# SHA-1 Hash Generator for Text and Files

Generate 160-bit SHA-1 checksums for strings and binary files directly inside your browser via Web Crypto.

## What is SHA-1 Hash Generator for Text and Files?

The SHA-1 Hash Generator computes the 160-bit SHA-1 digest of text or of any file you choose, shown as a 40-character hexadecimal string and in Base64. Hashing uses the browser’s native Web Crypto API, so even large files are hashed quickly without uploading them. SHA-1 is still used for Git object IDs and legacy checksums, but it is no longer collision-resistant, so use SHA-256 for security-sensitive purposes.

## How to use SHA-1 Hash Generator for Text and Files

1. **Choose text or file input** — Type text, or switch to File Input to hash a file.
2. **Get the hash** — The SHA-1 digest appears instantly in hex and Base64.
3. **Copy or compare** — Copy the hash or compare it with a published checksum.

## Frequently asked questions

### Is SHA-1 secure?

Not for signatures or certificates — practical collision attacks exist. It remains fine for non-security checksums and compatibility with older systems.

### Why does my hash differ from another tool?

Hashes change with any difference in input, including a trailing newline, different line endings or text encoding. This tool hashes UTF-8 text exactly as typed.

### Are files uploaded to be hashed?

No. The file is read and hashed locally with Web Crypto.
