DESCRIPTION
These functions decode and encode X.501 Name objects using DER format. For details about the semantics, examples, caveats, and bugs, see ASN1_item_d2i(3).
d2i_X509_NAME()
and
i2d_X509_NAME()
decode and encode an ASN.1 Name structure defined in
RFC 5280 section 4.1.2.4.
X509_NAME_dup()
copies val_in by calling
i2d_X509_NAME()
and d2i_X509_NAME().
X509_NAME_hash()
calculates a SHA1(3) hash of the DER-encoded form of the name
*val_in. It is for example used by
X509_LOOKUP_hash_dir(3) to locate certificate files in the
file system.
d2i_X509_NAME_ENTRY()
and
i2d_X509_NAME_ENTRY()
decode and encode an ASN.1 RelativeDistinguishedName
structure defined in RFC 5280 section 4.1.2.4.
X509_NAME_ENTRY_dup()
copies val_in by calling
i2d_X509_NAME_ENTRY()
and d2i_X509_NAME_ENTRY().
RETURN VALUES
d2i_X509_NAME() and
X509_NAME_dup() return the new
X509_NAME object or NULL if an
error occurs.
X509_NAME_hash() returns the hash value or
0 if an error occurs.
d2i_X509_NAME_ENTRY() and
X509_NAME_ENTRY_dup() return the new
X509_NAME_ENTRY object or NULL
if an error occurs.
i2d_X509_NAME() and
i2d_X509_NAME_ENTRY() return the number of bytes
successfully encoded or a negative value if an error occurs.
