Base64 encode text files effectively and copy it

Question

I have large text files, which should be Base64 encoded. I tried to open it in Notepad++ and encode it with Base64 converter plugin. It was finished in ~10 minutes, but I cannot select output string to use it in JMeter. Files are to long to select it and copy to some converters.

Answer 1

You can use the following functions combination:

• __FileToString() - comes with JMeter already
• __base64Encode() - provided by JMeter Plugins project as a part of Custom JMeter Functions bundle

The syntax would be:

${__base64Encode(${__FileToString(/path/to/your/file,,)},)}

You can install __base64Encode() (and other) functions using JMeter Plugins Manager:
