Hi everyone,
First I will admit being new to the list.
I am trying to solve a technical problem and I believe I have one last
piece to resolve. I know that from the command line I can duplicate
what I need to do using the commands:
openssl rsautil -encrypt -inkey pub.key etc
openssl rsautil -decrypt -inkey priv.key etc
For reasons which I cannot discuss I need to hide my private key
within my application and the decrypted data will also be used
internally and not written out to a file. My encrypted data will still
be in a file.
Using the rsautl.c source code as a model, I believe I should be able
to duplicate the command line in my source code using the functions:
RSA_private_encrypt(int flen, unsigned char *from, unsigned char *to,
RSA *rsa, int padding);
RSA_private_decrypt(int flen, unsigned char *from, unsigned char *to,
RSA *rsa, int padding);
For rsa_in, rsa_out and padding I plan to use:
unsigned char *rsa_in = OPENSSL_malloc(keysize * 2);
rsa_inlen = BIO_read(in, rsa_in, keysize * 2);
unsigned char *rsa_out = OPENSSL_malloc(keysize);
int padding = RSA_PKCS1_PADDING;
So my questions are, how do I replicate what load_key() to populate
pkey (EVP_PKEY *)? And, are they any data functions that can be used
to replace what the BIO functions do for files?
Thanks,
