About Hash Functions

Hash functions convert input data into a fixed-size string of characters. They're one-way functions — you can't reverse a hash to get the original input.

Which Hash Should I Use?

MD5 - Fast but not secure. Only for checksums, never for security.
SHA-1 - Deprecated for security. Still used in Git.
SHA-256 - ⭐ Recommended for most uses. Secure and widely supported.
SHA-512 - More secure, longer output. Good for high-security needs.
