Encryption details

Files passed to Create Encrypted File should be encrypted with DIDWW Public Keys.

Using SDK for encryption

Recommended way of using encryption is to encrypt files in browser. it can be achieved via @didww/encrypt JS library.

If you want to encrypt files on server side it can be done via following:

Ruby Gem

Use the APIv3 Ruby gem to perform file encryption on the server side.

PHP SDK

Use the official PHP SDK to implement server-side encryption.

Java SDK

Use the official Java SDK to implement server-side encryption.

Python SDK

Use the official Python SDK to implement server-side encryption.

To implement encryption manually see figure:

For additional check you need to pass fingerprint of public keys along with encrypted files. You can use our JS library or ruby SDK for that.
