Reino: Security Features

La seguridad de un software no es un software de seguridad. Nos preocupamos de cuestiones como la autenticación, el control de acceso, la confidencialidad, la criptografía y la gestión de privilegios.

Weak Cryptographic Hash: Predictable Salt

Abstract
Los valores de sal deben crearse con un generador de números pseudoaleatorios criptográfico.
Explanation
Los valores de sal deben crearse con un generador de números pseudoaleatorios criptográfico. Cuando no se utiliza un valor de sal aleatorio, el hash o hmac resultante es mucho más predecible y susceptible a un ataque por diccionario.

Ejemplo 1: el siguiente código reutiliza la contraseña como sal:


...
byte[] passwd = Encoding.UTF8.GetBytes(txtPassword.Text);
Rfc2898DeriveBytes rfc = new Rfc2898DeriveBytes(passwd, passwd,10001);
...

Abstract
Los valores de sal deben crearse con un generador de números pseudoaleatorios criptográfico.
Explanation
Los valores de sal deben crearse con un generador de números pseudoaleatorios criptográfico. Cuando no se utiliza un valor de sal aleatorio, el hash o HMAC resultante es mucho más predecible y susceptible a un ataque por diccionario.

Ejemplo 1: El siguiente código reutiliza la contraseña como sal:


require 'openssl'
...
req = Rack::Response.new
password = req.params['password']
...
key = OpenSSL::PKCS5::pbkdf2_hmac(password, password, 100000, 256, 'SHA256')
...
