D2I_POLICYINFO(3) FreeBSD Library Functions Manual D2I_POLICYINFO(3) NAME d2i_POLICYINFO, i2d_POLICYINFO, d2i_CERTIFICATEPOLICIES, i2d_CERTIFICATEPOLICIES, d2i_POLICYQUALINFO, i2d_POLICYQUALINFO, d2i_USERNOTICE, i2d_USERNOTICE, d2i_NOTICEREF, i2d_NOTICEREF - decode and encode X.509 certificate policies SYNOPSIS #include <openssl/x509v3.h> POLICYINFO * d2i_POLICYINFO(POLICYINFO **val_out, const unsigned char **der_in, long length); int i2d_POLICYINFO(POLICYINFO *val_in, unsigned char **der_out); CERTIFICATEPOLICIES * d2i_CERTIFICATEPOLICIES(CERTIFICATEPOLICIES **val_out, const unsigned char **der_in, long length); int i2d_CERTIFICATEPOLICIES(CERTIFICATEPOLICIES *val_in, unsigned char **der_out); POLICYQUALINFO * d2i_POLICYQUALINFO(POLICYQUALINFO **val_out, const unsigned char **der_in, long length); int i2d_POLICYQUALINFO(POLICYQUALINFO *val_in, unsigned char **der_out); USERNOTICE * d2i_USERNOTICE(USERNOTICE **val_out, const unsigned char **der_in, long length); int i2d_USERNOTICE(USERNOTICE *val_in, unsigned char **der_out); NOTICEREF * d2i_NOTICEREF(NOTICEREF **val_out, const unsigned char **der_in, long length); int i2d_NOTICEREF(NOTICEREF *val_in, unsigned char **der_out); 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.
