Hash Comparison
What is a Hash Function?
A cryptographic hash function converts input data of any size into a fixed-size string of characters. The output (hash) is deterministic, meaning the same input always produces the same hash.
Hash Algorithm Comparison:
| Algorithm | Output Size | Security | Use Case |
|---|---|---|---|
| MD5 | 128-bit (32 chars) | Broken | Checksums only |
| SHA-1 | 160-bit (40 chars) | Deprecated | Legacy systems |
| SHA-256 | 256-bit (64 chars) | Secure | Recommended |
| SHA-512 | 512-bit (128 chars) | Secure | High security |
Frequently Asked Questions
No. Hash functions are designed to be one-way. You cannot mathematically reverse a hash. However, weak passwords can be cracked using rainbow tables or brute force, which is why you should use strong, unique passwords.
Absolutely not! MD5 is cryptographically broken. For passwords, use specialized password hashing algorithms like bcrypt, Argon2, or PBKDF2 that include salting and are designed to be slow.
A collision occurs when two different inputs produce the same hash output. While theoretically possible for all hash functions, secure algorithms like SHA-256 make finding collisions computationally infeasible.
