Frequently Asked Questions
Which hash algorithms are supported?
MD5, SHA-1, SHA-256, and SHA-512. Each produces a fixed-length hash string — MD5 (32 hex chars), SHA-1 (40), SHA-256 (64), SHA-512 (128).
Can I hash files, not just text?
Yes. Paste text or upload a file. The tool computes the hash of the file contents using the CryptoJS library entirely in your browser.
What's the difference between MD5 and SHA-256?
MD5 is faster but cryptographically broken — vulnerable to collision attacks. SHA-256 is secure and recommended for password hashing, digital signatures, and data integrity checks.
Are the hashes salted?
No. This tool computes raw hashes. For password hashing, you should add a random salt before hashing and use a slow algorithm like bcrypt or Argon2 instead.
Is my input data uploaded?
No. Hashing happens entirely in your browser using CryptoJS. Neither your text nor file contents are transmitted to any server.
What happens with empty input, and are there options?
Empty or whitespace-only input only toasts 'Please enter input text' - nothing computes. There are no salt, iteration, encoding or file-picker options in this tool: one button runs all 4 CryptoJS digests (MD5, SHA-1, SHA-256, SHA-512) over the textarea verbatim.
