JMeter interface test-using RSA encryption decryption algorithm

This article describes jmeter encryption parameters using the RSA algorithm

If the test process, some of the interface using RSA encryption algorithm, our JMeter can also be called directly, do not need to develop and remove the encryption code!

See the effect of running

The above code, directly put the encryption results in the variable sign, elsewhere, if you need to invoke the encryption results, only need to use the code: ${sign}

Import org.apache.commons.codec.binary.Base64;
The classes in the JMeter package are introduced, and if this code runs in the JMeter environment, no third-party jar packages need to be loaded
If you are running in eclipse or another environment, you need to replace the class with other Base64, please note!
