Algorithm Performance Comparison

MD5 (ops/sec)

SHA-256 (ops/sec)

bcrypt (ops/sec)

Argon2 (ops/sec)

Higher numbers indicate faster hashing (less secure for passwords). bcrypt and Argon2 are designed to be slow.

Understanding Hash Functions

What are Hash Functions?

Hash functions are cryptographic algorithms that take input data of any size and produce a fixed-size string of characters. They are:

Deterministic: Same input always produces same output
One-way: Cannot reverse-engineer input from output
Collision-resistant: Difficult to find two inputs with same output

Common Use Cases

Password Storage

Store hashes instead of plain passwords (use bcrypt/Argon2)

Data Integrity

Verify files haven't been modified during transfer

Digital Signatures

Create unique fingerprints for data verification

Hash Algorithm Security Guide

Algorithm	Security Level	Use For	Notes
MD5	Broken	Checksums only	Vulnerable to collisions, not for security
SHA-1	Weak	Legacy systems	Theoretical collisions possible
SHA-256	Strong	Data integrity, certificates	Current standard for general use
bcrypt	Strong	Password storage	Adaptive, slow by design
Argon2	Very Strong	Password storage	Memory-hard, 2015 winner
