SubjectPublicKeyInfo

internal final class SubjectPublicKeyInfo

The SubjectPublicKeyInfo class represents a data structure defined by the ASN.1 notation. It is used to encapsulate information related to a public key.

According to the ASN.1 definition, a SubjectPublicKeyInfo consists of two components: an AlgorithmIdentifier and a subjectPublicKey of type BIT STRING.

The data structures SubjectPublicKeyInfo and AlgorithmIdentifier are defined as follows:

 SubjectPublicKeyInfo ::= SEQUENCE {
    algorithm  AlgorithmIdentifier,
    subjectPublicKey    BIT STRING
 }

 AlgorithmIdentifier ::= SEQUENCE {
    algorithm OBJECT IDENTIFIER,
    parameters ANY DEFINED BY algorithm OPTIONAL
 }

Note

This class encapsulate just the public key. The algorithm data structure is not included here.

  • Declaration

    Swift

    private(set) var publicKey: OpaquePointer { get }

  • Declaration

    Swift

    private(set) var subjectPublicKeyBytes: [UInt8] { get }

  • Initializes a SubjectPublicKeyInfo object from an ASN1Node.

    Throws

    An error if there is an issue with decoding the provided ASN.1 node into a public key.

    Declaration

    Swift

    internal init(from node: ASN1Node) throws

    Parameters

    node

    An ASN1Node containing the encoded public key information.

  • Declaration

    Swift

    deinit
