Certs

tor_cell::chancell::msg

Struct Certs 

Source 
pub struct Certs { /* private fields */ }
Expand description

A Certs message is used as part of the channel handshake to send additional certificates.

These certificates are not presented as part of the TLS handshake. Originally this was meant to make Tor TLS handshakes look “normal”, but nowadays it serves less purpose, especially now that we have TLS 1.3.

Every relay sends this message as part of channel negotiation; clients do not send them.

Implementations§

Source§

impl Certs

Source

pub fn new_empty() -> Self

Return a new empty certs cell.

Source

pub fn push_cert_body<B>(&mut self, certtype: CertType, cert: B)
where B: Into<Vec<u8>>,

Add a new encoded certificate to this cell.

Does not check anything about the well-formedness of the certificate.

Source

pub fn cert_body(&self, tp: CertType) -> Option<&[u8]>

Return the body of the certificate tagged with ‘tp’, if any.

Source

pub fn parse_ed_cert(&self, tp: CertType) -> Result<KeyUnknownCert>

Look for a certificate of type ‘tp’ in this cell; return it if there is one.
