- openssl for DEBIAN
- ----------------------
-
- openssl replaces ssleay.
-
- The application links to openssl like req, ca, verify and s_client
- have been removed.
-
- Instead of `<application>` please call now `openssl <application>`
-
- eg:
- instead of `req` please call `openssl req`

-
- Some algorithms used in the library are covered by patents. As
- a result, the following algorithms in libcrypto have been disabled:
- - RC5
- - MDC2
- - IDEA

- Self-signed certs and webservers:
- ---------------------------------
-
- If you get with a selfsigned certificate and a webserver:
- > "The certificate is not approved for the attempted operation."
