cryptiles=========General purpose crypto utilities[](http://travis-ci.org/hapijs/cryptiles)Lead Maintainer - [C J Silverio](https://github.com/ceejbot)## Methods### `randomString(<Number> size)`Returns a cryptographically strong pseudo-random data string. Takes a size argument for the length of the string.### `randomDigits(<Number> size)`Returns a cryptographically strong pseudo-random data string consisting of only numerical digits (0-9). Takes a size argument for the length of the string.### `fixedTimeComparison(<String> a, <String> b)`Compare two strings using fixed time algorithm (to prevent time-based analysis of MAC digest match). Returns `true` if the strings match, `false` if they differ.
