A hash generator converts any input text or file into a fixed-length string called a hash or digest. Hash functions are one-way — you cannot recover the original input from the hash. This makes them ideal for verifying data integrity, storing passwords securely, and generating checksums. The ToolForge Hash Generator supports MD5, SHA-1, SHA-256, SHA-384, and SHA-512 — all computed entirely in your browser using the Web Crypto API.

Learn how cryptographic hash functions work and compare algorithm outputs.
A cryptographic hash function takes an arbitrary amount of data and produces a fixed-size output called a digest or hash. The same input always produces the same output (deterministic), but even a single character change in the input produces a completely different hash (avalanche effect). This makes hash functions useful for detecting tampering.
SHA-256 is the workhorse of modern cryptography — it is used to secure Bitcoin transactions, TLS certificates, JWT signatures, and API authentication. SHA-512 is similarly secure but produces a longer output, which is useful when extra security margin is required. For file integrity verification (checksums when downloading software), SHA-256 or SHA-512 are the standard recommendations.
MD5 and SHA-1 are considered cryptographically broken and should not be used for security-sensitive applications. Both are vulnerable to collision attacks — two different inputs that produce the same hash — which can be exploited to forge digital signatures. However, they remain widely used for non-security purposes like file deduplication and caching.
For password storage, none of these algorithms should be used directly. Passwords require specialized algorithms like bcrypt, scrypt, or Argon2, which are intentionally slow and include salting to prevent rainbow table attacks.
MD5 is no longer considered secure for cryptographic purposes like password hashing or digital signatures because it is vulnerable to collision attacks. However, MD5 is still widely used for non-security purposes such as file integrity checks, checksums, cache keys, and deduplication. For security-sensitive applications, use SHA-256 or SHA-512 instead.
No. Hash functions are one-way by design — the original input cannot be recovered from the hash output. This is fundamentally different from encryption, which is reversible with a key. To verify data, you hash the input again and compare both hashes.
A checksum is a hash value used to verify the integrity of a file or data. Software publishers provide SHA-256 checksums alongside downloads. You generate the hash of your downloaded file and compare it to the published value — a match confirms the file is intact.
None of the algorithms in this tool are appropriate for passwords. Use bcrypt, scrypt, or Argon2 — these are intentionally slow and include salting to resist brute-force attacks. MD5 and SHA-256 are too fast for password security.
