Question 1

What is the difference between MD5, SHA-256, and SHA-512 hash algorithms?

Accepted Answer

Each algorithm offers different security levels and hash lengths:        • **MD5 (128-bit):** Fast but cryptographically broken. Only use for non-security applications like file checksums.        • **SHA-256 (256-bit):** Highly secure and widely recommended. Perfect for password hashing, blockchain, and certificates.        • **SHA-512 (512-bit):** Maximum security with longer hash length. Ideal for high-security applications and critical systems.        For most applications, SHA-256 provides the best balance of security and performance.

Question 2

Why should I use salt when generating password hashes?

Accepted Answer

Salt is crucial for password security because it:        • **Prevents rainbow table attacks:** Pre-computed hash tables become useless with unique salts         • **Ensures unique hashes:** Same passwords produce different hashes with different salts         • **Increases complexity:** Makes brute force attacks significantly more difficult         • **Industry standard:** Required by security frameworks like OWASP and NIST          Always use a unique, random salt for each password. Our tool can generate secure random salts automatically.

Question 3

How many iterations should I use for password hashing?

Accepted Answer

The number of iterations depends on your security requirements and performance needs:        • **1 iteration:** Basic hashing for checksums and non-security applications         • **1,000-10,000 iterations:** Good for password hashing with moderate security         • **100,000+ iterations:** Recommended by OWASP for high-security applications          More iterations = better security but slower processing. Find the right balance for your use case. Our tool supports up to 10,000 iterations for testing purposes.

Question 4

Is this hash generator secure and private?

Accepted Answer

Yes, our hash generator prioritizes security and privacy:        • **Client-side processing:** Hashing happens in your browser when possible         • **No data storage:** We don't store your input text or generated hashes         • **HTTPS encryption:** All communication is encrypted in transit         • **Open source algorithms:** Uses standard Node.js crypto library implementations         • **No tracking:** We don't log or monitor your hash generation activities          For maximum security with sensitive data, consider running the tool locally or using offline hash generators.

Question 5

Can I use this tool for commercial or enterprise applications?

Accepted Answer

Yes, our hash generator is free for both personal and commercial use:        • **No usage limits:** Generate as many hashes as needed         • **Commercial friendly:** Use in your applications and services         • **API access:** Integrate with your systems (rate limits may apply)         • **Enterprise features:** Batch processing and advanced options available          For high-volume commercial use, consider implementing your own hash generation system using standard cryptographic libraries.

Question 6

How do I verify file integrity using hash checksums?

Accepted Answer

To verify file integrity:        1. **Generate hash:** Create a hash of the original file       2. **Store hash:** Save the hash value securely       3. **Transfer file:** Send or download the file       4. **Re-hash:** Generate a new hash from the received file       5. **Compare:** If both hashes match, the file is intact        This is commonly used for software downloads, backup verification, and ensuring data hasn't been corrupted during transmission.
