# SecureEnclave.MLKEM768.PrivateKey ``` struct PrivateKey ``` ## Topics ### Creating a private key [`static func generate() throws -> SecureEnclave.MLKEM768.PrivateKey`](/documentation/CryptoKit/SecureEnclave/MLKEM768/PrivateKey/generate()) Generates a new random private key. [`init(accessControl: SecAccessControl, authenticationContext: LAContext?) throws`](/documentation/CryptoKit/SecureEnclave/MLKEM768/PrivateKey/init(accessControl:authenticationContext:)) [`init(dataRepresentation: D, authenticationContext: LAContext?) throws`](/documentation/CryptoKit/SecureEnclave/MLKEM768/PrivateKey/init(dataRepresentation:authenticationContext:)) ### Accessing the key’s properties [`let dataRepresentation: Data`](/documentation/CryptoKit/SecureEnclave/MLKEM768/PrivateKey/dataRepresentation) A data representation of the private key. [`let publicKey: MLKEM768.PublicKey`](/documentation/CryptoKit/SecureEnclave/MLKEM768/PrivateKey/publicKey) The corresponding public key. ### Decapsulating shared secrets [`func decapsulate(D) throws -> SymmetricKey`](/documentation/CryptoKit/SecureEnclave/MLKEM768/PrivateKey/decapsulate(_:)) Decapsulates the encapsulated shared secret ### Initializers [`init(accessControl: SecAccessControl) throws`](/documentation/CryptoKit/SecureEnclave/MLKEM768/PrivateKey/init(accessControl:)) [`init(dataRepresentation: D) throws`](/documentation/CryptoKit/SecureEnclave/MLKEM768/PrivateKey/init(dataRepresentation:)) ## Relationships ### Conforms To [`Sendable`](/documentation/Swift/Sendable) [`SendableMetatype`](/documentation/Swift/SendableMetatype) [`KEMPrivateKey`](/documentation/CryptoKit/KEMPrivateKey) --- Copyright © 2026 Apple Inc.
