Hash generator

Hash UTF-8 text with MD5, SHA-1, SHA-256, SHA-384, or SHA-512 and show the digest in hexadecimal.

The answer

The digest is the hexadecimal hash of the UTF-8 bytes. MD5 and SHA-1 are included because older systems still compare them. SHA-256 is the default for a new checksum.

Result

SHA256

What do you want to do next?

How this works

The hash covers the exact text in the box, including spaces and line breaks, encoded as UTF-8. A different line ending changes the digest.

MD5 and SHA-1 are broken for collision resistance. Use them to match a legacy checksum, not to sign something new. SHA-256, SHA-384, and SHA-512 are the stronger choices on this page.

Practical steps

  1. 1

    Paste the exact text, including any trailing line break the other system hashed.

  2. 2

    Choose the algorithm named by the checksum you are checking.

  3. 3

    Compare the hexadecimal digest. A single different character changes it.

Examples

  • MD5 of “hello”

    5d41402abc4b2a76b9719d911017c592

Common mistakes

  • ×

    Hashing text that gained or lost a trailing newline and expecting the published checksum to match.

Frequently asked questions

Is the hash a password hash?

No. There is no salt and no slow key derivation. Do not store these digests as passwords.

Does MD5 of an empty string have a known value?

Yes, but this form asks for text. An empty box is rejected so a blank paste is not mistaken for a checksum of nothing.
