You may have missed the openSSL wiki <http://wiki.openssl.org/index.php/Main_Page> which is not always obvious to reach when you start ….
Do not forget to initialize openSSL in your code as explained at http://wiki.openssl.org/index.php/Libcrypto_API A good place to get a grip on the relevant functions is from http://wiki.openssl.org/index.php/Documentation_Index Also look at examples in source code bundles under openssl\demos There's an intro to EVP crypto functions at http://wiki.openssl.org/index.php/EVP ; they provide a higher level API over RSA_xxx and others (which may better match your problem context than the lower level use), so don't hesitate to navigate source code to see how the lower level functions are used… You may also look at the openSSL command line source code to see how each RSA encrypt/decrypt operation is invoked… I must acknowledge the documentation has its logic but puzzling when you start and often requires to reverse engineer source code to find the details… Enjoy Bernard H From: owner-openssl-us...@openssl.org [mailto:owner-openssl-us...@openssl.org] On Behalf Of Fischel Sent: Tuesday, October 28, 2014 3:32 PM To: openssl-users@openssl.org Cc: ffajbus...@bas.com.ar Subject: Help Hi: Where could find some example to see how this functions are used RSA_generate_key_ex RSA_public_encrypt RSA_private_decrypt Thank's a lot
