Calculate SHA2 Hash – SHA-224, SHA-256, SHA-384, SHA-512 | Free Tool
Compute the full SHA-2 family (SHA-224, SHA-256, SHA-384, SHA-512) from text in one place. Client-side only. The standard for secure hashing.
What is the SHA2 Hash tool?
This tool computes all four SHA-2 hashes (SHA-224, SHA-256, SHA-384, SHA-512) from the same text. SHA-2 is the standard family for secure hashing. All processing runs in your browser; your data never leaves your device.
Key features
- All SHA-2 variants — SHA-224, SHA-256, SHA-384, SHA-512 in one view.
- Client-side — No server uploads.
- UTF-8 input — Any text. One input, four hashes.
- Copy — One-click copy per hash.
How to use
- Open Calculate SHA2 Hash.
- Paste or type your text.
- Copy the hash(es) you need. Use SHA-256 for most cases; SHA-384 or SHA-512 for higher security.
When to use SHA-2
- Passwords — With proper salting and key derivation in your app.
- Certificates and TLS — SHA-256 or SHA-384.
- Integrity checks — File hashes, API signatures.
- Blockchain and signing — SHA-256 is common.
Frequently asked questions
What is SHA-2?
SHA-2 is a family of hashes: SHA-224, SHA-256, SHA-384, SHA-512. They are the standard for secure hashing.
What input does the tool accept?
Any text. Input is hashed as UTF-8. You get all four SHA-2 variants at once.
Which SHA-2 variant should I use?
SHA-256 is the most common. Use SHA-384 or SHA-512 for higher security. SHA-224 is less common.
Is my data sent to a server?
No. All hashing runs in your browser.
When should I use SHA-2?
For passwords (with proper salting), certificates, integrity checks, and any security-sensitive hashing.
Why do I get four hashes?
This tool shows the full SHA-2 family. Use the one your system or standard requires.
