securestring

An implementation to securely hold a private string in memory implemented in Scala 2.10.3.

Example

val password = Array[Char]('p', 'a', 's', 's')
val securestring = SecureString(password)

// original array is wiped out
println(password.toSeq) // prints 4 times the char '\0'

// access the secret string
// encrypted string is decrypted and passed to the inner funciton
securestring.read { plain =>
  println(plain.mkString) // prints "pass"
}

// after the inner function the decrypted char array is automatically wiped out
