ios - Objective-C with OpenSSL - Cannot set RSA Key -


i trying use add rsa encryption app using openssl, cannot certificate load. in app, public key certificate distributed server , need take key , use decrypt content encrypted barcodes app scan.

the reason why choosing openssl on security library require ecdsa validation, unsupported natively.

i have tried numerous methods key load. openssl pem_read_rsa_pubkey method requires file pointer. when run code below, crashes exc_bad_access attempt access key.

nsstring * path = [[nsbundle mainbundle] pathforresource:  @"public" oftype: @"pem"]; file *f = fopen([path cstringusingencoding:1],"r"); if (f == null)     nslog(@"%@", [path stringbyappendingstring:@" not found"]);  rsa *rsa = pem_read_rsa_pubkey(f,null,null,null);  fclose(f);  nslog (@"%d keycheck", rsa_check_key(rsa));

i have included following headers openssl library

#include <openssl/opensslv.h> #include <openssl/crypto.h> #include <openssl/rsa.h> #include <openssl/pem.h>

i have other openssl methods such md5, base64 encode/decode, sha1 , ecdsa code working ok, it's passing in rsa certificate has got me stumped!

the public.pem key file contains key:

-----begin public key----- migfma0gcsqgsib3dqebaquaa4gnadcbiqkbgqc+ynz7evj0f+iogmlme/j/mph4 7bxriudtjcos99j82il3ww9ubm28yomhypdi23wpdhr80ugabwanmquzwvykjqd4 z4d0sj0nvw3ddgz4gs57zfqlvggdvhzavimfs7qdxij1o8gmuxwsezv2zpmijdnf zbol5zztqnfk89rnnqidaqab -----end public key-----

your program read rsa public key fine.

problem with

rsa_check_key

please read rsa_check_key here.

it not work on public key. need private key function. why crashing since have private key. sorry inconvenience due previous answers.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
