About Hash Generator

Cryptographic hash functions take an input of any size and produce a fixed-length output (digest). This tool supports MD5, SHA-1, SHA-256, and SHA-512. SHA-256 and SHA-512 use the browser's built-in Web Crypto API for fast, native performance. Hashing is a one-way operation — you cannot reverse a hash back to the original input.

Q: Which hash algorithm should I use?

For security purposes, use SHA-256 or SHA-512. MD5 and SHA-1 are considered cryptographically broken and should only be used for checksums or non-security purposes like cache keys.

Q: Can I decrypt a hash?

No. Hash functions are one-way by design — there is no mathematical way to reverse the process. Tools that "decrypt" hashes actually use precomputed lookup tables (rainbow tables).

Q: Why does MD5 produce a different result than other online tools?

Ensure you're comparing the same input encoding. This tool encodes input as UTF-8 before hashing. Some tools may use different encodings, which will produce different hash values for non-ASCII text.
