Understanding Encryption

Types of Encryption

Symmetric Encryption

Uses the same key for encryption and decryption. Fast and efficient for large data. Examples: AES, DES, Blowfish.

Base64 Encoding

Not encryption - just encoding binary data as ASCII text. Useful for data transfer. Easily reversible without a key.

Hashing

One-way function that produces fixed-size output. Cannot be reversed. Used for passwords, checksums, integrity verification.

When to Use Each

Encryption: Protecting sensitive data that needs to be retrieved later
Base64: Encoding binary data for transmission (images in URLs, email attachments)
Hashing: Password storage, file integrity checks, digital signatures
