libressl-i2d_PKCS7_bio_stream(3)

libressl-i2d_PKCS7_bio_stream3

Output pkcs7 structure in ber format

Usage

Crypto Library (libcrypto, -lcrypto)

#include <openssl/pkcs7.h>

int

i2d_PKCS7_bio_stream(BIO *out, PKCS7 *p7, BIO *data, int flags);

Overview

i2d_PKCS7_bio_stream() outputs a PKCS7 structure in BER format. It is otherwise identical to the function SMIME_write_PKCS7(3). This function is effectively a version of i2d_PKCS7_bio(3) supporting streaming.

Return values

i2d_PKCS7_bio_stream() returns 1 for success or 0 for failure.

History

i2d_PKCS7_bio_stream() first appeared in OpenSSL 1.0.0 and has been available since OpenBSD 4.9.

Bugs

The prefix "i2d" is arguably wrong because the function outputs BER format.
