Hash Generator
Enter any text to compute MD5, SHA-1, SHA-256, and SHA-512 hashes simultaneously. Uses the Web Crypto API for SHA hashes. All processing happens in your browser — no data is sent to a server.

How to Use the Hash Generator
Type or paste text into the input field. All four hash algorithms (MD5, SHA-1, SHA-256, SHA-512) compute simultaneously and display their results below. Click the Copy button next to any hash to copy it to your clipboard.
What Are Hash Functions?
A cryptographic hash function takes any input and produces a fixed-length string of hexadecimal characters. The same input always produces the same hash, but even a tiny change in the input produces a completely different hash. Hash functions are one-way — you cannot reverse a hash to get the original input.
MD5 produces a 128-bit (32 character) hash. It is fast but considered cryptographically broken — use it only for checksums and non-security purposes. SHA-1 produces a 160-bit (40 character) hash. Also deprecated for security use but still common in legacy systems. SHA-256 and SHA-512 are part of the SHA-2 family and are widely used for security, digital signatures, and blockchain applications.
Privacy
SHA hashes are computed using the Web Crypto API (crypto.subtle.digest). MD5 is computed using a local JavaScript library. All processing happens in your browser — no data is ever sent to a server.
