HiTeam, I am working on image signing and verification. For feasibility study I have selected gnupg. *Steps I executed..* 1) made pair of private and public key (RSA4096) 2) I am able to digitally sign an image using "detach". Getting fyl.sig as output file. 3) exported the public key using --export -a (ascii armour).
*Step I want to execute at verification side.. But not aware.* 1) Want to find 'n' and 'e' values from a public key which is imported from a signed machine. Public key is in ascii armor format. want to write my public key in below format. ///////////////////////////////////Copied from rsa.c/////////////////////////////////////////////////////////////// static const char sample_public_key[] = " (public-key" " (rsa" " (n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e #010001#)))"; ////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// But not sure how to decode imported ascii armor public key in above format. I tried to find in gnupg documents but not able to get information. Please suggest. Regards, Vishal -- *Thanks & Regards,Vishal RanaMobile :09422123401*
