.Pp
.Fn d2i_OCSP_SIGNATURE
and
.Fn i2d_OCSP_SIGNATURE
decode and encode an ASN.1
.Vt Signature
structure defined in RFC 6960 section 4.1.1.
.Pp
.Fn d2i_OCSP_REQINFO
and
.Fn i2d_OCSP_REQINFO

.Vt ServiceLocator
structure defined in RFC 6960 section 4.4.6.
.Sh RETURN VALUES
.Fn d2i_OCSP_REQUEST ,
.Fn d2i_OCSP_SIGNATURE ,
.Fn d2i_OCSP_REQINFO ,
.Fn d2i_OCSP_ONEREQ ,
.Fn d2i_OCSP_CERTID ,
and
