- Mac interface provides applications the functionality of Message Authentication Code (MAC) algorithm, or 'keyed hashing'. 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 secretKey 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 secretKey. HMAC is specified in RFC 2104. Every implementation of the Java platform is required to support the following standard Mac algorithms:
- HmacMD5
- HmacSHA1
- HmacSHA256
- HmacSHA384
- HmacSHA512
- HmacDESCBC
- HmacAESCBC
Mac
object starts out initialized ingetInstance(java.lang.String)
method. The secret secretKey must be set withinit(java.security.Key)
method, prior to process any data. The data is processed withupdate(byte[], int, int)
method. At any pointreset
can be called to reset the digest to its initialized state. Once all the data to be updated has been updated, thedoFinal()
method should be called to complete the hash computation and output the result. ThedoFinal()
method can be called once for a given number of updates. AfterdoFinal()
has been called, theMac
object is reset to its initialized state.Therefore, here are three phases to the use of aMac
object for message authentication:- Initialization with:
- the algorithm name (see above)
- a secret secretKey, which initializes the Mac (see
init(java.security.Key)
)
- Updating. See the
update(byte[], int, int)
method. - Computing a MAC hash for all updated bytes. See the
doFinal()
method.
