SecureRandom (secure_random_ex v0.6.0)
Summary
Functions
Returns random Base64 encoded string.
Generates a random hexadecimal string.
Returns random bytes.
Returns random urlsafe Base64 encoded string.
Returns UUID v4 string. I have lifted most of this straight from Ecto's implementation.
Functions
base64(n \\ 16)
Returns random Base64 encoded string.
Examples
iex> SecureRandom.base64
"rm/JfqH8Y+Jd7m5SHTHJoA=="
iex> SecureRandom.base64(8)
"2yDtUyQ5Xws="
hex(n \\ 16)
Generates a random hexadecimal string.
The argument n specifies the length, in bytes, of the random number to be generated. The length of the resulting hexadecimal string is twice n.
If n is not specified, 16 is assumed. It may be larger in future.
The result may contain 0-9 and a-f.
Examples
iex> SecureRandom.hex(6)
"34fb5655a231"
random_bytes(n \\ 16)
Returns random bytes.
Examples
iex> SecureRandom.random_bytes
<<202, 104, 227, 197, 25, 7, 132, 73, 92, 186, 242, 13, 170, 115, 135, 7>>
iex> SecureRandom.random_bytes(8)
<<231, 123, 252, 174, 156, 112, 15, 29>>
urlsafe_base64(n \\ 16)
Returns random urlsafe Base64 encoded string.
Examples
iex> SecureRandom.urlsafe_base64
"xYQcVfWuq6THMY_ZVmG0mA"
iex> SecureRandom.urlsafe_base64(8)
"8cN__l-6wNw"
uuid()
Returns UUID v4 string. I have lifted most of this straight from Ecto's implementation.
Examples
iex> SecureRandom.uuid "e1d87f6e-fbd5-6801-9528-a1d568c1fd02"
