Defines the type of hash algorithm to use with the System.Security.Cryptography.X509Certificates.X509SubjectKeyIdentifierExtension class.
Syntax
Remarks
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 System.Security.Cryptography.X509Certificates.X509SubjectKeyIdentifierHashAlgorithm enumeration to define the type of hash algorithm to use with the System.Security.Cryptography.X509Certificates.X509SubjectKeyIdentifierExtension class when creating an SKI.

The 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). |
| Sha1 |
The 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). |
| ShortSha1 |
The 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) |
