haskell TLS
|
|
|
|
|
===========
|
|
|
|
|
|
|
|
|
|
This library provide native Haskell TLS and SSL protocol implementation for server and client.
|

Description
|
|
|
|
|
-----------
|
|
|
|
|
|
|
|
|
|
This provides a high-level implementation of a sensitive security protocol,
|
|
|
|
|
eliminating a common set of security issues through the use of the advanced
|
|
|
|
|
type system, high level constructions and common Haskell features.

|
|
|
* client certificates.

Common Issues
|
|
|
|
|
-------------
|
|
|
|
|
|
|
|
|
|
The tools mentioned below are all available from the tls-debug package.
|
|
|
|
|
|
|
|
|
|
* Certificate issues
|
|
|
|
|
|
|
|
|
|
It's useful to run the following command, which will connect to the destination and
|
|
|
|
|
retrieve the certificate chained used.
|
|
|
|
|
|
|
|
|
|
tls-retrievecertificate -d <destination> -p <port> -v -c
|
|
|
|
|
|
|
|
|
|
As an output it will print every certificates in the chain and will gives the issuer and subjects of each.
|
|
|
|
|
It creates a chain where issuer of certificate is the subject of the next certificate part of the chain:
|
|
|
|
|
|
|
|
|
|
(subject #1, issuer #2) -> (subject #2, issuer #3) -> (subject #3, issuer #3)
|
|
|
|
|
|
|
|
|
|
A "CA is unknown" error indicates that your system doesn't have a certificate in
|
|
|
|
|
the trusted store belonging to any of the node of the chain.
