JDK 14.0.2 General-Availability Release. This page provides production-ready open-source builds of the Java Development Kit, version 14, an implementation of the Java SE 14 Platform under the GNU General Public License, version 2, with the Classpath Exception. Commercial builds of JDK 14.0.2 from Oracle, under a non-open-source license, can be found at the Oracle Technology Network. 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., SHA256 or SHA384, 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: HmacSHA1.All Implemented Interfaces:CloneableThis 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.
