Crypt class Null safety
One-way string hashing for salted passwords using the Unix crypt format.
This class implements SHA-256 and SHA-512 crypt hashes as specified by "Unix crypt using SHA-256 and SHA-512" (version: 0.6 2016-08-31).
Usage
Construct a Crypt object using the Crypt.sha256 or Crypt.sha512 constructors, or by parsing a crypt formatted string with the default Crypt constructor.
The crypt format string value is obtained from a Crypt object by using its toString method.
To test if a value matches a Crypt hash, create a Crypt object from the crypt format string and then invoke the match method with the value being tested.
The value of cryptographicallySecureSalts controls if the use of non-cryptographically secure random number generators are allowed to be used on platforms that do not have a cryptographically secure random number generator. A random number generator is needed if random salts are needed to be generated.
Note: The hashCode method has nothing to do with the crypt hashes. It is a standard method in all Dart objects.
