Generate MD5, SHA-1, SHA-256, and SHA-512 hash values from text. Useful for checksums and data integrity.
Want to jump straight in? Use our free Hash Generator tool directly.
Navigate to the Hash Generator on UtilsNow. Generate cryptographic hashes entirely in your browser.
Type or paste the text you want to hash. Even a tiny change in input produces a completely different hash.
Select the algorithm: MD5 (fast, legacy), SHA-1 (legacy), SHA-256 (recommended), or SHA-512 (strongest).
The tool instantly generates the hash value as a hexadecimal string. The output length depends on the algorithm chosen.
Copy the hash value for use in checksum verification, data integrity checks, or API authentication.

Open Hash GeneratorUse SHA-256 for general purposes. MD5 and SHA-1 are considered cryptographically broken and should not be used for security. They are still fine for checksums.
No, hash functions are one-way. You cannot reverse a hash to recover the original input. This is by design for security purposes.
This is called the "avalanche effect." Even changing one character produces a completely different hash, making hashes useful for detecting data tampering.
