Random passwords can be generated manually, using simple sources of randomness such as dice or coins, or they can be generated using a computer. While there are many examples of "random" password generator programs available on the Internet, generating randomness can be tricky, and many programs do not generate random characters in a way that ...
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 ...
1 Control-C has typically been used as a "break" or "interrupt" key. 2 Control-D has been used to signal "end of file" for text typed in at the terminal on Unix / Linux systems. Windows, DOS, and older minicomputers used Control-Z for this purpose. 3 Control-G is an artifact of the days when teletypes were in use.
Salt (cryptography) 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.
In cryptography, a brute-force attack consists of an attacker submitting many passwords or passphrases with the hope of eventually guessing correctly. The attacker systematically checks all possible passwords and passphrases until the correct one is found. Alternatively, the attacker can attempt to guess the key which is typically created from ...

e. Hypertext Transfer Protocol Secure ( HTTPS) is an extension of the Hypertext Transfer Protocol (HTTP). It uses encryption for secure communication over a computer network, and is widely used on the Internet. [1] [2] In HTTPS, the communication protocol is encrypted using Transport Layer Security (TLS) or, formerly, Secure Sockets Layer (SSL).
The paragraph about the problems with the C standard library random number generator is irrelevant. For generation of an ASCII password, as long as the possible range of outputs is larger than the number of acceptable ASCII characters - from decimal 33 to decimal 126 - the absolute size of the output is unimportant.
