This class provides the functionality of a 'Message Authentication Code' (MAC) algorithm. A MAC provides a way to check the integrity of information transmitted over or stored in an unreliable medium, based on a secret key. Typically, message authentication codes are used between two parties that share a secret key in order to validate information transmitted between these parties. A MAC mechanism that is based on cryptographic hash functions is referred to as HMAC. HMAC can be used with any cryptographic hash function, e.g., MD5 or SHA-1, in combination with a secret shared key.

HMAC is specified in RFC 2104. Every implementation of the Java platform is required to support the following standard Mac algorithms:. HmacMD5. HmacSHA1. HmacSHA256 These algorithms are described in the of the Java Security Standard Algorithm Names Specification.

Consult the release documentation for your implementation to see if any other algorithms are supported. Returns a Mac object that implements the specified MAC algorithm. This method traverses the list of registered security Providers, starting with the most preferred Provider. A new Mac object encapsulating the MacSpi implementation from the first Provider that supports the specified algorithm is returned. Note that the list of registered providers may be retrieved via the method.

Implementation Note: The JDK Reference Implementation additionally uses the jdk.security.provider.preferred property to determine the preferred provider order for the specified algorithm. This may be different than the order of providers returned. Parameters: algorithm - the standard name of the requested MAC algorithm.

See the Mac section in the for information about standard algorithm names. Returns: the new Mac object Throws: - if no Provider supports a MacSpi implementation for the specified algorithm - if algorithm is null See Also:.

getInstance public static final getInstance( algorithm, provider) throws. Returns a Mac object that implements the specified MAC algorithm. A new Mac object encapsulating the MacSpi implementation from the specified provider is returned. The specified provider must be registered in the security provider list. Note that the list of registered providers may be retrieved via the method. Parameters: algorithm - the standard name of the requested MAC algorithm. See the Mac section in the for information about standard algorithm names.

Provider - the name of the provider. Returns: the new Mac object Throws: - if the provider is null or empty - if a MacSpi implementation for the specified algorithm is not available from the specified provider - if the specified provider is not registered in the security provider list - if algorithm is null See Also:.

Parameters: algorithm - the standard name of the requested MAC algorithm. See the Mac section in the for information about standard algorithm names. Provider - the provider. Returns: the new Mac object Throws: - if the provider is null - if a MacSpi implementation for the specified algorithm is not available from the specified Provider object - if algorithm is null See Also:.

getProvider public final getProvider. Finishes the MAC operation.

A call to this method resets this Mac object to the state it was in when previously initialized via a call to init(Key) or init(Key, AlgorithmParameterSpec). That is, the object is reset and available to generate another MAC from the same key, if desired, via new calls to update and doFinal.

(In order to reuse this Mac object with a different key, it must be reinitialized via a call to init(Key) or init(Key, AlgorithmParameterSpec). Returns: the MAC result. Throws: - if this Mac has not been initialized. doFinal public final void doFinal(byte output, int outOffset) throws. Finishes the MAC operation. A call to this method resets this Mac object to the state it was in when previously initialized via a call to init(Key) or init(Key, AlgorithmParameterSpec). That is, the object is reset and available to generate another MAC from the same key, if desired, via new calls to update and doFinal.

(In order to reuse this Mac object with a different key, it must be reinitialized via a call to init(Key) or init(Key, AlgorithmParameterSpec). The MAC result is stored in output, starting at outOffset inclusive. Parameters: output - the buffer where the MAC result is stored outOffset - the offset in output where the MAC is stored Throws: - if the given output buffer is too small to hold the result - if this Mac has not been initialized. doFinal public final byte doFinal(byte input) throws. Processes the given array of bytes and finishes the MAC operation. A call to this method resets this Mac object to the state it was in when previously initialized via a call to init(Key) or init(Key, AlgorithmParameterSpec).

That is, the object is reset and available to generate another MAC from the same key, if desired, via new calls to update and doFinal. (In order to reuse this Mac object with a different key, it must be reinitialized via a call to init(Key) or init(Key, AlgorithmParameterSpec).

Parameters: input - data in bytes Returns: the MAC result. Throws: - if this Mac has not been initialized. reset public final void reset. Summary:. Nested.
