2. Format-preserving encryption - Wikipedia

   en.wikipedia.org/wiki/Format-preserving_encryption

   In cryptography, format-preserving encryption (FPE), refers to encrypting in such a way that the output (the ciphertext) is in the same format as the input (the plaintext). The meaning of "format" varies. Typically only finite sets of characters are used; numeric, alphabetic or alphanumeric. For example:

3. Format-transforming encryption - Wikipedia

   en.wikipedia.org/wiki/Format-transforming_encryption

   Similar to format-preserving encryption, FTE can be used to control the format of ciphertexts. The canonical example is a credit card number, such as 1234567812345670 (16 bytes long, digits only). However, FTE does not enforce that the input format must be the same as the output format.

4. PeaZip - Wikipedia

   en.wikipedia.org/wiki/PeaZip

   PeaZip supports encryption [21] with AES 256-bit cipher in 7z and ZIP archive formats. In PeaZip's native PEA format, and in FreeArc's ARC format, supported ciphers are AES 256-bit, Blowfish, [22] Twofish [23] 256 and Serpent 256 (in PEA format, all ciphers are used in EAX authenticated encryption mode).

   The example is suggesting, that it is ok to encrypt credit card numbers with format-preserving encryption. In reality, storing them should be avoided completely if possible, otherwise one have to follow the PCI standard. I recommend to look for another example, maybe for obfuscating row ids in an url.

6. Block cipher - Wikipedia

   en.wikipedia.org/wiki/Block_cipher

   In some situations, however, one may wish to have a block cipher that works over some other alphabet; for example, encrypting 16-digit credit card numbers in such a way that the ciphertext is also a 16-digit number might facilitate adding an encryption layer to legacy software. This is an example of format-preserving encryption.

7. Privacy-enhancing technologies - Wikipedia

   en.wikipedia.org/wiki/Privacy-enhancing_technologies

   Format-preserving encryption (FPE), refers to encrypting in such a way that the output (the ciphertext) is in the same format as the input (the plaintext) Blinding is a cryptography technique by which an agent can provide a service to a client in an encoded form without knowing either the real input or the real output.

   Encryption scrambles and unscrambles your data to keep it protected. • A public key scrambles the data. • A private key unscrambles the data. Credit card security. When you make a purchase on AOL, we'll only finish the transaction if your browser supports SSL.
