Result: Same input, three different outputs with different properties.
Hashing vs Encryption vs Encoding Demo
EDUCATIONAL DEMONSTRATION ONLY. Three commonly confused concepts: Hashing (one-way fingerprint), Encoding (format conversion, always reversible), and Encryption (reversible transformation with a key). This demo processes the same input through all three to show the differences.

Frequently asked questions
Can Base64 decoded data be called encrypted?
No. Base64 is encoding, not encryption. Anyone can decode it without a key. Encoding provides zero confidentiality.
When should I use hashing vs encryption?
Hash when you need to verify data (passwords, file integrity) and never need to recover the original. Encrypt when you need to protect confidentiality and must recover the plaintext later.
Is MD5 hashing or encryption?
MD5 is a hash function. It is one-way - you cannot reverse a hash to get the original input. Encryption is always reversible with the correct key.
