certificate - Trusting app signatures -


i gather developers (except perhaps larger companies) use self-signed certificates sign apk. since required app installation, ability sign app available anyone. simple use keytool , jarsigner java sdk. these self-signed certs , associated private keys not guarantee degree of security unless can somehow match certificate trust. there no ability revocate these self-signed certificates (no crl) , there no "issuer" (since certs self-signed) "vouches" in way identity of certificate/key holder signs code.

so andriod platform have or plan have ability prevent installation of apps signed particular signature? or enable settings allowing installation of apps signed cert/key issued list of trusted ca (certificate-authorities/issuers) ? however, there security available: in settings/security can prevent installation of (even signed , manually copied sim) unless comes play store, default setting. might able install user certificate , allow apps signed cert install (even if play store?).

i dont think purpose of these certificates ensure identity normal certificate signed ca would. seems me purpose of certificates have security factor ensure person published app first time 1 publishes updates.

without hacks google account able publish malicious updates entire user base.

so two-factor authentication publishing.

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
