The SHA-512 Hash Generator on Developer Toolkit is a great tool to hash your text with the highest security option.
How It Works ?
- Input: Paste your text into the box.
- Options: You can select Hex or Array format.
- HMAC Support: Add a secret key if you need a keyed hash.
- Output: Hit the "Generate" button, and there’s your hash.
Example :
- Input
Hello, World! - Output (SHA-512)
374d794a95cdcfd8b35993185fef9ba368f160d8daf432d08ba9f1ed1e5abe6cc69291e0fa2fe0006a52570ef18c19def4e617c33ce52ef0a6e5fbe318cb0387
SHA-512 vs SHA-256
There are clearly big differences between those two and I am not mentioning about SHA1 here because these are the ones needs to be used if there is no need for legacy systems.
- SHA256 :
- 256 bits (64 hex chars).
- Decent for most use cases, faster on 32-bit systems.
- Example hash:
a591a6d40bf420404a011733cfb7b190d62c65bf0bcda32b56d4efaa4c7e72f7
- SHA512 :
- 512 bits (128 hex chars).
- More secure and efficient on 64-bit systems.
- Example hash:
861844d6704e8573fec34d967e20bcfe6e01b2ac418a7f83f8d8360cfd6dbaeae4e3f5a6e8b8e5f0f3c7d5b0a3a1e6a2c3e0d3e4f5a6b7c8d9e0f1a2b3c4d5e6
If you’re working on something that needs long-term security (e.g., sensitive data or cryptographic stuff), go with SHA-512. Otherwise, SHA-256 is fine for most apps.
HMAC? Yeah, That’s Here
This tool also supports HMAC. That’s when you hash your data with a secret key. It’s essential if you’re doing API auth or verifying data integrity.
Example with HMAC-SHA-512 :
- Input: Hello, World!
- Key: mysecretkey
- Output:
2cf4f8fedc518a49eb5a2a450d2a6b211ccce7063dd857e1a1a36f18a9b3e8a22f180b38a55bd1d97b782052c2073709c551cbc6e0822b78386fe31d02453ba1
At the end
- Use SHA-512 for more security, SHA-256 if you need speed.
- Add HMAC if you’re dealing with secret keys (like signing API requests).
- The tool is dead simple—hash your stuff and move on.
