module SecureRandom
Secure random number generator interface.¶ ↑
This library is an interface to secure random number generators which are suitable for generating session keys in HTTP cookies, etc.
You can use this library in your application by requiring it:
require 'securerandom'
It supports the following secure random number generators:
-
openssl
-
/dev/urandom
SecureRandom
is extended by the Random::Formatter
module which defines the following methods:
-
alphanumeric
-
base64
-
choose
-
gen_random
-
hex
-
rand
-
random_bytes
-
random_number
-
urlsafe_base64

.
If a secure random number generator is not available, NotImplementedError
is raised.
