(1.3.6.1.4.1.27630.2.1.1.59 DESC 'osiICardMasterKey' )

osiICardMasterKey attribute OID of openosi.schema for X500 / LDAP directory

Notation

This object identifier (OID) describes osiICardMasterKey attribute of openosi.schema .

ASN1 notation: {iso(1) identified-organization(3) dod(6) internet(1) private(4) enterprise(1) openosi(27630) identification(2) schema(1) attribute(1) osiICardMasterKey(59)}
URN notation: urn:oid:1.3.6.1.4.1.27630.2.1.1.59
IETF DOT notation: 1.3.6.1.4.1.27630.2.1.1.59
BNF notation (RFC822 Backus-Naur form): ( 1.3.6.1.4.1.27630.2.1.1.59 DESC 'osiICardMasterKey' )
Description: osiICardMasterKey attribute OID of openosi.schema for X500 / LDAP directory

Definition

osiICardMasterKey attribute is a container for attributes types conforming with RFC4512 specification.

DESC 'sha256(base64binary(ICard Master key))'

Each self-issued information card contains a random secret, called the "master key" that is used as the secret entropy for computing the token-signing key (up to 512 bits in length).

This required element contains the base64-encoded "master key" (or secret entropy) for a card from which the token-signing RSA key pair is generated for a relying party. If the card is PIN-protected, this element contains the master key encrypted with the PIN (see osiICardPinDigest). The osiICardMasterKey is used for computation of the osiPrivatePersonalID.

This element MUST contain a base64-encoded byte array comprising the encryption parameters and the encrypted master key serialized as per the structure summarized in the following table.

Field Offset Size (bytes)
Version (for internal use) 0 1
Salt used for key-derivation method 1 16
Iteration count used for key-derivation method 17 4
Initialization Vector (IV) used for encryption 21 16
Encrypted master key 37 Master key length
