Generate random base64 strings:

SecureRandom.base64(10)#=> "EcmTPZwWRAozdA=="SecureRandom.base64(10)#=> "KO1nIU+p9DKxGg=="SecureRandom.base64(12)#=> "7kJSM/MzBJI+75j8"

Generate random binary strings:

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

Generate alphanumeric strings:

SecureRandom.alphanumeric(10)#=> "S8baxMJnPl"SecureRandom.alphanumeric(10)#=> "aOxAg8BAJe"

Generate UUIDs:

SecureRandom.uuid#=> "2d931510-d99f-494a-8c67-87feb05e1594"SecureRandom.uuid#=> "bad85eb9-0713-4da7-8d36-07a8e4b00eab"
