ios - Encrypt/Decrypt text using existing key pair -

-

this has been extremely confusing me. have process generate public/private key pair using php. code that:

$config = array(     "digest_alg" => "sha512",     "private_key_bits" => 4096,     "private_key_type" => openssl_keytype_rsa, );  // create private , public key $res = openssl_pkey_new($config);

and here example of generated output:

-----begin public key----- miicijanbgkqhkig9w0baqefaaocag8amiiccgkcagea1ufdaaadquwpublw8vce wegwdl3khrc/yzgwi8op72bq2zzgxzncxhdmwgfxax4eblwwipbbtsnboi6urieb bpnis/ei/ajgbko/yj2idkfnxmy6xbxwpunqeq2tjeddnxb2y0g896gijfwn8fzk ollspofks5ipaxdylnlwr5stgxweexc2gpaplap00d3xg/qhsm2fubvljhqreis1 mwyajg0ev72u3ypp0ok19z0ylbfrhaubne+mx6tsnb9xqawe4gksbnso06lz4n9j k7sg16dxpuekho8pdzwun2qbig3fgc3ibnmr2u6lux218bgtiggdvoaar1e3cof1 vmli3ads/evejzds3gkg1rxcrbcfajnwe5yl1j+nxeffbedr2flx6chspzfv1x3p dumr1hb/ndslhwnj7qqqqhtgfpdfql4ejgfguvygid1k0u/8b6vqk0k9jku5nrn5 d1e3h7qjm/kbbohnsi/0gbuuyrktipxu5b9ex51wpa80fbmc/ao6dewlnu59w134 ygu5kfi1qfi0w5xusa3iu91ak2thyezzjniz0rvmojezlbtxcv26e5gmdjuqn//d um/qe6akck382yygdrivgujxb3a/iwp5ihkalzazawxgrc6epvcbqfgzu/t5ebhi dt279sgtgq+olotfvnknml0caweaaq== -----end public key-----

so save these 2 files server storing keys. when app runs, receives appropriate public/private keys this, in format, in text format. here question: how use these existing keys, based upon algorithm (sha512, 4096 bits) in function both encrypt , decrypt nsstrings? understanding, have work keys before can use them ios - strip headers, convert base64, eg?

in short, looking create 2 functions. 1 can decrypt , 1 can decrypt - both should take certificates in text format above (or converted else) text encrypted , return encrypted/decrypted version.

you aren't using sha512 encryption/decryption, value used if going create certificate or certificate request tied keypair.

here breakdown on parameters used:

"digest_alg" => "sha512"

for digest in certificate.

"private_key_bits" => 4096, "private_key_type" => openssl_keytype_rsa,

this means generated rsa-4096 key pair. make sure encrypt/decrypt using rsa-4096.

windows - Single EXE to Install Python Standalone Executable for Easy Distribution -

i used pyinstaller create standalone exe file pyqt project. did not use single file option because exe created single file option takes long open. therefore, pyinstaller created dist folder contains bunch of files including program.exe file. create setup.exe file place contents of dist folder in program directory , create shortcut in start menu , on desktop. want super simple user. maybe setup.exe files when download program cnet. found inno-setup, looks promising. however, not know if there special considerations because program standalone program create python/pyqt program. thanks! have experience task? there program using task not know about? inno-setup or nsis easiest use. tell them files include , put them , create nice installer you. wrote short tutorial on experiences using innosetup might find helpful: http://www.blog.pythonlibrary.org/2008/08/27/packaging-wxpymail-for-distribution/ note tutorial based around wxpython app wrote, concepts same.
