SHA-256 Hash Generator — Create Secure Hashes Instantly
SHA-256 is a widely trusted cryptographic hash function. Generate a SHA-256 hash from any text in one click.
SHA-256 is part of the SHA-2 family of cryptographic hash functions and produces a 64-character hexadecimal hash from any input. It's widely used in security applications, blockchain technology, digital signatures, and file integrity verification because it's currently considered cryptographically secure.
Our SHA-256 Generator computes the SHA-256 hash of any text you provide, instantly and locally in your browser.

Frequently Asked Questions
Is SHA-256 secure?
Yes, SHA-256 is currently considered cryptographically secure and is widely used in security-sensitive applications, including TLS certificates and Bitcoin's blockchain.
Can I reverse a SHA-256 hash back to the original text?
No, like all cryptographic hash functions, SHA-256 is a one-way function — it's computationally infeasible to reverse the hash to retrieve the original input directly.
Should I use SHA-256 to store passwords?
Plain SHA-256 is better than MD5 for hashing, but for password storage specifically, purpose-built algorithms like bcrypt, scrypt, or Argon2 are recommended, as they include features like salting and configurable work factors that resist brute-force attacks better.
Will the same input always produce the same SHA-256 hash?
Yes, SHA-256 is deterministic — identical input will always produce the identical 64-character hash output.
