Point-to-point encryption (P2PE) is a standard established by the PCI Security Standards Council.The objective of P2PE is to provide a payment security solution that instantaneously converts confidential payment card (credit and debit card) data and information into indecipherable code at the time the card is swiped, in order to prevent hacking and fraud.
The PCI Council recommends independent vetting and validation of any claims of security and compliance: "Merchants considering the use of tokenization should perform a thorough evaluation and risk analysis to identify and document the unique characteristics of their particular implementation, including all interactions with payment card data ...
The Payment Card Industry Data Security Standard (PCI DSS) is an information security standard used to handle credit cards from major card brands.The standard is administered by the Payment Card Industry Security Standards Council, and its use is mandated by the card brands.
This class of status code indicates the client must take additional action to complete the request. Many of these status codes are used in URL redirection. [2]A user agent may carry out the additional action with no user interaction only if the method used in the second request is GET or HEAD.
Encryption is often the most complex approach to solving the data masking problem. The encryption algorithm often requires that a "key" be applied to view the data based on user rights. This often sounds like the best solution, but in practice the key may then be given out to personnel without the proper rights to view the data.

[1]: §7.2 The SIP response codes are consistent with the HTTP response codes, although not all HTTP response codes are valid in SIP. [1]: §21 SIP responses also specify a "reason phrase", and a default reason phrase is defined with each response code.
Section 8 of the FIPS 74, Federal Information Processing Standards Publication 1981 Guidelines for Implementing and Using the NBS Data Encryption Standard, [9] describes a way to use the DES encryption algorithm in a manner that preserves the format of the data via modulo-n addition followed by an unbiasing operation. This standard was ...
