Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
Provides a Cryptography Next Generation (CNG) implementation of the Secure Hash Algorithm (SHA).
public ref class SHA1Cng sealed : System::Security::Cryptography::SHA1
public sealed class SHA1Cng : System.Security.Cryptography.SHA1
type SHA1Cng = class
inherit SHA1
Public NotInheritable Class SHA1Cng
Inherits SHA1
- Inheritance
Remarks
This algorithm is for hashing only and does not provide any encryption or decryption.
Due to collision problems with SHA1, Microsoft recommends SHA256.
