Hash Generator
Create cryptographic hashes from any text input.
Input
Hashes run locally in your browser. MD5 and SHA-1 are weak for security — prefer SHA-256+ for integrity checks.
In-depth explanation
Generate MD5, SHA-1, SHA-256, SHA-384, and SHA-512 digests from text. Useful for checksums and integrity checks — not for storing passwords. Everything runs locally in your browser — your inputs are not uploaded to produce the result.
Prefer SHA-256 or stronger for integrity. MD5 and SHA-1 are weak for security use cases. This tool hashes text input. Paste file contents as text if needed.
Hashes are computed locally with the Web Crypto API (and a local MD5 implementation). Tweak the inputs above to compare options, then copy or note the result you need.
Hashes are one-way fingerprints. MD5 and SHA-1 are broken for security but still appear in old checksums. Prefer SHA-256 or stronger for integrity. Do not hash passwords here and store them — use a proper password hash (Argon2, bcrypt) in your app.
Same text always produces the same digest. A single character change does not. File hashing would need the file bytes; this hashes the text you paste. Computation is local.
Frequently asked questions
Which algorithm should I use?
Prefer SHA-256 or stronger for integrity. MD5 and SHA-1 are weak for security use cases.
Can I hash files?
This tool hashes text input. Paste file contents as text if needed.
Is my text uploaded?
No. Hashes are computed locally with the Web Crypto API (and a local MD5 implementation).
