System.Security.Policy.StrongName Class

Summary

Provides the strong name of a code assembly as evidence for policy evaluation. This class cannot be inherited.

C# Syntax:

[Serializable] public sealed class StrongName : IIdentityPermissionFactory

The StrongName class represents evidence of a unique, cryptographically strong name of a code assembly. The strong name consists of a public key, a given name, and a version. The public key corresponds to the publisher's private key which is kept secret, and with which the assembly must be signed in order for the strong name to be valid.

Strong names are typically assigned to assemblies using either AssemblyKeyFileAttribute, System.Reflection.AssemblyKeyNameAttribute (not supported on the shared source CLI) or AssemblyDelaySignAttribute in conjunction with the SN utility (see ).

StrongNameIdentityPermission uses this class to confirm that calling code is in a particular strong-named code assembly.

System.Security.Policy.StrongName Member Details

Summary

Initializes a new instance of the StrongName class with the strong name public key blob, name, and version.

C# Syntax:

public StrongName(StrongName(    StrongNamePublicKeyBlob blob,    string name,    Version version );

blob

The StrongNamePublicKeyBlob of the software publisher.

name

The simple name section of the strong name.

version

The Version of the strong name.

Exceptions

Exception Type	Condition
ArgumentNullException	The blob parameter is null. -or- The name parameter is null. -or- The version parameter is null.

Summary

Gets the simple name of the current StrongName.

C# Syntax:

public string Name {get;}

Return to top

Summary

Gets the StrongNamePublicKeyBlob of the current StrongName.

C# Syntax:

public StrongNamePublicKeyBlob PublicKey {get;}

A blob is cryptographic information that uniquely specifies the public key of the software publisher.

Blobs differ from certificates in that the blob only has information about the public key; the certificate also includes information that associates the name of the holder with the key as well as information to verify the certificate.

Summary

Gets the Version of the current StrongName.

C# Syntax:

public Version Version {get;}

Return to top

Summary

Creates an equivalent copy of the current StrongName.

C# Syntax:

public object Copy();

Return Value:

A new, identical copy of the current StrongName.

Return to top

Summary

Creates a StrongNameIdentityPermission that corresponds to the current StrongName.

C# Syntax:

public IPermission CreateIdentityPermission(    Evidence evidence );

evidence

The Evidence from which to construct the StrongNameIdentityPermission.

Return Value:

A StrongNameIdentityPermission for the specified StrongName.

Implements:

IIdentityPermissionFactory.CreateIdentityPermission

The identity permission for a strong name can be used to determine whether calling code is in a particular strong named code assembly.

Return to top

Summary

Determines whether the specified strong name is equal to the current strong name.

C# Syntax:

public override bool Equals(    object o );

o

The strong name to compare against the current strong name.

Return Value:

true if the specified strong name is equal to the current strong name; otherwise, false.

Summary

Gets the hash code of the current StrongName.

C# Syntax:

public override int GetHashCode();

Return Value:

The hash code of the current StrongName.

Summary

Creates a string representation of the current StrongName.

C# Syntax:

public override string ToString();

Return Value:

A representation of the current StrongName.

This method is useful during debugging to get an easy-to-read representation of the object.
