@@ -5,7 +5,7 @@ Format preserving encryption (FPE) refers to a set of techniques for
 encrypting data such that the ciphertext has the same format as the
 plaintext. For instance, you can use FPE to encrypt credit card
 numbers with valid checksums such that the ciphertext is also an

 account numbers, US Social Security numbers, or even more general
