Hash King - Hash Generator

Hash King is a fast, all-in-one hashing toolkit for anyone who needs to generate, verify, or compare checksums, digests, keyed hashes, or password hashes - developers, sysadmins, students, and security-conscious users alike. Everything runs on your device; your text and files are never uploaded anywhere to be hashed.

HASH TEXT OR FILES

Type or paste any text, or pick a file, and instantly get its hash in your choice of over 40 algorithms:

• Modern cryptographic: SHA-256, SHA-384, SHA-512, SHA3-224/256/384/512, SHAKE128/256, BLAKE2b, BLAKE2s, BLAKE3, SM3, RIPEMD-160

• Legacy (flagged so you know it's not collision-resistant): MD5, MD4, MD2, SHA-1, NTLM, RIPEMD-128

• Checksums: CRC-8/16/32/32C/64, Adler-32, BSD Checksum, Fletcher-16/32

• Fast non-cryptographic hashing: FNV-1/1a (32 & 64-bit), xxHash (XXH32/XXH64), Pearson

Algorithms are grouped and searchable, with a clear warning badge on anything that's broken or obsolete for security-sensitive use - so you're never guessing which one is actually safe to rely on.

VERIFY DOWNLOADS AND INTEGRITY

Paste an expected hash right on the File screen and get an instant match/mismatch check - the everyday reason most people reach for a hash tool in the first place. The Compare screen also gives you a full hash-vs-hash comparison with a character-by-character diff.

HMAC (KEYED HASHING)

Generate HMAC-MD5/SHA1/SHA256/SHA384/SHA512 to prove both integrity and authenticity with a secret key - the standard way to sign API requests and webhooks.

PASSWORD HASHING (KDF)

A dedicated tool for the algorithms actually meant for passwords, not files: PBKDF2-HMAC-SHA256, BCrypt (with built-in verification), scrypt, and Argon2id. These are deliberately slow and salted, unlike a plain hash.

BATCH FILE HASHING

Hash a whole folder of files in one pass, then share the results or export them as CSV.

MORE TOOLS

• Output in hex or Base64

• Generate a QR code from any result for quick sharing/verification

• Full calculation history, searchable and exportable

• Share text or a file straight into Hash King from any other app

• Light/dark theme with optional Material You dynamic color

Hash King Pro removes all ads and unlocks batch hashing and history export, as a one-time purchase - no subscription.

Whether you're checking a download's integrity, signing an API request, hashing a password the right way, or just need a quick MD5/SHA-256 for a text string, Hash King has it covered in one clean, fast app.
