**Random number generation**is a process by which, often by means of a**random**number**generator**(RNG), a sequence of numbers or symbols that cannot be reasonably predicted better than by**random**chance is generated. This means that the particular outcome sequence will contain some patterns detectable in hindsight but unpredictable to foresight.Common PRNG (pseudorandom number

**generator**) — preferably cryptographically secure — in both transmitter and receiver; Transmitter sends 'next' code in sequence; Receiver compares 'next' to its calculated 'next' code. A typical implementation compares within the next 256 codes in case receiver missed some transmitted keypresses.Key size is the number of bits in the key defined by the algorithm. This size defines the upper bound of the cryptographic algorithm’s security. The larger the key size, the longer it will take before the key is compromised by a brute force attack.

**Backtracking**is a class of algorithm for finding solutions to some computational problems, notably constraint satisfaction problems, that incrementally builds candidates to the solutions, and abandons a candidate ("backtracks") as soon as it determines that the candidate cannot possibly be completed to a valid solution.This implies

**random**key choice to force attackers to spend as much effort as possible; this is very difficult in principle and in practice as well. As a general rule, any software except a cryptographically secure pseudorandom number**generator**(CSPRNG) should be avoided. See also.

**random**value. The**bcrypt**function uses these inputs to compute a 24-byte (192-bit) hash. The final output of the**bcrypt**function is a string of the form: $2<a/b/x/y>$[cost]$[22 character salt][31 character hash] For example, with input**password**abc123xyz, cost 12, and a**random**salt, the output of**bcrypt**is the string
