Frequently asked questions
Does my text get uploaded anywhere?
No. Every hash is computed locally in your browser tab. Your text never leaves your device or gets sent to a server.
Why is MD5 included when it's considered cryptographically broken?
MD5 is still widely used for non-security purposes like file-integrity checksums and quick deduplication, so it's included here for compatibility. It is not recommended for anything security-sensitive — use SHA-256 or stronger for passwords, signatures, or other security-critical purposes.
Is there a limit to how much text I can hash?
No hard limit is enforced, but very large input (many megabytes of text) may take noticeably longer to hash and could briefly slow down your browser.
Are hashes case-sensitive to my input text?
Yes. Hash functions are extremely sensitive to their input — changing even a single character, adding whitespace, or altering capitalization produces a completely different, unrelated-looking hash.
Does this tool store or log what I type?
No. Nothing is stored, logged, or transmitted. All computation happens locally in memory in your browser tab and disappears when you close or refresh the page.
