Can MetaDefender Core process Base64 Content?

Yes, MetaDefender Core is capable of decoding and processing Base64 Encoded files.

It is possible to send a Base64 Encoded string using the API Call features.

For example, we took the following PDF File and encoded it:

Resulting in a string:

Using Postman, we prepared a POST message to <protocol>://<md_core_address>:8008/file URI, enabling Content-Encoding header, with the base64 as the given value.

And pasted the Base64 Encoded string in an empty file which we uploaded as binary:

After which we have sent the message and obtained a result:

Additionally, we can send the string as a Raw Body base64 text string:

Checking the MetaDefender Core’s History, we have found that the sent file has been correctly decoded, for both methods:

We can check the HASH against the original file and see they are all the same:
