Hey folks,
I've got a problem where I'm trying to decode base64 in memory and
BIO_read is returning 1 when I think it should be returning the
number of bytes read into buf after doing a base64 decode. The code
is based on the BIO_f_base64(3) manpage. The output should be "BOOGA
BOOG". The correct data is being placed in the buf but the length
being returned is incorrect.
#include <stdio.h>
#include <string.h>
#include <openssl/buffer.h>
#include <openssl/bio.h>
#include <openssl/evp.h>
int main(void)
{
char *data = "Qk9PR0EgQk9PRw==\n";
int dlen = strlen(data);
int inlen, totallen = 0;
char buf[512];
BIO *bio, *bio_out;
BIO *b64 = BIO_new(BIO_f_base64());
bio = BIO_new_mem_buf(data, dlen);
bio_out = BIO_new_fp(stdout, BIO_NOCLOSE);
bio = BIO_push(b64, bio);
while((inlen = BIO_read(bio, buf, 512) > 0))
{
totallen += inlen;
BIO_write(bio_out, buf, inlen);
BIO_flush(bio_out);
}
printf("\n%d was total len!\n", totallen);
BIO_free_all(bio);
return 0;
}
