SecureRandom
Takes my favorite hits from Ruby’s SecureRandom and brings em to elixir. Mostly a convienance wrapper around Erlangs Crypo library, converting Crypto.strong_rand_bytes/1 into a string.
Examples
iex> SecureRandom.base64
"xhTcitKZI8YiLGzUNLD+HQ=="
iex> SecureRandom.urlsafe_base64(4)
"pLSVJw"
iex> SecureRandom.uuid
"a18e8302-c417-076d-196a-71dfbd5b1e03"Summary↑
| base64(n \\ 16) | Returns random Base64 encoded string |
| random_bytes(n \\ 16) | Returns random bytes |
| urlsafe_base64(n \\ 16) | Returns random urlsafe Base64 encoded string |
| uuid() | Returns UUID v4 string |
Functions
