Overview
These functions decode and encode signing certificate attribute structures. For details about the semantics, examples, caveats, and bugs, see ASN1_item_d2i(3).
d2i_ESS_SIGNING_CERT() and i2d_ESS_SIGNING_CERT() decode and encode an ASN.1 SigningCertificate structure defined in RFC 2634 section 5.4.
d2i_ESS_CERT_ID() and i2d_ESS_CERT_ID() decode and encode an ASN.1 ESSCertID structure defined in RFC 2634 section 5.4.1.
d2i_ESS_ISSUER_SERIAL() and i2d_ESS_ISSUER_SERIAL() decode and encode an ASN.1 IssuerSerial structure defined in RFC 2634 section 5.4.1.
Return values
d2i_ESS_SIGNING_CERT(), d2i_ESS_CERT_ID(), and d2i_ESS_ISSUER_SERIAL() return an ESS_SIGNING_CERT, ESS_CERT_ID, or ESS_ISSUER_SERIAL object, respectively, or NULL if an error occurs.
i2d_ESS_SIGNING_CERT(), i2d_ESS_CERT_ID(), and i2d_ESS_ISSUER_SERIAL() return the number of bytes successfully encoded or a negative value if an error occurs.
