What is the Hash Generator Tool?#
The Hash Generator Tool computes hash values from text. Type or paste your text and all supported algorithms are calculated at once, ready to copy in the format you need.
A hash value is a fixed-length string derived from the input. It is commonly used to check that content has not changed, or to pass a digest to an API.
How to Use#
- Type or paste the text you want to hash.
- Copy the hash value you need.
You can switch the output format between lowercase hex, uppercase hex, and base64. The default is lowercase hex.
Supported Algorithms#
| Algorithm | Hex length | Use |
|---|---|---|
| SHA-256 | 64 | The default choice for checksums and general use |
| SHA-512 | 128 | A stronger SHA-2 variant with a longer output |
| SHA-384 | 96 | A stronger SHA-2 variant with a longer output |
| SHA-1 | 40 | Legacy; kept for checking existing values. Do not use where security matters |
| MD5 | 32 | Legacy; kept for checking existing values. Do not use where security matters |
Common Use Cases#
- Check a checksum of a piece of text without leaving the browser.
- Get a digest to send with an API request.
- Compare values while debugging, across environments or implementations.
Frequently Asked Questions#
No. Everything runs in your browser, and your text is not uploaded anywhere.
Yes, but only to verify values made in the past. Both are broken against deliberate tampering, so SHA-256 or stronger is the better choice for anything security-sensitive.
No. This tool hashes text only. To hash a file, use a command-line tool or a dedicated file utility on your device.
Yes. Every character, including line breaks and trailing spaces, is part of the input. Even one extra character produces a completely different value.
It represents the same digest bytes in a compact text form. Some APIs and configuration formats expect digests as base64 rather than hex.
Notes#
- Input is hashed as UTF-8. The same text always produces the same value here, but systems using a different encoding may produce different values.
- Hashing is one-way. A hash value cannot be turned back into the original text.
