DESCRIPTION
These functions decode and encode X.509 certificate policies. For details about the semantics, examples, caveats, and bugs, see ASN1_item_d2i(3).
d2i_POLICYINFO()
and
i2d_POLICYINFO()
decode and encode an ASN.1 PolicyInformation structure
defined in RFC 5280 section 4.2.1.4.
d2i_CERTIFICATEPOLICIES()
and
i2d_CERTIFICATEPOLICIES()
decode and encode an ASN.1 CertificatePolicies
structure defined in RFC 5280 section 4.2.1.4.
d2i_POLICYQUALINFO()
and
i2d_POLICYQUALINFO()
decode and encode an ASN.1 PolicyQualifierInfo
structure defined in RFC 5280 section 4.2.1.4.
d2i_USERNOTICE()
and
i2d_USERNOTICE()
decode and encode an ASN.1 UserNotice structure
defined in RFC 5280 section 4.2.1.4.
d2i_NOTICEREF()
and
i2d_NOTICEREF()
decode and encode an ASN.1 NoticeReference structure
defined in RFC 5280 section 4.2.1.4.
RETURN VALUES
d2i_POLICYINFO(),
d2i_CERTIFICATEPOLICIES(),
d2i_POLICYQUALINFO(),
d2i_USERNOTICE(), and
d2i_NOTICEREF() return a
POLICYINFO, CERTIFICATEPOLICIES,
POLICYQUALINFO, USERNOTICE, or
NOTICEREF object, respectively, or
NULL if an error occurs.
i2d_POLICYINFO(),
i2d_CERTIFICATEPOLICIES(),
i2d_POLICYQUALINFO(),
i2d_USERNOTICE(), and
i2d_NOTICEREF() return the number of bytes
successfully encoded or a negative value if an error occurs.
