PHP has a direct module interface called SAPI for different web servers; [272] in case of PHP 5 and Apache 2.0 on Windows, it is provided in form of a DLL file called php5apache2.dll, [273] which is a module that, among other functions, provides an interface between PHP and the web server, implemented in a form that the server understands. This ...
Through the collaboration of several OATH members, a TOTP draft was developed in order to create an industry-backed standard. It complements the event-based one-time standard HOTP, and it offers end user organizations and enterprises more choice in selecting technologies that best fit their application requirements and security guidelines.
Code can be modularized into functions defined with keyword function. PHP supports an optional object oriented coding style, with classes denoted by the class keyword. Functions defined inside classes are sometimes called methods. Control structures include: if, while, do/while, for, foreach, and switch. Statements are terminated by a semicolon ...
A more complex example is the lexer hack in C, where the token class of a sequence of characters cannot be determined until the semantic analysis phase since typedef names and variable names are lexically identical but constitute different token classes. Thus in the hack, the lexer calls the semantic analyzer (say, symbol table) and checks if ...
In computing, a personal access token (or PAT) is a string of characters that can be used to authenticate a user when accessing a computer system instead of the usual password.
Token Generation is the process of producing a token using any means, such as mathematically reversible cryptographic functions based on strong encryption algorithms and key management mechanisms, one-way nonreversible cryptographic functions (e.g., a hash function with strong, secret salt), or assignment via a randomly generated number.
where ":" is used to extract bits from a starting bit number up to and including an ending bit number, where these bit numbers are 0-origin. The use of "19" in the above formula relates to the size of the output from the hash function. With the default of SHA-1, the output is 20 bytes, and so the last byte is byte 19 (0-origin).
One popular system, used in Hashcash, uses partial hash inversions to prove that computation was done, as a goodwill token to send an e-mail. For instance, the following header represents about 2 52 hash computations to send a message to calvin@comics.net on January 19, 2038: X-Hashcash: 1:52:380119:calvin@comics.net:::9B760005E92F0DAE
