SHA-256 Generator
Generate the SHA-256 hash of any text instantly. SHA-256 is a cryptographic hash function that produces a fixed 64-character digest, widely used in TLS, blockchain, file verification and password storage.
It is completely free, private and requires no signup.
You cannot recover the original input from a hash.
bcrypt or argon2 for passwords; SHA-256 for integrity.
Compare digests for integrity; prefer slow algorithms for secrets.
How it works
Generate the SHA-256 hash of any text instantly. SHA-256 is a cryptographic hash function that produces a fixed 64-character digest, widely used in TLS, blockchain, file verification and password storage.
Enter any text, password or file content. The hash updates in real time.
The 64-character hexadecimal digest is shown. Even a tiny change in input completely changes the output.
Examples & Data
| Input | SHA-256 |
|---|---|
| hello | 2cf24dba5fb0a30e26e83b2ac5b9e29e1b161e5c1fa7425e73043362938b9824 |
| Hello | 185f8db32271fe25f561a6fc938b2e264306ec304eda518007d1764826381969 |
Notice how "hello" and "Hello" produce completely different hashes.

Yes. SHA-256 is collision-resistant and cryptographically secure, used in TLS certificates, Bitcoin and file integrity verification.
No. Hashing is one-way. You cannot recover the original input from the digest.
For password storage prefer bcrypt or argon2, which are slow and salt automatically. SHA-256 alone is too fast for passwords.
