Generate SHA-1, SHA-256 and SHA-512 hashes from any text. Uses Web Crypto API — nothing sent to servers.
A hash generator converts any input text into a fixed-length string using a cryptographic algorithm. The same input always produces the same hash, but even a tiny change in the input produces a completely different hash. Hash generators are used for verifying file integrity, storing passwords securely, and digital signatures.
Type or paste your text into the input above and select SHA256. The hash is generated instantly in your browser using the Web Crypto API. You can also generate MD5, SHA1, SHA384, and SHA512 hashes — all free, no signup required.
MD5 produces a 128-bit hash — fast but not recommended for security. SHA256 produces a 256-bit hash and is the industry standard for security-sensitive use cases. SHA512 produces a 512-bit hash and offers the highest security. For passwords, always use bcrypt or Argon2 instead of plain hashing.

We appreciate your feedback and will look into it.A hash generator converts any input text into a fixed-length string using a hashing algorithm like MD5, SHA-1, or SHA-256. The same input always produces the same hash.
MD5 produces a 128-bit hash and is faster but less secure. SHA-256 produces a 256-bit hash and is recommended for security-sensitive applications like password hashing.
No. Hashing is a one-way function. You cannot reverse a hash to get the original input, which is why hashes are used to store passwords securely.
SHA-256 is used in SSL certificates, blockchain, password storage, file integrity verification, and digital signatures.
Yes. All hashing is performed in your browser using the Web Crypto API. No data is sent to any server.
