Cryptography

One-way functions are the foundation of modern cryptography, which are used by both asymmetric ciphers and hash functions.

For instance, the message encrypted with the public key can not be decrypted with the public key, because the public key encryption is an one-way function. And once a message is hashed, people should not be able to recover the original message from the hash.
