HMAC

public class HMAC : Updatable

Calculates a cryptographic Hash-Based Message Authentication Code (HMAC).


                    
                    
                    status

Status of the calculation

Swift

public internal(set) var status: Status { get }


                    
                    
                    init(using:key:)

Creates a new HMAC instance with the specified algorithm and key.

Swift

public init(using algorithm: Algorithm, key: Data)

`algorithm`	Selects the algorithm
`key`	Specifies the key as Data


                    
                    
                    init(using:key:)

Creates a new HMAC instance with the specified algorithm and key.

Swift

public init(using algorithm: Algorithm, key: NSData)

`algorithm`	Selects the algorithm
`key`	Specifies the key as NSData


                    
                    
                    init(using:key:)

Creates a new HMAC instance with the specified algorithm and key.

Swift

public init(using algorithm: Algorithm, key: [UInt8])

`algorithm`	Selects the algorithm
`key`	Specifies the key as byte array.


                    
                    
                    init(using:key:)

Creates a new HMAC instance with the specified algorithm and key string. The key string is converted to bytes using UTF8 encoding.

Swift

public init(using algorithm: Algorithm, key: String)

`algorithm`	Selects the algorithm
`key`	Specifies the key as String


                    
                    
                    update(from:byteCount:)

Updates the calculation of the HMAC with the contents of a buffer.

Swift

public func update(from buffer: UnsafeRawPointer, byteCount: size_t) -> `Self`?


                                buffer

Update buffer
