Hash Generator
The Hash Generator computes SHA-1, SHA-256, SHA-384, and SHA-512 digests of any text using your browser’s built-in cryptography. Use it to verify file integrity, compare checksums, or generate deterministic fingerprints — all live as you type, with nothing uploaded. Each algorithm produces a fixed-length digest no matter how much text you feed it — SHA-1 outputs 40 hex characters, SHA-256 outputs 64, and SHA-512 outputs 128 — so you can tell at a glance which algorithm produced a hash you're comparing against. Note this tool hashes text you type or paste, not uploaded files; to verify a downloaded file's checksum, generate the file's hash separately (e.g. with sha256sum) and compare the value here.
…………Computes SHA-1, SHA-256, SHA-384, and SHA-512 checksums of your text using your browser’s built-in cryptography — nothing is uploaded. Hashes update live as you type. (SHA-1 is shown for legacy compatibility; use SHA-256 or higher for security.)
How This Tool Works
Type or paste text and the SHA-1, SHA-256, SHA-384, and SHA-512 digests appear instantly. Click Copy next to any algorithm to copy its hash.
Formula & Method
A cryptographic hash function maps any input to a fixed-length hexadecimal digest. The same input always produces the same hash, while even a tiny change produces a completely different one — which is what makes hashes useful for integrity checks and fingerprints.
Example Calculation
Hashing “The quick brown fox” with SHA-256 always yields the same 64-character digest — change a single letter and the entire hash changes. Hashing "The quick brown fox jumps over the lazy dog" with SHA-256 always produces d7a8fbb307d7809469ca9abcb0082e4f8d5651e46d3cdb762d02d0bf37c9e592 — just adding a period at the end changes it completely to ef537f25c895bfa782526529a9b63d97aa631564d5d789c2b765448c8635fb6c, with no resemblance between the two.
Frequently Asked Questions
Which algorithms are supported?+
SHA-1, SHA-256, SHA-384, and SHA-512 — all computed with your browser’s SubtleCrypto API. MD5 isn’t included because it isn’t supported natively and is considered insecure.
Is my text sent to a server?+
No — hashing happens entirely in your browser, so your input never leaves your device.
Should I use SHA-1?+
Only for legacy compatibility. SHA-1 is no longer considered collision-resistant, so use SHA-256 or higher for anything security-related.
Can I use this to check a downloaded file's checksum?+
Not directly — this tool hashes text you type or paste, not files you upload. Generate the file's hash with a command-line tool (like sha256sum on Mac/Linux or CertUtil on Windows), then compare that output against the value here or against what the file's publisher posted.
Can I use these hashes to store passwords?+
No — a raw SHA-256 or SHA-512 hash of a password is fast to compute, which makes it vulnerable to brute-force and rainbow-table attacks. Passwords should be stored with a purpose-built, deliberately slow algorithm like bcrypt, scrypt, or Argon2, none of which this tool provides.
