Generate a text hash safely
Create MD5, SHA-1, SHA-256, SHA-384, and SHA-512 digests from text. A hash is a fixed-length fingerprint: the same input produces the same digest, while even a small edit changes the result.
Step by step
- Enter the exact text you want to hash.
- Choose and copy the digest required by your system.
- Compare hashes only when both inputs use the same algorithm and text encoding.
Common uses
- Create cache keys or stable identifiers from non-sensitive text.
- Verify that two copied text values are identical.
- Test integrations that require sample hash values.
Good to know
A hash is not encryption and cannot be decrypted. MD5 and SHA-1 are vulnerable to collisions and should not protect passwords or security-sensitive data. Use a dedicated password-hashing function such as Argon2, scrypt, or bcrypt for stored passwords.
Frequently asked questions
Can I recover text from its hash?
No. Cryptographic hashes are one-way functions, although weak or common inputs may be guessed with lookup tables or brute force.
Is the input uploaded?
No. SHA calculations use the browser Web Crypto API and MD5 is also computed locally.
