Frequently Asked Questions
What is a hash function?
A hash function converts input data into a fixed-size string of characters, typically represented in hexadecimal. Different inputs produce different hashes, and the process is one-way (cannot be reversed).
What is the difference between MD5, SHA-1, SHA-256?
MD5 (128-bit) is fast but insecure. SHA-1 (160-bit) is also broken. SHA-256 (256-bit) is secure and recommended. Larger hash sizes = more security.
When should I use hashing?
Hashing is used for password storage, file verification, checksums, and data integrity checks. Never use MD5 or SHA-1 for passwords; use bcrypt or argon2.
Can I reverse a hash?
No, cryptographic hashing is one-way. You cannot recover the original input from a hash. This is by design.
