zend-math 3.0.0

This version contains a number of changes to required dependencies, error handling, and internals; please read the migration document for full details.

Added

• #18 adds a requirement on ext/mbstring.
• #18 adds a requirement on paragonie/random_compat for polyfilling PHP 7's random_bytes() and random_int() functionality.
• #20 prepares and publishes documentation to https://zendframework.github.io/zend-math/

Deprecated

• Nothing.

Removed

• #18 removes the
  $strong optional parameter from the following methods, as the component now
  ensures a cryptographically secure pseudo-random number generator is always
  used:
  • Rand::getBytes($length)
  • Rand::getBoolean()
  • Rand::getInteger($min, $max)
  • Rand::getFloat()
  • Rand::getString($length, $charlist = null)
• #18 removes the
  requirement on ircmaxell/random-lib, in favor of paragonie/random_compat (as
  noted above); this also resulted in the removal of:
  • direct usage of mcrypt (this is delegated to paragonie/random_compat)
  • direct usage of /dev/urandom or COM (this is delegated to
    random_bytes() and/or paragonie/random_compat)
  • Zend\Math\Source\HashTiming, as it was used only with RandomLib.

Fixed

• #18 updates the code to
  replace usage of substr() and strlen() with mb_substr() and
  mb_strlen(); these ensure that all string manipulations within the component
  remain binary safe.
