Why Choose WebToolsHub Hash Generator?
Many online hash tools only support one algorithm or require software installation. WebToolsHub provides a free browser-based Hash Generator supporting SHA-1, SHA-256, SHA-384, and SHA-512 in one place. Generate secure hash values instantly while keeping your data private during processing.
How to Generate Hash Values Online
Enter your text
Paste or type the text you want to hash.
Select the hash algorithm
Choose SHA-1, SHA-256, SHA-384, or SHA-512 depending on your development, verification, or security requirements.
Copy your generated hash
Generate the hash instantly, copy the output with one click, and use it for file verification, authentication, APIs, or development projects.
What a hash is
Any text becomes a short fixed-length fingerprint. The same text always gives the same hash, and a tiny change gives a completely different one.
Which hash for which job
A longer hash is harder to forge. Pick the strongest one the other side accepts.
| Algorithm | Length | Use it for |
|---|---|---|
| SHA-1 | 160 bits · 40 characters | Old systems only. Not safe against deliberate forgery. |
| SHA-256 | 256 bits · 64 characters | The standard choice: file checksums and integrity checks. |
| SHA-384 | 384 bits · 96 characters | When a longer hash is required. |
| SHA-512 | 512 bits · 128 characters | The longest and strongest here. |
A plain hash is quick to guess. Websites should store passwords with a slow, salted method instead.
The word “hello” in each algorithm
| Algorithm | Starts with | Notes |

| SHA-1 | aaf4c61ddcc5e8a2… | 40 hex characters |
| SHA-256 | 2cf24dba5fb0a30e… | 64 hex characters |
| SHA-384 | 59e1748777448c69… | 96 hex characters |
| SHA-512 | 9b71d224bd62f378… | 128 hex characters |
