This is true when the subject public key is used to verify digital signatures used to provide a non-repudiation service that protects against the signing entity denying some action. This does not cover signatures used in certificates (covered by keyCertSign) or in CRLs (cRLSign).
var nonRepudiation: Bool { get set }import X509A library for working with X.509 certificates.
struct KeyUsageDefines the purpose of the key contained in the certificate.
var keyCertSign: Bool { get set }This is true when the subject public key is used for verifying signatures on certificates.
var cRLSign: Bool { get set }This is true when the subject public key is used for verifying signatures on certificate revocation lists.
@frozen struct BoolA value type whose instances are either true or false.
init() Construct a KeyUsage extension with no usages set.
init(_ ext: Certificate.Extension) throws Create a new KeyUsage object by unwrapping a Extension.
init(digitalSignature: Bool = false, nonRepudiation: Bool = false, keyEncipherment: Bool = false, dataEncipherment: Bool = false, keyAgreement: Bool = false, keyCertSign: Bool = false, cRLSign: Bool = false, encipherOnly: Bool = false, decipherOnly: Bool = false) Construct a KeyUsage extension with some usages set.
var dataEncipherment: Bool { get set }This is true when the subject public key is used to encrypt raw data directly, without the use of an intervening symmetric cipher.
var debugDescription: String { get }var decipherOnly: Bool { get set }This only has meaning when the keyAgreement field is also true. When true in that case, the subject public key may only be used for decrypting data while performing key agreement.
var description: String { get }var digitalSignature: Bool { get set }This is true when the subject public key is used for verifying digital signatures, other than signatures used in certificates (covered by keyCertSign) or in CRLs (covered by cRLSign).
var encipherOnly: Bool { get set }This only has meaning when the keyAgreement field is also true. When true in that case, the subject public key may only be used for encrypting data while performing key agreement.
var keyAgreement: Bool { get set }This is true when the subject public key is used for key agreement.
var keyEncipherment: Bool { get set }This is true when the subject public key is used to encrypt private or secret keys, e.g. for key transport.
