Question

Quizplus · Accepted Answer

Format-preserving encryption (FPE) is designed to encrypt data in such a way that the output (the ciphertext) is in the same format as the input (the plaintext). This is particularly useful in applications where the format of the data must be maintained, such as encrypting credit card numbers, where the ciphertext must still look like a credit card number.
