SHA-256 Hash Generator
Create a SHA-1, SHA-256 or SHA-512 hash of any text. Runs in your browser; hashing is not encryption.
What is the SHA-256 Hash Generator?
The hash generator computes a SHA-1, SHA-256 or SHA-512 digest of the text you enter and shows it in hexadecimal. Hashing is a one-way fingerprint, not encryption, so the original text cannot be recovered from it. It is useful for checking file or text integrity. Everything runs in your browser.
How to use it
- Type or paste your text.
- Choose SHA-1, SHA-256 or SHA-512.
- Copy the hexadecimal digest.
SHA-256 Hash Generator — FAQ
Is hashing the same as encryption?
No. Encryption can be reversed with a key, while a hash is a one-way fingerprint. The same input always gives the same hash.
Which algorithm should I use?
SHA-256 or SHA-512 for integrity checks. SHA-1 is considered weak against deliberate attacks and is offered for compatibility only.
Can I store passwords as plain SHA-256?
It is not recommended. Passwords should be stored with a slow, salted method designed for the purpose, chosen with the help of a security professional.
