Fields

Name Value Description
Sha1 0

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 1

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 2

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).

Sha256 3

The SHA-256 hash over the SubjectPublicKeyInfo as described in RFC 7093.

Sha384 4

The SHA-384 hash over the SubjectPublicKeyInfo as described in RFC 7093.

Sha512 5

The SHA-512 hash over the SubjectPublicKeyInfo as described in RFC 7093.

ShortSha256 6

The SHA-256 hash over the subjectPublicKey truncated to the leftmost 160-bits as described in RFC 7093.

ShortSha384 7

The SHA-384 hash over the subjectPublicKey truncated to the leftmost 160-bits as described in RFC 7093.

ShortSha512 8

The SHA-512 hash over the subjectPublicKey truncated to the leftmost 160-bits as described in RFC 7093.

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