No one replied to my question, so perhaps I'm trying to do the wrong thing.
I'd like to store some text string in an initialization file. I'd like these to be
encrypted, so anyone browsing the file can't simply read them. I don't want
to encrypt the whole file, as there's plain text in it as well.
Then, I'd like to have an application decrypt the strings at run-time, so it can
use the plain text values.
So, I'd like to have a command line utility that I can give a plain text string
and password to; and a callable routine that I can call with an encrypted string
and a password.
Any suggestions for this?
Thanks.

I'm having a problem using the crypto api interface, and the openssl command line
Here's my dumbed down example. I can never get the command line to return the plain text -- when invoked with the same password the code uses. There must be something obvious that I'm doing wrong...
int main (int argc, char *argv[]) { unsigned char encBuf[8]; char * output = (char *)"out.enc";
const char * key = "testtest"; unsigned char data[8] = {'s','o','m','e','d','a','t','a'};
des_cblock k; des_key_schedule key_schedule; unsigned char iv[8];
string_to_key(key, (C_Block *) k); des_set_key(&k,key_schedule);
des_ecb_encrypt( &data, &encBuf, key_schedule, 1 );
int out_file=open(output,O_WRONLY | O_CREAT, 0666); write(out_file, encBuf, 8 ); close(out_file); }
Then, I try to get the plain text back with:
/*
openssl enc -d -nosalt -des-ecb -in out.enc
*/
Thanks for any help.
