# NAME

d2i_X509_SIG, i2d_X509_SIG - DigestInfo functions.

# SYNOPSIS

     #include <openssl/x509.h>

     X509_SIG *d2i_X509_SIG(X509_SIG **a, unsigned char **pp, long length);
     int i2d_X509_SIG(X509_SIG *a, unsigned char **pp);

# DESCRIPTION

These functions decode and encode an X509_SIG structure which is equivalent to the DigestInfo structure defined in PKCS#1 and PKCS#7.

Othewise these behave in a similar way to `d2i_X509()` and `i2d_X509()` described in the d2i_X509 manual page.
