Encryption of Media Files

[aimanabsi]

is there a way to encrypt and send media files like pdf,png via this lib?

Not really. How it's normally done is you encrypt the file using a symmetric encryption method, upload the file to a storage service like s3. Then you send the key and the location of the file to the recipient via the signal library.
