In our application we are reading mail body which client have replied to our mail address and saved it to our database table.
When some clients reply on our email address mail body contains base64 string with header Content-Transfer-Encoding: base64.
Can I know if there is any configuration setting on mail server that it will convert the base64 string into image.
This problem occurs only with some clients not all. I am guessing that these clients have base64 image in their signature.
Any help will be much appreciated.
Please check below image for what response we get in our application.
It isn't the server that needs to convert anything. base64 encoded images are already images.
It is your client, whatever you are using to view the emails that needs to interpret the embedded base64 encoding and display it as an image to you.

Hello how to get files data in base64 from slack channel.
When user add the files to slack channel the response contains the URL of the files. But its possible to get content in base64 ..?
I am trying to simulate email from a secure email account using Jmeter.
Any attachments that I send are not being encrypted using Base64 as the emails are when sent from the same email address manually. this is causing a problem whereby the application that picks up the attachment to process fails to decode the email.
How can I get Jmeter to submit the email with attachment with content-transfer-encoding of base64?
If all you need to do is to perform base64-encoding of the message body - you can perform it via __base64Encode() function available via Custom JMeter Functions bundle and can be installed using JMeter Plugins Manager.
However be aware that it can be easily decoded back even using online tools so I doubt that it makes sense to rely on Base64 for security.
You can always call underlying Java Mail API functions from JSR223 Test Elements if JMeter cannot fully fulfill your requirements.
I have captured request content of a mobile app (iphone) through a proxy (Charles Proxy), but the content seems to be encoded which I want to decode into human-readable format. As the source of the encoding format is not known, I cannot decode it, I have tried several online tools with different source formats but none of it decode it properly. How to decode such content properly?

UPDATE:
The request/response content is encrypted by java cryptography before sending it in the network using the AES cipher algorithm and cipher transformation is done with AES/CBC/PKCS5Padding. I am able to decrypt it by debugging APK code and finding the secret key used to encrypt the content. It's really another level of encryption before sending it in the network.
How can I have the user upload an image, then without sending it to a server give me the base64 version of the image?
In a IDP initiated environment the payload is not able to decode it.
Getting exception in decoder.decode(samlContext);
So after analysing I found that the payload is encrypted with URL encoding after Base64 encoding.
Any way there if I can consume this payload and decode it.
This issue I was facing due to some copy paste issue, now solved.
