Hash Generator
Generate MD5, SHA-1, SHA-256 and more — locally
Note: All hashing happens in your browser via WebCrypto — nothing is uploaded. MD5 and SHA-1 are fine for checksums but should not be used for passwords or security signatures.

MakeCard Hash Generator computes five popular cryptographic digests of any text at once — MD5, SHA-1, SHA-256, SHA-384, and SHA-512 — the moment you type or paste. MD5 is produced by a local implementation while the SHA family uses your browser's native WebCrypto API, so every digest is standards-exact and generated entirely on your device. Each hash row has its own Copy button, and hashes you generate are remembered locally so the companion Hash Decoder can recognize them later.
How to Use Hash Generator
- 1 Type or paste your text into the input box — hashing starts live with every keystroke.
- 2 Five digest rows appear: MD5, SHA-1, SHA-256, SHA-384, and SHA-512.
- 3 Click "Copy" beside any algorithm to place that hex digest on your clipboard.
- 4 Open the "Hash Decoder" link if you later need to reverse-lookup a hash you generated here.
Key Features & Capabilities
- Five algorithms in one view: MD5, SHA-1, SHA-256, SHA-384, SHA-512.
- Live generation on input — no button press needed.
- Native WebCrypto for SHA digests; pure-JS MD5 for legacy checksums.
- One-click copy per hash value.
- Generated hashes saved locally to feed the Hash Decoder's instant-lookup.
- 100% client-side — text and digests never leave the browser.

Practical Everyday Use Cases
- Generating an MD5 or SHA-256 checksum to verify a downloaded file.
- Producing a consistent hash of an API key or token for logging comparisons.
- Creating SHA-256 digests for data-integrity checks in scripts.
- Teaching or demonstrating how hash lengths differ across algorithms.
- Testing whether two strings collide on a digest before using it as a key.
Pro Tips for Best Results
- Prefer SHA-256 or SHA-512 for anything security-relevant — MD5 and SHA-1 have known collision attacks.
- Hashing is one-way: there is no decryption, only guessing — use the Hash Decoder for that.
- MD5 and SHA-1 remain fine as file checksums for corruption detection, just not for password storage.
- Trailing spaces and newlines change the digest completely — copy text exactly when comparing hashes.
Common Problems & Solutions
Check for hidden characters — a trailing newline, different Unicode normalization, or UTF-16 vs UTF-8 input all produce different digests on the "same" text.
This tool covers MD5 and the SHA-2 family. For bcrypt, scrypt, Argon2, or HMAC, use a dedicated crypto library — those are deliberately different designs.
Privacy & Security
100% Client-Side Execution
All hashing happens in your browser via WebCrypto and local code — the text and its digests are never uploaded, logged, or stored on a server.
Frequently Asked Questions
Everything you need to know about using Hash Generator
MD5 produces a 32-hex-digit (128-bit) digest and is fast but cryptographically broken; SHA-256 gives 64 hex digits (256-bit) and is the current security standard. Use SHA-256 for integrity or signatures.
No — hashes are one-way functions. The only "reverse" is guessing inputs and comparing, which is what our Hash Decoder tries with common values.
For testing, yes — nothing leaves your browser. But real password storage should use bcrypt, scrypt, or Argon2, which are deliberately slow, rather than a fast digest like MD5 or SHA.
They remain useful as quick checksums to detect accidental file corruption — just never for security purposes where an attacker can craft colliding inputs.
