About Hash Functions
Hash functions convert input data into fixed-length strings. They are one-way functions - you cannot reverse them to get the original input.
MD5 (128-bit)
Fast but cryptographically broken. Use only for checksums, not security.
SHA-256 (256-bit)
Secure and widely used. Part of the SHA-2 family. Good for most applications.
SHA-512 (512-bit)
Most secure option. Longer hash provides higher security but uses more space.
