Hash Generator

A hash generator computes a fixed-length fingerprint, called a digest, from any input text using a one-way cryptographic hash function. The same input always yields the same digest, even a one-character change produces a completely different output, and you cannot reverse the digest back into the original text. Xevon Tools' Hash Generator supports four widely used functions: MD5 (128-bit, 32 hex characters), SHA-1 (160-bit, 40 characters), SHA-256 (256-bit, 64 characters), and SHA-512 (512-bit, 128 characters). The SHA family is computed through the browser's native Web Crypto API, which is fast and standards-compliant. Choosing the right algorithm matters. SHA-256 and SHA-512 are the current standard for integrity and security work: use them to verify downloads or to build security features. MD5 and SHA-1 are cryptographically broken, meaning researchers can deliberately construct two different inputs with the same hash, so they must never be relied on to detect tampering by an attacker. They are still genuinely useful for non-adversarial tasks such as checksums against accidental corruption, cache-busting keys, and matching identifiers in legacy databases. One important nuance: hashing is not the same as password storage. A bare SHA-256 of a password is fast to brute-force, so production systems should use a deliberately slow, salted algorithm like bcrypt, scrypt, or Argon2 instead. Because every computation happens in your browser, sensitive inputs such as keys or private strings never reach a server, which is the whole point when you are checking a value you would not paste into a remote tool. The output is lowercase hex with one-click copy, ready to drop into a checksum file, a verification script, or documentation.
