DESCRIPTION
These functions decode and encode ASN.1 structures used for OCSP responses. For details about the semantics, examples, caveats, and bugs, see ASN1_item_d2i(3).

d2i_OCSP_RESPONSE() and i2d_OCSP_RESPONSE() decode and encode an ASN.1 OCSPResponse structure defined in RFC 6960 section 4.2.1.

d2i_OCSP_RESPBYTES() and i2d_OCSP_RESPBYTES() decode and encode an ASN.1 ResponseBytes structure defined in RFC 6960 section 4.2.1.

d2i_OCSP_BASICRESP() and i2d_OCSP_BASICRESP() decode and encode an ASN.1 BasicOCSPResponse structure defined in RFC 6960 section 4.2.1.

d2i_OCSP_RESPDATA() and i2d_OCSP_RESPDATA() decode and encode an ASN.1 ResponseData structure defined in RFC 6960 section 4.2.1.

d2i_OCSP_RESPID() and i2d_OCSP_RESPID() decode and encode an ASN.1 ResponderID structure defined in RFC 6960 section 4.2.1.

d2i_OCSP_SINGLERESP() and i2d_OCSP_SINGLERESP() decode and encode an ASN.1 SingleResponse structure defined in RFC 6960 section 4.2.1.

d2i_OCSP_CERTSTATUS() and i2d_OCSP_CERTSTATUS() decode and encode an ASN.1 CertStatus structure defined in RFC 6960 section 4.2.1.

d2i_OCSP_REVOKEDINFO() and i2d_OCSP_REVOKEDINFO() decode and encode an ASN.1 RevokedInfo structure defined in RFC 6960 section 4.2.1.

d2i_OCSP_CRLID() and i2d_OCSP_CRLID() decode and encode an ASN.1 CrlID structure defined in RFC 6960 section 4.4.2.

RETURN VALUES
d2i_OCSP_RESPONSE(), d2i_OCSP_RESPBYTES(), d2i_OCSP_BASICRESP(), d2i_OCSP_RESPDATA(), d2i_OCSP_RESPID(), d2i_OCSP_SINGLERESP(), d2i_OCSP_CERTSTATUS(), d2i_OCSP_REVOKEDINFO(), and d2i_OCSP_CRLID() return an object of the respective type or NULL if an error occurs.

i2d_OCSP_RESPONSE(), i2d_OCSP_RESPBYTES(), i2d_OCSP_BASICRESP(), i2d_OCSP_RESPDATA(), i2d_OCSP_RESPID(), i2d_OCSP_SINGLERESP(), i2d_OCSP_CERTSTATUS(), i2d_OCSP_REVOKEDINFO(), and i2d_OCSP_CRLID() return the number of bytes successfully encoded or a negative value if an error occurs.
