| Member name | Description | |
|---|---|---|
| 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) | |
| CapiSha1 | 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). |
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.
