Algorithm execution with Rails

Hello,

I have a doubt , when I develop an app that run a encryption algorithm ,
this algorithm run first on the client computer and the send the data to
server , or is executed directly on server , enabling interception of
the plain text?

Thanks,

I’m sorry, I don’t really understand your question. All of the things
you mention are possible. It depends on where the encryption is
performed. Encryption can be done on the client using JavaScript or it
can be done on the server using Ruby.

If you are worried about someone intercepting the page content displayed
by the browser then that’s the exact purpose of SSL/TLS. Everything the
user would see in their browser window gets encrypted before egress onto
the Internet and is only decrypted once it reaches the server. No one
intercepting the traffic sent between the client browser and the web
server can read anything. All they will capture will be pseudo-random
noise.

Give us specifics about what you are tying to do and we can tell you the
best solution for that scenario.
