These functions decode and encode X.509 certificate policies. For details about the semantics, examples, caveats, and bugs, see ASN1_item_d2i(3).

() and () decode and encode an ASN.1 PolicyInformation structure defined in RFC 5280 section 4.2.1.4.

() and () decode and encode an ASN.1 CertificatePolicies structure defined in RFC 5280 section 4.2.1.4.

() and () decode and encode an ASN.1 PolicyQualifierInfo structure defined in RFC 5280 section 4.2.1.4.

() and () decode and encode an ASN.1 UserNotice structure defined in RFC 5280 section 4.2.1.4.

() and () decode and encode an ASN.1 NoticeReference structure defined in RFC 5280 section 4.2.1.4.

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.
