Implements: IEquatable<HashAlgorithmName>

Remarks

TheHashAlgorithmName structure includes some static properties that return predefined hash algorithm names, as well as aName property that can represent a custom hash algorithm name as a strongly-typed string. Hash algorithm names are case-sensitive.

Asymmetric algorithms implemented using Microsoft's CNG (Cryptographic Next Generation) API interpret the underlying string value as aCNG algorithm identifier.

Asymmetric algorithms implemented using other technologies:

Must recognize at least "MD5", "SHA1", "SHA256", "SHA384", and "SHA512".
Should recognize additional CNG identifiers for any additional hash algorithms that they support.

Due to collision problems with MD5 and SHA-1, Microsoft recommends a security model based on SHA-256 or better.

Constructors

Name	Description
HashAlgorithmName(String)	Initializes a new instance of theHashAlgorithmName structure with a custom name.

Properties

Name	Description
