DESCRIPTION
These functions decode and encode PKCS#10 certification requests. For details about the semantics, examples, caveats, and bugs, see ASN1_item_d2i(3).
d2i_X509_REQ()
and
i2d_X509_REQ()
decode and encode an ASN.1 CertificationRequest
structure defined in RFC 2986 section 4.2.
d2i_X509_REQ_bio(),
d2i_X509_REQ_fp(),
i2d_X509_REQ_bio(),
and
i2d_X509_REQ_fp()
are similar except that they decode or encode using a
BIO or FILE pointer.
d2i_X509_REQ_INFO()
and
i2d_X509_REQ_INFO()
decode and encode an ASN.1 CertificationRequestInfo
structure defined in RFC 2986 section 4.1.
RETURN VALUES
d2i_X509_REQ(),
d2i_X509_REQ_bio(), and
d2i_X509_REQ_fp() return an
X509_REQ object or NULL if an
error occurs.
d2i_X509_REQ_INFO() returns an
X509_REQ_INFO object or NULL
if an error occurs.
i2d_X509_REQ() and
i2d_X509_REQ_INFO() return the number of bytes
successfully encoded or a negative value if an error occurs.
i2d_X509_REQ_bio() and
i2d_X509_REQ_fp() return 1 for success or 0 if an
error occurs.
