RESTRICTED= variables that were predicated on former U.S. export
regulations. Add CRYPTO=, as necessary, so it's still possible to
exclude all crypto packages from a build by setting MKCRYPTO=no
(but "lintpkgsrc -R" will no longer catch them).
Specifically,
- - All packages which set USE_SSL just lose their RESTRICTED
variable, since MKCRYPTO responds to USE_SSL directly.
- - realplayer7 and ns-flash keep their RESTRICTED, which is based
on license terms, but also gain the CRYPTO variable.
- - srp-client is now marked broken, since the distfile is evidently
no longer available. On this, we're no worse off than before.
[We haven't been mirroring the distfile, or testing the build!]
- - isakmpd gets CRYPTO for RESTRICTED, but remains broken.
- - crack loses all restrictions, as it does not evidently empower
a user to utilize strong encryption (working definition: ability
to encode a message that requires a secret key plus big number
arithmetic to decode).
as pointed out by Bjoern Labitzke <hermit@cs.tu-berlin.de> in PR/7359.
While I'm at it, also correct the behaviour when invoked as "pgp5"
(give usage, not unhelpful 'invoked with unknown symbolic link').
Based on pr 6684 by Martin J. Laubach with heavy refining/fixing by myself.
XXX This package needs still some tweaking to work with rsaref.
XXX Maybe some US citizen developer can take over?
XXX At least its usefull to non-US ppl.
