Text hash generator: MD5, SHA-1, SHA-256 and SHA-512
Calculate four digests of UTF-8 text locally. Check whitespace and newline differences with a known example and guidance on appropriate uses.

How to use
Hashes are one-way content checks. MD5 and SHA-1 are unsuitable for secure signatures. None of these fast hashes should be used directly for password storage.
Your input stays yours
Step by step
- Paste the text, retaining any intended whitespace and newlines.
- Choose Compute hashes to see hexadecimal output from four algorithms.
- Compare only when algorithm, input bytes and encoding are identical.
Known digest example
abcDo not append a newline. SHA-256 should be ba7816bf8f01cfea414140de5dae2223b00361a396177a9cb410ff61f20015ad.
Frequently asked questions
Can a digest be decrypted?
A digest is not reversible encryption and this tool does not recover the source. A matching digest is not proof that two inputs can never differ.
Why do similar-looking texts have different hashes?
Spaces, trailing newlines, CRLF/LF, case and Unicode representation change bytes. The tool encodes UTF-8 without first cleaning or normalizing the text.
Can I use these directly for password storage?
No. These are fast digest algorithms; password storage needs a dedicated scheme, such as appropriately configured Argon2id. MD5 and SHA-1 are also unsuitable for secure signature uses.
