NAMEd2i_X509_SIG, i2d_X509_SIG - DigestInfo functions.
X509_SIG *d2i_X509_SIG(X509_SIG **a, unsigned char **pp, long length);
int i2d_X509_SIG(X509_SIG *a, unsigned char **pp);
DESCRIPTIONThese 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(3) manual page.
