SHA-256 Hash Generator Online - SHA-1/256/384/512, Free
1 min read
Hashing turns any text into a fixed-length fingerprint - useful for checksums, dedupe keys, and integrity checks. The hash generator computes SHA-1, SHA-256, SHA-384, and SHA-512 instantly using your browser's built-in Web Crypto.
Quick answer
Open the hash tool, pick an algorithm (default SHA-256), type your text, copy the hex digest.
Step-by-step
- Go to getconvertify.me/tools/hash.
- Choose SHA-1, SHA-256, SHA-384, or SHA-512.
- Paste your input - the digest updates as you type.
- Copy or Download the result.
What you'd use it for
- Checksums - confirm a downloaded file matches its published SHA-256.
- Dedupe keys - stable IDs from content without storing the content.
- Caching - version assets by the hash of their contents.
- Password verification - compare hashes without revealing plaintext (for real auth, use a password-specific algorithm like bcrypt/Argon2, not SHA).
Why SHA-2 over MD5/SHA-1
- MD5 is cryptographically broken and not supported here - don't use it for anything security-sensitive.
- SHA-1 is deprecated; kept for legacy checksum verification.
- SHA-256/512 are the current standard - used by HTTPS certificates, git, and most tools.
Private, in-browser
Hashing runs via the Web Crypto API on your device. Input never leaves the tab - paste secrets and tokens freely.
Common questions
Is a hash encryption? No - hashing is one-way. You can't "decrypt" a hash.
Will the same text always give the same hash? Yes, that's the point - SHA-256("hello") is the same everywhere.
