Jul 14, 2020. 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.

Adobe® Flash® Builder® 4.7, which is an Integrated Development Environment (IDE) for developing games and applications using ActionScript and Flex framework runs on Java 6. If you do not have Java 6 on your machine Flash Builder does not launch and instead displays this error.

Steps to follow on Windows

  1. Install Java 1.7/1.8.
  2. Copy the jre7/jre8 folder inside the Java folder. Replace the jre folder inside flash builder installation folder with the copied one.
  3. Restart Flash Builder.

Steps to follow on Mac

    1. Set your JAVA_HOME to Java 7 or Java 8 as per the correct paths on your machine.

    1. Open JVM’s Info.plist at $JAVA_HOME/../Info.plist and add the highlighted lines to JVMCapabilities array:
    2. Create a symlink for libjvm.dylib as follows:

Note: Correct the version number (in jdk1.7.0_79.jdk) path in the above example to make it point to the correct path on your machine.

  1. Set java.library.path by adding the following lines at the end of “/Applications/Adobe Flash Builder 4.7/Adobe Flash Builder 4.7.app/Contents/MacOS/Adobe Flash Builder 4.7.ini”.

Restart your machine and launch Flash Builder.

Possible error on Mac

If you are trying to launch Flash Builder on Mac OS 10.12 and you see an error such as:

Locate a directory named “p2” at /Applications/Adobe Flash Builder 4.7/ and delete it. Flash Builder should now launch.

Flash Builder 4.7 crash on Mac OS 10.13 (High Sierra)

With the recent update of Mac OS 10.13 (High Sierra), “Flash Builder stopped working” error is encountered when you click Project-> “Export Release Build”.

If you are facing this issue follow the steps below:

  1. Download the attached zip (fb.zip) which contains 2 jar files.
  2. Copy the 2 jar files and paste them at the location: “/Applications/Adobe Flash Builder 4.7/eclipse/plugins/”.
  3. Restart Flash Builder.

All Implemented Interfaces:
Cloneable
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., 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:

Lang
  • HmacSHA1
  • HmacSHA256
These algorithms are described in the Mac section of the Java Security Standard Algorithm Names Specification. Consult the release documentation for your implementation to see if any other algorithms are supported.
