{"name":"tcb","summary":"Alternative password shadowing scheme","description":"The tcb package contains core components of our tcb suite implementing the alternative\npassword shadowing scheme on Openwall GNU Linux (Owl). It is being made available\nseparately from Owl primarily for use by other distributions.\n\nThe package consists of three components: pam_tcb, libnss_tcb, and libtcb.\n\npam_tcb is a PAM module which supersedes pam_unix. It also implements the tcb password\nshadowing scheme. The tcb scheme allows many core system utilities (passwd(1) being\nthe primary example) to operate with little privilege. libnss_tcb is the accompanying\nNSS module. libtcb contains code shared by the PAM and NSS modules and is also used\nby user management tools on Owl due to our shadow suite patches.","homepage_url":"https://www.openwall.com/tcb/","license":"BSD-3-Clause","attribute_paths":["tcb"],"releases":[{"version":"1.2","last_updated":"2026-09-29T03:29:29Z","platforms":[{"arch":"arm64","os":"Linux","system":"aarch64-linux","attribute_path":"tcb","commit_hash":"b6c8664de9b6cc07fe5666a29f91884ba81197c4","date":"2026-09-29T03:29:29Z","outputs":[{"name":"out","path":"/nix/store/lbbvf2d16q4mzbbp5ayl89nrkdc85nwx-tcb-1.2","default":true},{"name":"bin","path":"/nix/store/d0an6m6xq2dlxkjmjvi48kpdjm0ixf9f-tcb-1.2-bin","default":true},{"name":"man","path":"/nix/store/4iybc84am7aph7lv4hxyjp7i04jvyn5h-tcb-1.2-man","default":true},{"name":"dev","path":"/nix/store/i7vakli55h6zqfhwra96gcbwqi7csfzl-tcb-1.2-dev"}],"broken":false,"insecure":false},{"arch":"x86-64","os":"Linux","system":"x86_64-linux","attribute_path":"tcb","commit_hash":"b6c8664de9b6cc07fe5666a29f91884ba81197c4","date":"2026-09-29T03:29:29Z","outputs":[{"name":"out","path":"/nix/store/53pxakn1y52i0m0fklnb8xfhas93l3fi-tcb-1.2","default":true},{"name":"bin","path":"/nix/store/dhsbkjp5v47z5g9j46j5q05kkgzb38wl-tcb-1.2-bin","default":true},{"name":"man","path":"/nix/store/8h4sy6rn81rs5xy0f3007mc9madq1i23-tcb-1.2-man","default":true},{"name":"dev","path":"/nix/store/va91cv1prhiij7k4c9x44859kv0nr53r-tcb-1.2-dev"}],"broken":false,"insecure":false}],"platforms_summary":"Linux","outputs_summary":"bin (Linux only), man (Linux only), out (Linux only), dev (Linux only)","prerelease":false,"broken":false,"insecure":false}]}
