r1d2e3c2 rec3e411 50 50 51 51 These days, MSN Messenger clients have to connect to the MS Passport servers 52 through HTTPS. BitlBee can use se rveral SSL libraries for this: GnuTLS, NSS52 through HTTPS. BitlBee can use several SSL libraries for this: GnuTLS, NSS 53 53 (which comes with Mozilla) and OpenSSL. OpenSSL is not GPL-compatible in some 54 54 situations, so using GnuTLS or NSS is preferred. However, especially on *BSD, -
