What this tool does
Generate SHA-1, SHA-256, SHA-384, or SHA-512 hashes from text. Processing is completed directly in your browser.
How to use it
- Enter the text you want to hash.
- Choose SHA-1, SHA-256, SHA-384, or SHA-512.
- Click “Hash Generator” to calculate the hash.
- Copy the resulting hash value.
Supported input and notes
The same text produces the same hash, but a hash cannot be decoded to recover the text. This tool hashes typed or pasted text, not uploaded files. Spaces and line breaks affect the result.
When it is useful
Useful for comparing the hash of text snippets or producing a fixed-length digest for development tasks.
The Same Text Produces the Same Hash
Using the same hash method on exactly the same text produces the same result each time. This makes hashes useful when comparing whether two text inputs are identical.
Same Input
The same method and exactly the same text produce the same hash value.
Changed Input
Changing case, spaces, or line breaks normally produces a very different hash value.
Spaces and Line Breaks Matter
Text that looks almost identical can still hash differently when a trailing space or line break is present. Check for hidden whitespace when two values do not match as expected.
Different Methods Produce Different Lengths
This tool supports SHA-1, SHA-256, SHA-384, and SHA-512. The selected method changes both the output value and its length, so use the method required by the system you are working with.
Hashing Is Not a Reversible Conversion
A hash is not designed to reveal the original text from the generated value. If you need to restore and read the original content later, hashing serves a different purpose.
Hashing and Base64 serve different purposes: Base64 encode/decode can restore the original text, while a hash is better understood as a value used for comparison or identification.
Use a Password-Specific Method for Storage
Hashing a password once with a general SHA method is not considered sufficient protection for password storage. Real services should use a security method designed specifically for storing passwords.
FAQ
Does changing one character change the result?
Yes. Differences in text, including spaces, line breaks, and letter case, normally produce a different hash.
Do SHA-1 and SHA-256 produce the same result?
No. Different methods produce different hash values.
Can I hash a file?
No. This page hashes text entered in the input area and does not select files for hashing.
