What is Base64, URL Encode, MD5 and SHA256?

What is Base64?

Base64 converts binary data to ASCII text — used in email attachments, HTML images, and JWT tokens.

What is URL Encode?

Converts special characters in URLs, e.g. space → %20, ? → %3F to make URLs valid.

MD5 and SHA256

Hash functions that convert data into a fixed-length fingerprint, used to verify file integrity.

MD5 should not be used for passwords anymore as it can be cracked.
