How to use SHA256 / SHA512 Generator

Steps

Paste text to hash.
Choose SHA-256, SHA-384 or SHA-512.
Choose uppercase output if needed.
Copy the generated digest.

Common use cases

Integrity checks: Create digests for comparing text values.
Technical docs: Show example hashes in documentation.
Security testing: Compare hash algorithms in non-production workflows.

Good to know

SHA-256 and SHA-512 are cryptographic hash functions that create fixed-length digests from input text or bytes.

FAQ

Frequently asked questions

Is SHA256 better than MD5?

SHA-256 is more appropriate for modern integrity checks than MD5.

Can I store passwords with SHA256 alone?

No. Password storage should use dedicated algorithms such as Argon2, bcrypt or scrypt with salts.

Is a hash reversible?

A cryptographic hash is designed to be one-way, unlike encoding such as Base64.

Are my inputs sent to a server?

OnSubmit tools run in the browser whenever the task can be processed locally. Avoid pasting production secrets, real banking details or personal data into public tools.
