Hash Generator

How it works

1. Enter text. 2. Click Generate Hash. 3. Copy the desired hash.

When to use it

The hash generator is essential for:

• File integrity verification: compare a downloaded file's hash with the distributor's to verify it hasn't been altered.
• Password security: generate hashes to check if passwords have been compromised in data breaches.
• Software development: generate hashes for checksums, digital signatures and data validation in applications.
• Blockchain: understand how cryptographic hashes work as the foundation of cryptocurrencies.
• Digital forensics: calculate hashes of digital evidence to ensure chain of custody.

Advantages

5 hashing algorithms. Instant results. No data stored.

Benefits vs alternatives

Why choose our generator:

• 5 algorithms: MD5, SHA-1, SHA-256, SHA-384, SHA-512 available simultaneously.
• Multiple results: all hashes are generated simultaneously with a single click.
• Total privacy: calculation happens in the browser, text is never sent to our servers.
• Quick copy: copy each individual hash with a dedicated click.
• No limits: calculate hashes of texts of any length without restrictions.

Common mistakes to avoid

1. Using MD5 for security: MD5 is vulnerable to collision attacks and is considered insecure for cryptography. Use SHA-256 or higher for security purposes.
2. Hashing passwords: SHA-256 alone is not suitable for password hashing. Use specific algorithms like bcrypt, scrypt or Argon2 that include salt and are intentionally slow.
3. Comparing hashes from different encodings: the same text in UTF-8 and ISO-8859-1 produces different hashes. Ensure the encoding is the same.
4. Confusing hash and encryption: a hash is irreversible by design. You cannot "decrypt" a SHA-256 hash to recover the original text.
