Generate MD5, SHA-256, SHA-512, and more hashes instantly
Free online hash generator. Create MD5, SHA-1, SHA-224, SHA-256, SHA-384, and SHA-512 cryptographic hashes from any text. All hashing is done locally in your browser.
A cryptographic hash function takes an input and produces a fixed-length string of bytes. The same input always produces the same hash, but even a tiny change to the input produces a completely different hash.
For security, use SHA-256 or SHA-512. MD5 and SHA-1 are cryptographically broken and should only be used for checksums or non-security purposes. SHA-256 is the current industry standard.
No. Cryptographic hash functions are one-way. You cannot reverse-engineer the original input from the hash. This is what makes them useful for password storage and data integrity.
MD5 produces a 128-bit (32 hex character) hash and is fast but cryptographically broken. SHA-256 produces a 256-bit (64 hex character) hash and is considered secure for most applications.
No. All hashing is done locally in your browser using the CryptoJS library. Your data never leaves your device.
