equery u tor [ Legend : U - final flag setting for installation] [ : I - package is installed with flag ] [ Colors : set, unset ]

Found these USE flags for net-vpn/tor-0.3.5.3_alpha: U I

- caps : Use Linux capabilities library to control privilege
- libressl : Use dev-libs/libressl instead of dev-libs/openssl when applicable (see also the ssl useflag)

- lzma : Support for LZMA (de)compression algorithm

- scrypt : Use app-crypt/libscrypt for the scrypt algorithm

- seccomp : Enable seccomp (secure computing mode) to perform system call filtering at runtime to increase security of programs

- systemd : Enable use of systemd-specific libraries and features like socket activation or session tracking
- test : Enable dependencies and/or preparations necessary to run tests (usually controlled by FEATURES=test but can be toggled independently)
- tor-hardening : Compile tor with hardening on vanilla compilers/linkers
- zstd : Use app-arch/zstd for compression
