Generate Random Sequence (Random field generator
Description
rand
can generate random numbers, strings and other data types.
Usage
rand data-type [ max-value ]
Examples
Specifying data-type
Random integer (64-bit on 64-bit machines):
rand int
Specifying custom range
Random integer between 0 and 9:
rand int 9
Random floating point number between 0 and 1:
rand float
Random string, fixed to 5 characters long:
rand str 5
Flags
*
Alias for str (string)float
Random floating point number between 0 and 1. max-value not supportedint
Random integer, max-value specifies highest value for integernum
Alias for int in this builtinstr
Random string of printable ASCII characters. max-value specifies the fixed length of the string
Detail
Security
WARNING: is should be noted that while rand
can produce random numbers and strings which might be useful for password generation, neither the RNG nor the the random string generator (which is ostensibly the same RNG but applied to an array of bytes within the range of printable ASCII characters) are considered cryptographically secure.
