comment X.509 CSR: Why does CA remove signature?
btw: I've asked this question because I'm developing an app which creates a self-signed certificate for the user. This cert needs to be "confirmed" by a central CA. How does it work: The app sends the self-signed cert to the CA which issues a new cert with the users public key in it. This process is very simple and also I would have no clue how to implement CSR in different languages (javascript, perl etc..)

comment X.509 CSR: Why does CA remove signature?
At the moment afaik X.509 does not allow to attach a second signature to a self-signed certificate. In "my world" you would be able to send a self-signed certificate to the CA (since I'm a web developer, for example to an URI www.myca.com/cert/sign), then the CA adds additional attributes to it and sign this "extended cert" with its own private key.

comment X.509 CSR: Why does CA remove signature?
Now we have 2 formats: CSR and X.509. In my world only X.509 would exist but in two different "flavors": self-signed certificates and self-signed certificates which are signed by a CA (the CA only adds additional attributes and its signature to it).

comment Can you help me understand what a cryptographic “salt” is?
"Salt is usually assumed to be known to the attacker" -> Who is assuming this?
