What is SHA Hash Generator?

SHA Hash Generator is a tool for hashing text with SHA-256, SHA-384, or SHA-512. It encodes the input as UTF-8 and shows the result in both HEX and Base64 formats. That makes it useful for content comparison, integrity checks, and verification work.

You can also load a text file from the input toolbar and hash its contents as text. Everything runs in the browser, so it is handy when you want to check sample text, notes, or config snippets without sending them anywhere.

How to Use

1. Enter the text you want to hash.
2. Choose SHA-256, SHA-384, or SHA-512.
3. Choose whether the HEX output should use lowercase or uppercase letters.
4. The HEX and Base64 values update automatically in the result fields.
5. Copy either result when you need it for comparison or documentation.

If you want to use a text file, load it from the toolbar above the input area. The loaded file is handled as text content.

Algorithm Differences

SHA-256

This is the most practical default for general use. It fits everyday checks such as comparing text, reviewing configuration changes, and confirming expected hash output in development workflows.

SHA-384

This produces a longer hash than SHA-256. It works well when you want more output length than SHA-256 without going all the way to SHA-512.

SHA-512

This produces the longest hash of the three options. The output is larger, but it can be useful when you explicitly need a longer hash value.

Use Cases

• Comparing whether two pieces of text are identical
• Checking whether config content or notes have changed
• Reviewing hash values before implementing verification logic
• Confirming expected SHA output from sample text data

Example Output

Things to Keep in Mind

• This tool hashes text input, not raw binary files such as images or PDFs
• Loaded files are processed as text, so encoding or line ending differences can change the result
• A hash value is not something you can decode back into the original text
• Changing HEX letter case does not change the hash itself. It only changes how the letters are displayed
• For password storage, dedicated algorithms such as bcrypt or Argon2 are generally more appropriate than plain SHA hashing
