Random password generator. A random password generator is a software program or hardware device that takes input from a random or pseudo-random number generator and automatically generates a password. Random passwords can be generated manually, using simple sources of randomness such as dice or coins, or they can be generated using a computer.
Random password programs often can ensure that the resulting password complies with a local password policy; for instance, by always producing a mix of letters, numbers, and special characters. For passwords generated by a process that randomly selects a string of symbols of length, L, from a set of N possible symbols, the number of possible ...
In cryptography, a salt is random data fed as an additional input to a one-way function that hashes data, a password or passphrase. [1] Salting helps defend against attacks that use precomputed tables (e.g. rainbow tables), by vastly growing the size of table needed for a successful attack. [2][3][4] It also helps protect passwords that occur ...
A key in cryptography is a piece of information, usually a string of numbers or letters that are stored in a file, which, when processed through a cryptographic algorithm, can encode or decode cryptographic data. Based on the used method, the key can be different sizes and varieties, but in all cases, the strength of the encryption relies on ...
Password Safe is a free and open-source password manager program originally written for Microsoft Windows but supporting a wide array of operating systems, with compatible clients available for Linux, FreeBSD, Android, IOS, BlackBerry and other operating systems.
In the asymptotic setting, a family of deterministic polynomial time computable functions : {,} {,} for some polynomial p, is a pseudorandom number generator (PRNG, or PRG in some references), if it stretches the length of its input (() > for any k), and if its output is computationally indistinguishable from true randomness, i.e. for any probabilistic polynomial time algorithm A, which ...
The simplest example of a challenge-response protocol is password authentication, where the challenge is asking for the password and the valid response is the correct password. An adversary who can eavesdrop on a password authentication can authenticate themselves by reusing the intercepted password. One solution is to issue multiple passwords ...
Security token. A GoldKey security token connected to a laptop. A security token is a peripheral device used to gain access to an electronically restricted resource. The token is used in addition to, or in place of, a password. [1] Examples of security tokens include wireless key cards used to open locked doors, a banking token used as a ...
