Type members

• static func authenticationCode<D>(for: D, using: SymmetricKey) -> MAC

  Computes a message authentication code for the given data.

• static func isValidAuthenticationCode(MAC, authenticating: UnsafeRawBufferPointer, using: SymmetricKey) -> Bool

  Returns a Boolean value indicating whether the given message authentication code is valid for a block of data stored in a buffer.

• static func isValidAuthenticationCode<D>(MAC, authenticating: D, using: SymmetricKey) -> Bool

  Returns a Boolean value indicating whether the given message authentication code is valid for a block of data.

• static func isValidAuthenticationCode<C, D>(C, authenticating: D, using: SymmetricKey) -> Bool

  Returns a Boolean value indicating whether the given message authentication code represented as contiguous bytes is valid for a block of data.

Instance members

• func finalize() -> MAC

  Finalizes the message authentication computation and returns the computed code.

• func update<D>(data: D)

  Updates the message authentication code computation with a block of data.
