This membership condition class uses the value of
Hash evidence to determine if an assembly or
application domain qualifies for membership of a
CodeGroup. The HashValue
property contains the hash value required for membership, and the
HashAlgorithm property contains a
System.Security.Cryptography.HashAlgorithm object
that implements the hash algorithm used to calculate the hash value.
When policy resolution calls the Check( ) method,
if the provided Evidence collection contains a
Hash object, the
HashMembershipCondition object calls the
Hash.GenerateHash( ) method and passes the
System.Security.Cryptography.HashAlgorithm object
from its HashAlgorithm property. If the returned
hash value matches its HashValue property, then
CodeGroup membership is granted.
