Dear all,
I am terribly sorry for keep spamming you with these questions. I am too
fresh and too new to OpenSSL cryptography, and wishing desperately for some
documents (I have looked at the SSLeay Documentation) or some information on
this useful technology.
I really appreciate your help, advices and time for solving my problems.
Till now, most of my problems are solved because of your valuable effort.
Now, I have several questions which I guess I could solve myself (if I am
really good in OpenSSL technology).
1. I get bothered by the unsigned char * and char *. I have to decrypt a
symmetric key with a RSA private key. Now, the symmetric key is encoded by
Base64 form. It basically is char *. Thanks to Yue's help, I manage to
decode the char * using BIO routines. Now, I am not sure I could extract the
private key from P12, and I also not sure how to decrypt the char * of key
using that private key... ... I tried to use EVP routine (EVP_PKEY_decrypt)
but as I said the unsigned thing really bothers me, and the whole
application crashed when I run it... PLEASE HELP ME WITH SOME ADVICES OR
HINTS...
2. Symmetric decryption with Blowfish. Even if the number 1 is succeded. How
to load the char * (or unsigned char *) of the key for the Blowfish
decryption?? PLEASE HELP ME WITH SOME HINTS...
Thousand thanks for everything. For at least reading this long email. And
sorry to bother you again and again. Wish you all the best.
Best regards,
