Answer 1

Finally i got solution to this question . I am posting the answer here for everyone who need this
I am using a library called aes-encrypt-stream
or you can use crpto library as well or any other. Here

use stream.PassThrough
Here file.stream is my input stream
stream is my outputstream
From this code i am able to reduce memory consumption of server for encryption

const { createEncryptStream, createDecryptStream, setPassword } = require('aes-encrypt-stream');
setPassword(Buffer.from('your key here', 'hex'));
PassThroughStream = require('stream').PassThrough,
stream = new PassThroughStream();
await createEncryptStream(file.stream).pipe(stream);

now stream is encrypted
