Standard 64-char Hex Output
- Enter Text: Type or paste your text into the input field.
- Generate: The tool automatically computes the hash as you type (or click generate if manual mode is active).
- Copy: Click the copy button to save the 64-character hash string to your clipboard.
- Privacy First: Operations run entirely in your browser using the Web Crypto API.
- Real-time Feedback: See the hash update instantly as you modify your input.
- Standard Compliance: Generates standard, industry-compliant SHA-256 hashes.
- Responsive Design: Works perfectly on desktop, tablet, and mobile devices.
- Security Verification: Quickly verify data integrity by comparing hashes.
- Password Hashing: Understand how modern systems store passwords (though real implementations use salt + iterations).
- Educational: Learn about cryptographic hash functions by experimenting with different inputs.
- Is my data secure?
Yes, absolutely. The hashing is performed locally in your browser using the Web Crypto API. Your input text is never sent to any server.
- Can I hash files?
Currently, this simplified tool is optimized for text input. For file hashing, specialized tools are recommended, though the underlying technology is similar.
- Is SHA-256 reversible?
No, SHA-256 is a one-way cryptographic hash function. You cannot decrypt a hash back to its original text; you can only verify if a given text matches a known hash.
- What is the output length?
A SHA-256 hash is always 256 bits long, which is typically represented as a 64-character hexadecimal string.
