About this tool
Cryptographic hash functions produce a fixed-length digest from any input. MD5 is available via a pure-JS implementation. SHA-256 and SHA-512 are widely used for data integrity verification and use the browser's SubtleCrypto API. All hashing happens entirely in your browser — your input never leaves your device.
Runs in your browser — nothing is uploaded; your input never leaves your device. How it works
Quick answer
Type or paste any text and Tabreon instantly computes its MD5, SHA-1, SHA-256, SHA-384, and SHA-512 hashes side by side — all in your browser.
Why use Tabreon for this?
All five hash algorithms are computed at once, so you can compare or pick the one you need without re-running the tool.
SHA-1 through SHA-512 use your browser's built-in SubtleCrypto API; hashing happens entirely on-device.
No account, no limit on how much text you can hash.
How to hash text
1Enter your text. Type or paste the text you want to hash.
2Review all five hashes. MD5, SHA-1, SHA-256, SHA-384, and SHA-512 digests appear together, updating as you type.
3Copy the one you need. Copy the specific hash your use case requires.
What is a cryptographic hash?
A cryptographic hash function takes any input and produces a fixed-length string of characters (the "digest") that's effectively unique to that input — changing even one character in the input produces a completely different hash. Hashes are one-way: you can't recover the original text from the hash. They're used to verify data hasn't been altered, to store passwords without keeping the plaintext, and to generate short fingerprints for large files.
How Tabreon handles your data
SHA-family hashes are computed in your browser via the native SubtleCrypto API, and MD5 via a local JavaScript implementation — the text you hash is never transmitted anywhere.
Key features
Five algorithms computed simultaneously: MD5, SHA-1, SHA-256, SHA-384, SHA-512
SHA-family hashes computed via the browser's native SubtleCrypto API
Live results as you type
Copy-to-clipboard for each hash independently
Common use cases
Verifying a downloaded file's integrity against a published SHA-256 checksum
Generating a fingerprint of a config or text file to detect changes
Producing a non-reversible reference value for a piece of text in a log or database
Common mistakes & limitations
MD5 and SHA-1 are considered cryptographically broken for security purposes (e.g. password storage or digital signatures) — use SHA-256 or higher where security matters; MD5/SHA-1 here are for checksums and legacy compatibility.
Hashing very large text (many megabytes) may be slower since it runs in your browser tab rather than on dedicated hardware.
Frequently asked questions
No. All five hashes are computed locally in your browser using the Web Crypto API (and a local MD5 implementation) — nothing is transmitted to a server.
For anything security-sensitive, use SHA-256 or higher — MD5 and SHA-1 are fast to attack with modern hardware. MD5 and SHA-1 are still useful for quick checksums or matching legacy systems.
