X509SubjectKeyIdentifierHashAlgorithm Enumeration

Defines the type of hash algorithm to use with the X509SubjectKeyIdentifierExtension class.

Namespace:  System.Security.Cryptography.X509Certificates
Assembly:  System (in System.dll)
public enum X509SubjectKeyIdentifierHashAlgorithm
Member nameDescription
CapiSha1The subject key identifier (SKI) is composed of a 160-bit SHA-1 hash of the encoded public key (including the tag, length, and number of unused bits).
Sha1The SKI is composed of the 160-bit SHA-1 hash of the value of the public key (excluding the tag, length, and number of unused bits).
ShortSha1The SKI is composed of a four-bit type field with the value 0100, followed by the least significant 60 bits of the SHA-1 hash of the value of the public key (excluding the tag, length, and number of unused bit string bits)

The subject key identifier (SKI) provides a unique identification for a certificate's subject when working with XML digital signing. An SKI is an SHA-1 hash of the subject's public key information.

Use the X509SubjectKeyIdentifierHashAlgorithm enumeration to define the type of hash algorithm to use with the X509SubjectKeyIdentifierExtension class when creating an SKI.
