Frequently Asked Questions

What is a hash function? ▼

A hash function converts input data into a fixed-size string of characters, which is nearly impossible to reverse. Common algorithms include MD5, SHA-1, SHA-256, and SHA-512.

Is MD5 still secure? ▼

MD5 is considered cryptographically broken and should not be used for further use. Use SHA-256 or SHA-512 for secure applications.

Can I decrypt a hash? ▼

No, hashes are one-way functions. You cannot decrypt a hash back to the original input. This is by design for security.
