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.
