About MD5

MD5 produces a 128-bit digest, written as 32 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 32 characters long, as expected for MD5.

Security: MD5 is cryptographically broken — practical collisions have been demonstrated since 2004. It is fine for non-security checksums and deduplication, but should never be used for passwords, signatures, or any security-sensitive purpose. It is most appropriate for file checksums and non-security deduplication.

Can this hash be reversed?

Hashing is one-way — you cannot mathematically reverse a MD5 hash to recover its input. However, precomputed (rainbow) tables can simply look up the hashes of common inputs, so a common dictionary word like "root" should never be used as a password. Strong passwords are long, random, and salted before hashing.

Frequently Asked Questions

What is the MD5 hash of "root"?▾

The MD5 hash of "root" is 63a9f0ea7bb98050796b649e85481845.

Is MD5 secure?▾

MD5 is cryptographically broken — practical collisions have been demonstrated since 2004. It is fine for non-security checksums and deduplication, but should never be used for passwords, signatures, or any security-sensitive purpose.

How long is a MD5 hash?▾

A MD5 hash is 128-bit, which is 32 hexadecimal characters long.

Can a MD5 hash be reversed?▾

No. MD5 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 "root" should never be used as a password.
