Secure random string generation
Secure string #
This is a cryptographically secure random string generator based on dart:math.Random.secure
.
Usage: #
Create an instance with new SecureString()
:
SecureString secureString = new SecureString();
Then generate random strings with it:
String randomString = secureString.generate(length: 512);
The length defaults to 1024
if no length is specified.
Custom character lists #
To specify a list of allowed characters, use the named parameter charList
:
String randomBinaryString = secureString.generate(charList: ["0", "1"]);
The list defaults to hexadecimal characters (0-f).
Insecure string: #
To create insecure random strings: use new SecureString(string: false)
instead of new SecureString()
. You can also specify a seed using new SecureString(string: false, seed: 2)
(replacing 2 with your seed).
Trivia: #
This library was made in spite of a library already existing due to two reasons:
- That library did not have functionality for
Random.secure
. - That library was licensed under the BSD 3 clause license.
