About SHA-1

SHA-1 produces a 160-bit digest, written as 40 hexadecimal characters. The same input always produces the same hash, while even a one-character change yields a completely different output. This page's hash is exactly 40 characters long, as expected for SHA-1.

Security: SHA-1 is deprecated — a practical collision was demonstrated in 2017 (the SHAttered attack). Avoid it for any new security use; migrate existing systems to SHA-256 or stronger. It is most appropriate for legacy compatibility only, not new security uses.

Can this hash be reversed?

Hashing is one-way — you cannot mathematically reverse a SHA-1 hash to recover its input. However, precomputed (rainbow) tables can simply look up the hashes of common inputs, so a common dictionary word like "world" should never be used as a password. Strong passwords are long, random, and salted before hashing.

Frequently Asked Questions

What is the SHA-1 hash of "world"?▾

The SHA-1 hash of "world" is 7c211433f02071597741e6ff5a8ea34789abbf43.

Is SHA-1 secure?▾

SHA-1 is deprecated — a practical collision was demonstrated in 2017 (the SHAttered attack). Avoid it for any new security use; migrate existing systems to SHA-256 or stronger.

How long is a SHA-1 hash?▾

A SHA-1 hash is 160-bit, which is 40 hexadecimal characters long.

Can a SHA-1 hash be reversed?▾

No. SHA-1 is a one-way function, so a hash cannot be mathematically reversed back to its input. However, hashes of common inputs can be looked up in precomputed (rainbow) tables — which is why a common word like "world" should never be used as a password.
