector

Well-known reference digests.

Input:

```
abc
```

Output:

```
MD5 900150983cd24fb0d6963f7d28e17f72 · SHA-256 ba7816bf8f01cfea414140de5dae2223b00361a396177a9cb410ff61f20015ad
```

## FAQ

### What is the difference between the algorithms?

MD5 and SHA-1 are fast but considered weak for security purposes. SHA-256 and SHA-512 are modern, cryptographically secure choices recommended for new work.

### Can I reverse a hash?

No. Hashing is one-way by design. The only way to "reverse" it is to guess the input and compare hashes, which is why strong passwords matter.

### Why do hashes look random?

Even a tiny change in input produces a completely different digest. That avalanche effect is what makes hashes useful for detecting tampering.
