import CryptoA cryptography library for Swift.
struct HMAC<H> where H : HashFunctionA hash-based message authentication algorithm.
protocol DataProtocol : RandomAccessCollection where Self.Element == UInt8, Self.SubSequence : DataProtocolinit(key: SymmetricKey) Creates a message authentication code generator.
static func authenticationCode<D>(for data: D, using key: SymmetricKey) -> MAC where D : DataProtocol Computes a message authentication code for the given data.
static func isValidAuthenticationCode(_ mac: MAC, authenticating bufferPointer: UnsafeRawBufferPointer, using key: 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>(_ authenticationCode: MAC, authenticating authenticatedData: D, using key: SymmetricKey) -> Bool where D : DataProtocol Returns a Boolean value indicating whether the given message authentication code is valid for a block of data.
static func isValidAuthenticationCode<C, D>(_ authenticationCode: C, authenticating authenticatedData: D, using key: SymmetricKey) -> Bool where C : ContiguousBytes, D : DataProtocol Returns a Boolean value indicating whether the given message authentication code represented as contiguous bytes is valid for a block of data.
func finalize() -> MAC Finalizes the message authentication computation and returns the computed code.
