SHA256 Hash Tool
Generate and verify SHA-256 digests for integrity workflows
9 free tools
Cryptographic hash functions convert any input into a fixed-length fingerprint that cannot be reversed. Our free online hash tools let you generate MD5 checksums, SHA-256 and SHA-512 hashes, HMAC signatures, Bcrypt password hashes, and CRC32 checksums — and verify file integrity by comparing hash values, all entirely in your browser.

MD5 and SHA-1 are older and faster but considered cryptographically broken for security use. SHA-256 (part of SHA-2) is the current standard for digital signatures and data integrity. Use SHA-256 or SHA-512 for any security-sensitive hashing.
No. Hash functions are one-way by design. You cannot reverse a hash to get the original input. This is what makes them useful for password storage — even if the hash leaks, the original password stays safe.
