Text hash
MD5, SHA-1 and SHA-256
Generate MD5, SHA-1, and SHA-256 hashes from any text in real time. Used to verify data integrity, store passwords securely, and compare content without exposing the original. SHA-256 is the recommended standard for security.
How to use
- 1Type or paste the text you want to hash into the input field.
- 2The tool automatically calculates the MD5, SHA-1, and SHA-256 hashes in real time.
- 3Click the copy button next to the hash you need to use it wherever you want.
- 4Change the text at any time — all three hashes are recalculated instantly.
Practical examples
Verify a file's integrity
Generate the SHA-256 hash of the original content and compare it with the received file's hash — matching hashes mean nothing was changed.
Simulate password storage in tests
Use the hash of a test password to understand how it would be stored (in production, use libraries with salting, like bcrypt).
Compare two large texts quickly
Generate the hash of both — if they match, the texts are exactly identical, with no need to compare character by character.
Frequently asked questions
What is the difference between MD5, SHA-1 and SHA-256?
MD5 and SHA-1 are older and considered insecure for cryptographic use, but still useful for integrity checks. SHA-256 is the most secure and recommended for modern applications.
Can a hash be reversed to get the original text?
No. Hash functions are one-way by definition. There is no mathematical way to recover the original text from a hash.
Is the processing done in my browser?
Yes. All calculations happen locally on your device without sending the text to any external server.
