👉 In the field of computer science, a "posterization" is a technique that involves encrypting data using a cryptographic hash function and then converting it back to its original form. This process allows for the storage and retrieval of encrypted data without any loss of information. For example, consider an encryption algorithm such as AES (Advanced Encryption Standard). When you use this algorithm to encrypt a message, the algorithm first generates a hash of the message, which is a unique value that can be used to verify the
