require 'securerandom' SecureRandom.hex(10) #=> "52750b30ffbc7de3b362" SecureRandom.hex(10) #=> "92b15d6c8dc4beb5f559" SecureRandom.hex(13) #=> "39b290146bea6ce975c37cfc23"
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"
