Hash text & files with MD5, SHA-256, HMAC, PBKDF2 & 40+ algorithms. Free.
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.
