Hash Generator Online – Free MD5, SHA1, SHA256 Hash Generator

Yes! Our hash generator processes all hashing entirely in your browser. Your sensitive passwords, data, and text never leave your device, ensuring complete privacy and security. We don't store, transmit, or have access to any of your data.

MD5 produces a 128-bit hash (32 hex characters) and is fast but cryptographically broken - not recommended for security. SHA-256 produces a 256-bit hash (64 hex characters) and is currently the most widely used secure algorithm. SHA-512 produces a 512-bit hash (128 hex characters) and offers the highest security level.

While our hash generator can generate password hashes, for production applications you should use key stretching techniques like PBKDF2, bcrypt, or Argon2 in addition to hashing. Our tool is perfect for testing, development, and learning hash algorithms.

For password hashing, use SHA-256 or SHA-512 combined with salt and key stretching. For data integrity verification, SHA-256 is recommended. For high-security applications, use SHA-384 or SHA-512. For non-security checksums, MD5 is acceptable.

Currently, our hash generator supports text input. You can paste any text string including file contents and generate its hash. For file hashing, read the file content as text first, then paste it into the generator.

Yes! Our hash generator is completely free with no registration required, no hidden costs, and no usage limits. You can generate unlimited hashes and use all algorithms without restrictions.

No, hash functions are one-way cryptographic functions. You cannot reverse a hash to get the original input. This is by design for security purposes. However, attackers can use rainbow tables or brute force for common passwords.

Yes! Once the page is loaded, our hash generator works completely offline. You can generate hashes, copy results, and download files without an internet connection. All processing happens in your browser.
