Frequently Asked Questions

What is hashing? expand_more

Hashing converts data into a fixed-size string of characters. The same input always produces the same hash, but the process is one-way.

Which algorithm should I use? expand_more

For security, use SHA-256 or SHA-512. MD5 and SHA-1 are faster but considered cryptographically weak for security purposes.

Can hashes be reversed? expand_more

No, cryptographic hashes are one-way functions. You cannot retrieve the original data from a hash.

Is MD5 still useful? expand_more

MD5 is fast but not secure for passwords or cryptographic purposes. However, it's still useful for file checksums and non-security data verification.

What is a salt in hashing? expand_more

A salt is random data added to passwords before hashing to prevent rainbow table attacks. The [Hash Generator](/tools/hash-generator/) doesn't support salting—use backend code for production password hashing.

Can I verify file integrity? expand_more

Yes! Generate a hash of your file with the [Hash Generator](/tools/hash-generator/), then rehash after download. If hashes match, the file hasn't been corrupted.

What is collision probability? expand_more

For MD5 and SHA-1, collisions are possible due to algorithm weaknesses. For SHA-256 and SHA-512, collisions are computationally infeasible—they're effectively impossible.

How do I use hashes for passwords? expand_more

Never store plain text passwords. Hash them with SHA-256 or bcrypt (with salt) before storage. On login, hash the entered password and compare with stored hash.
