Public key cryptography algorithms solve the key distribution problem by using two mathematically linked keys, eliminating the need to share secrets over insecure channels.
Hashing creates a unique digital fingerprint for data, ensuring that even a single bit change produces a completely different output value for verification.
Hashing transforms variable data into a fixed fingerprint that changes completely if even one bit of the original input is altered.
