This gem is a backport of the built-in securerandom method from Ruby 1.8.7.

This library is an interface for secure random number generator which is suitable for generating session key in HTTP cookies, etc.

It supports following secure random number generators.

* openssl
* /dev/urandom

Examples

SecureRandom.hex(10) => "52750b30ffbc7de3b362"
SecureRandom.hex(10) => "92b15d6c8dc4beb5f559"
SecureRandom.hex(11) => "6aca1b5c58e4863e6b81b8"
SecureRandom.hex(12) => "94b2fff3e7fd9b9c391a2306"
SecureRandom.hex(13) => "39b290146bea6ce975c37cfc23"

Examples

SecureRandom.base64(10) => "EcmTPZwWRAozdA=="
SecureRandom.base64(10) => "9b0nsevdwNuM/w=="
SecureRandom.base64(10) => "KO1nIU+p9DKxGg=="
SecureRandom.base64(11) => "l7XEiFja+8EKEtY="
SecureRandom.base64(12) => "7kJSM/MzBJI+75j8"
SecureRandom.base64(13) => "vKLJ0tXBHqQOuIcSIg=="

Examples

SecureRandom.random_bytes(10) => "\016\t{\370g\310pbr\301"
SecureRandom.random_bytes(10) => "\323U\030TO\234\357\020\a\337"
