Overview
Compute MD5, SHA‑1, and SHA‑256 hashes for checksums, debugging signatures, and comparing content quickly. Great for verifying that two strings are identical (including whitespace). Runs locally in your browser.
Pro time-savers
- Per-line batch hashes (tabular output)
Use cases
- Verify a checksum for a text payload in debugging.
- Compare two strings quickly by comparing hashes.
- Generate a stable identifier for non-security uses (deduping).
Common pitfalls
- Hidden CRLF vs LF line endings often cause different hashes.
- Hashing is not signing; it does not prove authenticity without a secret key (HMAC).
FAQs
Is MD5 secure?
No. MD5 is broken for collision resistance. Use SHA‑256 for security-sensitive cases.
Why do I get different hashes for “the same text”?
Hidden whitespace/newlines are usually the cause. Normalize your input (trim, remove CRLF) and try again.
Can I hash files?
This tool focuses on text inputs. For large files, use a file hashing tool/CLI.
Is hashing encryption?
No. Hashing is one-way; encryption is reversible with a key.
