About this video
π Cipher Text
Definition: Encrypted form of plain text produced using an encryption algorithm + key.
Purpose: Keeps the message secret β only someone with the correct decryption key can turn it back into plain text.
Example:
Plain Text: HELLO
After encryption (Caesar Cipher shift 3): KHOOR
π Cipher text is reversible (can be decrypted back).
---
π Hash
Definition: A fixed-length string generated from input data using a hashing algorithm (e.g., MD5, SHA-256).
Purpose: Ensures data integrity β if even one character changes, the hash output is completely different.
Example:
Input: HELLO
SHA-256 Hash: 185f8db32271fe25f561a6fc938b2e264306ec304eda518007d1764826381969
π Hash is one-way (cannot be reversed).

β Difference in one line:
Cipher Text = Encrypted data (reversible with key).
Hash = Data fingerprint (irreversible).
