OpenSSL C example Base64 Decode,

[Nigel Sollars]

HI all,

I have a working example of Encoding base64 using the BIO methods but
decrypting a string is being somewhat problematic. The code in the man
page for decoding does not work either as the stdin new_fp does not hand
off / stop listening for input.

The openssl version is 0.9.8i

If anyone could supply a working example I would appreciate it,

Regards
Nigel

This works for me:
void base64Decode(unsigned char* pIn, int inLen, unsigned char* pOut,
int& outLen)
{
// create a memory buffer containing base64 encoded data
BIO* bmem =3D BIO_new_mem_buf((void*)pIn, inLen);

// push a Base64 filter so that reading from buffer decodes it
BIO *bioCmd =3D BIO_new(BIO_f_base64());
// we don't want newlines
BIO_set_flags(bioCmd, BIO_FLAGS_BASE64_NO_NL);
bmem =3D BIO_push(bioCmd, bmem);

int finalLen =3D BIO_read(bmem, (void*)pOut, outLen);
BIO_free_all(bmem);
outLen =3D finalLen;
}
