Hi,

My elastic stack version is 8.5.3. I am using a fingerprint processor in ingest pipeline to create an MD5 hash. By default, it gives a hash in base64. I want a 128-bit MD5 hash. Is there any solution to this issue?

I don't think this is possible, you may change the `method`, but not how the `method` works.

If using `MD5` generates a base64 hash, you have no option to change that, just changing the method for `SHA-256` or `SHA-512` for example.
